Move the couch forward. Move the speakers out from the the front wall. Get the floor-standing monitor speakers up from the floor. Decouple them from the floor with transport dollies or the feet delivered with the speakers. Use damping mats under speakers so you can to reduce bass and vibration. Use absorbers and diffusers behind speakers. Use diffuses behind you on the wall. Good thick carpets on the floor. Heavy curtains that you can slide away to the corners of the room when you are not listening to music. They are great for covering large TV -sets and windows. More?. Keep your doors to the listening-room open to let out the excess bass pressure-waves from your speakers. Do not place subs in the corners. Keep the mid-tone drivers at he same height as your ears. Listen then if there is some "splash" from the ceiling and treat it with diffusers and/or absorbers. Decouple amp, cd-player and record player from the table-top/floor with absorbing mats feet. Then start with the fun part with power-cables, speaker and IC... It's like gardening. You are not supposed to get a perfect finished garden. You are always on the move and improving or just changing...

[@krischanrudolph6005]

thaks for your amount of tip you gave here

[@Oystein87]

Alot of good tips here. Some of them I have had a little plan of doing myself. But remember to not overdampen as that also will ruin the sound and make it less lifelike. Damping under the speakers wont help if you live in a basement or ground level. But in hanging floors (room underneeth) it might in some cases. Decoupling speakers and equipment only helps in some cases when you have loads of vibration. Mostly it's estetics akd placebo. But cables.. That helps on sound. Uhm.. Opening my door gives me even more bass dude...😅 So that is not always the case. In all small rooms I have had it sounds best when the door is closed. And use absorbers and diffusers only where needed. And that could be anywhere and not neccecarely the places you mentioned.

[@blobeyeordie]

Acoustic room treatment is arguably one of if not the most crucial part of the listening experience(especially in smaller rooms) next to speakers and is unbelievably overlooked. I cant believe how many blow thousands upon thousands on gear and dont even consider treating the room. Youre just hitting the point of diminishing returns going that path when you can spend a fraction or less with the DIY route on proper treatment, and achieve an infinitely better listening experience even with mid-low end gear.

[@oldestpunkinargentina7766]

200 bucks on DIY room treatment went a longer way than 5K on equipment for me.

[@limitlesssky3050]

Or you could do both

[@Oneness100]

Totally agreed. the one thing I can say Is the most difficult thing to do is to find someone that will actually help you in figuring out what treatment you need, and the other side is to get the room to sound it's best, you either have to start from scratch or spend at least $15K to $20K on room treatment. It's always dealing with the weakest link syndrome. When you get involved with room treatment, whatever treatment you use, you'll either begin to hear the deficiencies in your room that's generated from the untreated areas or whether you choose the right product/materials to treat the room.. As long as you know that going in, you'll learn to have fun with it, and to at least understand where to spend the money.

[@Oneness100]

@@oldestpunkinargentina7766 $200 is only going to buy you some building insulation to use as side wall reflections. Yeah, it makes a difference if you have enough wall coverage, but it's still far from fixing the problems in the room. And you have to be careful using building insulation as treatment in room acoustics. it wasn't designed for that application and their absorption coefficient curves isn't optimized for music and speech. It's more for thermal insulation from hot and cold in a living environment.

[@DuSeun]

It's not overlooked, it's just that most people don't want a living room full of bass traps and carpeted walls

[@bobbyearl60]

I went nearfield a few years back and solved a host of issues that are mentioned here. An added benefit less amplifier power is needed,not to mention I was now able to afford better quality speakers, albeit smaller. Yet I still use all my original upstream equipment from my former whole-room system. Its not for everyone, but if one tends to listen alone, and rarely if ever uses the system for social events, etc,I recommend giving nearfield a try.

[@FOH3663]

Superb results and quite easy to DIY; As much bass trapping as one can aesthetically pull off in the entire room... ie, entire corners, entire wall surfaces. Face the trapping with 6mil plastic (Visqueen) ... this prevents excessive damping via reflecting 600hz and up. Anywhere appropriate, place diffusion/scattering in front of those Visqueen faced traps. This is all about LF decay times ... which is likely the biggest problem, easiest low hanging fruit issue to address. Fast, high resolution bass clarity will result. That's part A, to issue #1, in essentially every room, ie., poorly resolved bass due to uneven decay times. ----------------- Part B, to issue #1 is bass/modal resonances. Placement experimentation, and EQ, in that order. • A room's resonances are fixed and solely determined by the room's dimensions. • Loudspeaker placement determines which modes are excited. • Listener location determines which modes are heard. Those three elements are crucial, yet oftentimes misunderstood. Then on to EQ, (be it dsp based automated Dirac or equivalent, or simply parametric EQ with measurements). If problematic frequency peaks remain in the response below ~250hz, EQ is a must. I say approx 250hz because it should only be applied below the transition frequency. Attempting to EQ above the minimum phase region corrects in one physical place ... thus creating FR issues elsewhere. This 250hz approximation is the transition region... whereby the sound propagation changes from "waves" to "rays" EQ is a valid tool within the pressure wave region below, not in the ray acoustics region above. An EQ change in the wave acoustics frequencies, results in a change evenly everywhere in the room. However, an EQ change in the ray acoustics region above, results in unpredictable changes throughout the space due to superposition peaks/dips. That's issue #1, ... bass clarity.

[@StewartMarkley]

Nice addition to this thread.

[@travisylvania6730]

I have bought GIK panels and I have found that they have made a tremendous difference in my room. I would recommend that if your are skeptical, to just dip your toe in and buy 2-4 large panels and you will hear a clear improvement. That way, you will feel more comfortable with spending the necessary amount to treat your room (whatever that may be). Room treatment are NOT snake oil. I think dollar for dollar they are the most cost effective way to improve sound that you already are getting. But don’t think you need to spend 1000’s to see a big improvement either. Happy Hi-Fi!

[@Diatonic5th]

Agreed! I bought two large GIK Alpha Pro Diffusor/Absorbers panels for the wall behind my speakers and they made a big difference. After adding a shag carpet and heavy curtains I'm finished with my room now. I'm actually afraid I would over-dampen my room if I added anything else.

[@denniswade4998]

I went to nearfield listening in my room, and it did help with removing a lot of room problems.

[@Oneness100]

For near field, you need to have about a 3 ft triangle between speakers and you. Also, the speakers need to have at least 4ft distance from any wall. So, you realistically need at least a 12 or even 13 ft width in your room, otherwise you'll still get reflections from side walls. Also, if you use a sub, place it next to you, the listener, and put on a platform to raise it higher, at least 6 to 12 inches higher.

[@erikquinn707]

This was great Steve!! Thanks, very helpful info regarding acoustic room treatments.

[@TorToroPorco]

I helped a friend set up his new speakers after moving into a new apartment. Luckily it was a fairly large space with an open concept living room and dining room so he was able to pull his speakers into the room and wall reflections were not an issue. The nearest side boundary was his floor to ceiling windows that had drapes to minimize reflections. As with many people he had his TV between the speakers so I brought over some large thick beach towels and threw them over the TV and it made a noticeable improvement to the stereo imaging and clarity much to the surprise of my friend who was very sceptical and reticent to covering up his TV because he thought it looked silly.

[@johnjeffery6638]

Doing a near field deal with Klipsch 51PM and an additional 8” Sub ..its entertaining ....and I’m going to go with cans for serious music listening . Great video as per usual Steve ☕️ thanks.

[@LookSee]

Placing the sub next to or near the listening chair worked well for my set up. I can easily reach over to the volume control and adjust the bass. UB5s with RSL 10 speedwoofer. 11x14x8 room carpeted.

No listening fatigue on this channel for sure! You continue to do what you do best Steve... give us your honest opinion on all things Audio..... The Audiophiliac Show: (like Clapton once sang ) Let it Grow!! 👏👏👏 Damn those shirts Steve! 🍻👍

[@06mukhtar]

I had been playing with this for a while and finally found out that near-field listening was actually ideal for me. It so turned out, ironically, that position the speakers there also reduced most of the reverbs that would otherwise affect listening experience (luckily), and getting closer to the sub helps with avoiding the annoying standing waves. My room is 12x25 ft with 10 ft ceiling. The speakers are facing the 12ft direction.

[@jlutell]

Several years ago I converted an expandable attic to my audio visual room. I maintained the basic shape of the space making the cross section trapezoidal for many of the reasons you discussed. Carpeting, books on shelves, and a couch are my treatments. No slap echo or standing waves..I'm going to miss it when I have to downsize.

[@jimshaw899]

Enjoyed this. Remember an oft quoted comment in music that "The most important instrument in an orchestra is the [room]."

[@johnjeffery6638]

AWESOME!! TOTALLY AGREE.

[@keithmoriyama5421]

Building a purpose built 'studio' type listening room, it occurred to me not to finish the ceiling. Since the supporting joists were running parallel to the speakers I decided to modify them into one giant diffuser/absorber. The very top of the ceiling (bottom of the main floor) was lined with absorbtive insulation and a series of diffusers both internally within the joists and interspaced where the ceiling would normally be resulted in an infinite ceiling with a touch of controlled bounce back. Black cloth covers the rest of the 'false' ceiling. Result: A full 9' basement ceiling, savings in money and a great improvement in sound.

[@brendanlawton7518]

Great ideas. With a little DIY the panels don't have to cost much either, I built mine for the cost of the insulation I used. Lots of info can be found easily. I made a rectangle stuffed in my insulation a little extra to get it off the walls as far as possible added my own fabrics. Can even look any way you like this way. Did wonders for my sound stage😁👍

[@matbasterson520]

My music room is the dreaded "almost cube!" I gravitated toward the near-field listening arrangement. Not ideal, but it works. The wall behind the speakers is a 1/4" fake brick panel, it's really heavy and it makes a difference.

[@petekutheis3822]

GIK is what I have and like.

[@ManosPairis]

Thanks for the advise Steve, will put it to good use XD

[@calebkeen8967]

I'm living in 11X11X8 foot cube-room hell. I've solved as well as I can with open-baffle speakers that minimize first-reflection point issues, sitting relatively close, light absorption on the back wall and placing my subwoofer very close to my listening position while taking extra care to properly time-align it to the mains. It's hard to get a wide, deep soundstage in a room this small but imaging, tonality and microdynamics sound very good as long as I don't push things much past 85 db. Even bass tonality and impact is good as long as I don't push things really loud. To achieve large scale sound with good macrodynamics in a room this small requires significantly more treatment than I'm willing to buy or build.

[@Diatonic5th]

If you don't mind my asking, what open baffle speakers do you have, and how far are they from your front wall? I've been looking at purchasing the Spatial Audio M5 Sapphires for my 11'X15' listening room.

[@calebkeen8967]

@@Diatonic5th emerald physics 3.4, now out of production. I have them pulled 5 ft from the front left and right corners on a diagonal, with the direct sound crossing 3 ft in front of my head when in listening position. If you draw a straight line from the back of each speaker you will be in the corner. This was the easiest way to create most space between the back of speaker and front wall, which I've been led to believe is best for these kinds of speakers. Would love me some Sapphires, good luck!

[@calebkeen8967]

@Roland de Rooy not all the frequencies below 55 hz are offensive at 85 db or less but there are definitely some nulls that are unfortunate and can't be managed without treatment.

[@calebkeen8967]

@Roland de Rooy Yes, it's picking poison. I do enjoy headphones now and then but ultimately prefer speakers. I could chop all the low to get a more linear response but I find I ultimately prefer to have an acceptably good experience of most of the low by carful placement of mains and sub, time-aligning subs and mains, listening at relatively low db (70-80), managing peaks with DSP and living with the nulls. I look forward to one day having a better room which wouldn't require that I cover 30% of the surface area (minimum) with bass traps like this one!

[@timothylewis2450]

I feel ya @Caleb Keen. Mine is 12x12x8, with a window on one side and bathroom opposite. At least it’s carpeted. Thinking of trying some bass traps to start but not optimistic. Any suggestions from anyone appreciated! 😊

[@BongEyedBastard]

My room isn't as loud as Steve's shirt.

[@miguelbarrio]

I have horn speakers. They are more directional than most other designs and because of this I find they project more sound directly to you than the reflections.

[@Drackleyrva]

That was my question----are horn speakers better suited for certain rooms vs standard speakers?

[@2ChukBuk]

I have horn speakers as well with hardwood floors. A nice large rug with carpet pad really helps with the low end. One needn't get too crazy with room treatments as Steve says. And don't forget to play around a bit with speaker position as well.

[@miguelbarrio]

@@Drackleyrva Horn speakers are more directional in the midrange and higher frequencies. This means that the reflections you might have will be comparatively lower intensity than the direct sound. This is not necessarily an advantage, call it a “feature” of the horn design. It has the drawback that toe-in can greatly alter the character of the sound, so you need to figure out toe-in more precisely than with a speaker with wider, more even dispersion. I do want to point out that while mid and high frequencies are more easily treatable with absorbers or diffusers, the bass is not easy at all because it is about the room modes rather than the speakers themselves, and changing the fundamental modes (those where the sound wavelength is twice the distance between walls) is almost impossible to do with traps of any sort (you’d have to build a pretty deep soft surface on one of the walls). This is ameliorated when rooms don’t have parallel walls: the modes in this case get washed out. Room correction (ie digital room correction) can be very effective in reducing bass peaks (ie room modes) whereas it is ineffective at increasing bass in bass lows - because the latter are cancellation modes and if you put more energy in, you just cancel more of it. So digital room correction is not necessarily the key to solving these problems.

[@Drackleyrva]

[@carlosbauza1139]

Nearfield listening is great. A 3-foot equilateral triangle ( two speakers and one listener) at the center of the room is T-H-E ideal starting point.

[@leekumiega9268]

While mentioning the Ohm Walsh 2000's you did not mention that rear and early side reflections do not need correcting as they help widen the sound stage even more while giving phenomenal imaging and a sit anywhere sweet spot.

[@sopark434]

Just subbed, I watch all of your vids.

[@TheMirolab]

In my studio, I've got large absorption panels behind and to the sides of the speakers. They really help! Then I hung TWO 3'x8' panels on the ceiling, and that was a step too far! They sucked all the life and energy out of the room, and it felt unnatural. I tried for a week to get used to it, and once I took the 3x8 panels back down, the life came back. I now have 2 small 2x3 panels at the critical reflection points, and it's just about right. I plan to make diffusor panels for overhead to disperse the reflections without sucking out too much energy from the room.

[@harryconover289]

The room is by far the biggest component of the sound and is by far the most effect for money spent

[@jeffn1384]

I used a cheap rug on the floor and it worked well but then I read about audiophile grade rugs with oxygen free fibres so I'm now saving for one of those.

[@limitlesssky3050]

Wth is an oxygen free fibers? When it got exposed to actual air, with oxygen, then it won't be oxygen free fiber, no? Not trying to be judgemental or anything, won't a thick rug works the same though?

[@tomkohman4620]

I installed the free REW software on a laptop and purchased a calibrated microphone to take actual measurements of the room response. It's a real eye opener. With experimentation I was able to cure some bass nulls, higher frequency response was highly variable depending on seating position. Just a few inches make a difference. Getting flat response across the audio spectrum would be very difficult.

I can pull the speakers off the wall and place my chair in the ideal sweet spot. Until I got this space set up, I didn't really understand the importance of the space. I'm my younger, more naive days I just thought a great pair of speakers was all that mattered.

[@damianzaninovich4900]

I liked your previous advice of setting up on the long wall rather than the short wall, just to experiment. So in a 17 by 12 room with an 8 ft ceiling I have Canton Vento Reference 7 speakers 3 ft from the back wall and 4.5 ft from the side walls in a 1951 room with 3 doors, one leading outside which makes it sound better but with the sounds of nature. The back wall is a little more than half brick from a fireplace and the rest is dual layered old maple wood paneling with one side wall all windows with shutters. No room treatments just a lot of furniture. My short backed listening chair is in a 7 ft equal lateral triangle. Easy to adjust bass balance by moving chair a little forward or back. All music I listen to sounds really good even at the lowest volumes. I can lay on the couch 3ft adjacent from one speaker and it still sounds good like I’m doing now listening to the Sundays Blind over and over.

[@MichaelSmith-oz3sv]

I have the same speakers. Nice to see here in the US.

[@damianzaninovich4900]

I bought them because they were 65lbs not 105lbs, have rounded fiber board cabinets with the tweeter below the mid driver which I like. They’re made in Germany and they’re a 10 yr old design being closed out new for $3,000 which is what I think they cost in Germany. Easy to live with, to me they sound like a full range driver even when I walk up to them to change music.

[@MichaelSmith-oz3sv]

@@damianzaninovich4900 I've had them for 10 years. I always appreciated the rigidity of them. My cousin knocked one of the speakers over a month ago. After I buried his body, I checked it and noticed the mid-range had been compromised around the outer surface in the cone, thought no cracks. LUCKILY, I haven't noticed any damage to the sound quality after many hours of use. So if you were ever thinking of knocking one over for whatever reason, it should still work fine.

[@maestro0428]

Hey Steve. Thanks for the video! I've been insulating the celling and air ducts in my listening room (the ceiling is unfinished). My room is also not square or rectangle.

The room itself isn't the only part of the equation. You also have to fill it with things that don't mess up the sound. Furniture, objects (books, records, etc), and people will affect the volume of sound, reflections, distortion, absorption, etc.

[@sbrazenor2]

@Lloyd Stout And there are different types and configurations of that, too. Different thickness, different processes (laminated, tempering, insulating, etc) that change features of the glass, different shapes and fixtures (flat vs small pane, vs some ornate stained configuration). Window coverings are also an issue. I use canvas roman blinds with insulating baffles, for example, which seem to be good at diffusing the sound instead of just reflecting it. I also have different walls than a lot of people. I have stone block construction in the outer walls, then insulation, and then lath and plaster on the inside. It seems to absorb a lot of the energy. Outside, with my system up relatively loud, it's almost inaudible with the windows closed. (I love my music, but I try to be a good neighbor.)

Hey Steve, I have a 11 ish ft SQUARE stereo listening bedroom. More precisely W3,42 x L3,47 x H2,77 meters. What you said is what I'm experiencing. I have to make do with near-field or face the room boom. I have a pair of Neat Motive 2 (12cm woofer and 76cm tall) loudspeakers driven by a Naim NAP250DR and one SVS SB12-NSD subwoofer. As you can imagine, the sub almost have to go in the middle to avoid the boundaries. My amp is too much for my speakers, at some point the speakers will produce that prrrr sound reaching the excursion limits with the kick drum. At this point, I wish I had a tad stronger speaker. At the same time I know this speaker cannot have rear firing port and probably should not be a multi driver loudspeaker. I'm thinking about another pair of down ported 2 way tower but with 17cm woofer to resist more. A little taller would also help with the near-field listening because I have a computer desk with a 27 inch LCD blocking the speakers a little. I have a large carpet covering all listening area, curtains behind my listening position covering a large sliding window and a wardrobe on one of the walls on the side more distant of the speakers. What would be your first room treatment experimentation? Absorbers on the side walls at first reflexion points? One wall has the wardrobe covering the probable location of the absorver. Osvaldo

[@cnhhnc]

I have some vintage speakers in my finished basement room 20 x 10. Any attempt to put speakers on the long wall (20') results in lackluster sound. The SAME speakers on the short wall with the 20' as the space they play into sounds totallly different. They come into their own. Sound like DIFFERENT speakers. Speakers have a 37hz-20Khz +/- 3 db range. My conclusions, the bass is too smeared does not have the space to propagate when it's less the 10' but can breathe when it's closer to 20'. This was a real eye-opener when it came to understanding room effects/problems. The room has the usual acoustic tile drop ceiling, cement floor which is carpeted, a foundation wall that is paneled with wood, and three other paneled walls. Surprisingly, almost ANY speaker, and I mean ANY sounds best against the SHORT WALL!

Steve forgot to mention planar speakers, like Magnepan, Soundlabs, etc, they do not send sound to the floor and ceiling and not much to the right and left, the sound coming off the back is the issue... speakers have to be far away from the back wall, or diffused/absorbed...

[@kohnfutner9637]

How do you know where your first reflections are happening? I always see people with diffusers behind the speakers, on the back wall and on the sidewall almost straight across from the speaker. I read on some scientific website that said back wall needs 4" thick some substance I forgot.

It's worth remembering that a room like an anechoic chamber won't sound good. Recordings are made to allow for some room reverb.

If one were to build a new house and if the living room was the listening room, what material should we use to build the living room? To get the best Accoustics. The walls and flooring materials in particular. Thanks.

[@FOH3663]

Great question, but one not easily answered without greater detail... ie.; application 2ch stereo? multi channel home theater? any sound isolation needed from adjacent spaces? More important than materials, is the room's symmetry. Absolute Left to Right symmetry is essential if designing/building from the ground up. Then incorporating LF trapping integral into the boundary surfaces, and then facing that trapping with MF/HF diffusion as needed and where appropriate. Typical building materials like sheetrock and wood studs are fine, however implementation of triple leaf sound deadening can help both room acoustics and keeping the sound in the home.

[@tomwebb7091]

It cant be underestimated.... the room is the single most important thing to consider when trying to get good sound. I have the unfortunate predicament of using an attic room as my man cave / hifi room. Floor size is 4 x 5m so pretty fair size but the upper is concave and narrows to the roof. These uppers are hollow when knuckle rapping and the whole thing is acoistically alive. The floor is wood suspended with thick carpet and again not inert. All this means no matter what equipment i use i am hearing the room and it ruins everything. Net result is im selling off all my 000's of pounds of hifi as i simply dont enjoy sitting and listening to my room.... and the noisier mains i also suffer up top!!! The reality for me is my £300 grado headphones plugged into the Marantz sacd player sound far better in many ways than £32k worth of all valve pre/power amps with Tannoy Kensington GR on the end and its made my hobby a box swapping nightmare in a room that just wont let my kit sing.

[@louiesipes2257]

Lucky in that I have a pass through into the kitchen that the wife hates. So there have been drapes over it for years, also drapes over the two windows on the other side. Coat rack behind the left speaker and an open hall behind the right. Big stuffed sofa at the back of the room. Not ideal but it works.

[@brucemibus9523]

Hi Steve, I am lucky enough to have a dedicated designed room that pretty much matches one used by reviewers for a movie magazine in the USA. The half wave is 19Hz long, a bit over 10 Metres with width at 7.2 Metres, ceiling max is 3.3 Metres down to 2.7 at the rear. Rear wall is offset by about a foot side to side. Anthem dsp does room eq in the bass but nowhere else. Wall and ceiling are resilient mounting (double layer plasterboard) except for front wall that is solid mounted. Wish you could hear just how calm the sound is. Even moderate speakers are ok in here.

[@scotthintz8875]

I'm Building a new home that will have a dedicated room that is the same size as yours. 20 ft wide, 30 ft long, 10 ft ceiling in the front, 9 ft ceiling in the rear. What do you mean about the rear wall being off set? I don't follow. Thanks

[@brucemibus9523]

@@scotthintz8875 Hi Scott, the rear wall is not parallel with the front, with the right rear being 300mm closer to the front than the left rear. Trust me here, it's a critical thing to do as it kills bass resonance almost completely. By doing this I can run with little eq at all, and only subs are running it. The tier raised floors are made slightly flexible by not hard joined to the walls, and rock with heavy bass, adding to the feeling of explosion and drama.

It is the main issue to reproduce great sound.i've been dealing with this for many years.for smaller rooms,I recommend small stand mounted monitors.most great British speakers are of that type.most listening rooms are in older dwellings that tend to have smaller rooms.Was an audio consultant for some years and I can't tell you how many of the Ultra High End systems I've heard that sounded horrific!.room treatments are very helpful,but careful system matching is very critical! In my opinion, the 180°dome tweeter set high end audio back 30years.the main culprit for most undesirable reflection.i found that speakers with ribbon or horn tweeters have better directivity and do not see the baffle like domes.

[@Wuppie62]

Does anyone have thoughts about or experience with using an armchair with large 'ears', or 'eggchair'? Well placed, I guess this way you could receive more of the direct sound from your speakers and less indirect/reflected sound...without having to do a massive room haul over. Right?

[@C--A]

I've also got thick velvet curtains, also blinds on the windows. The thing to look out for when buying curtains is the spec of weight of the material per foot. The higher the better. The sound performance compared to when I had thin curtains and no blinds is night and day. Most rooms have curtains so why use thin curtains that the sound will pour through to the reflective glass windows.

I have been lucky, I had a great sounding room once I moved the speakers to the long wall using bookcases to defuse sound and listening nearfield. But it was time to tear that room out for a new master suite. So up to the attic I went. Rectangular room with a knee wall behind the speakers. Building a shed dormer, I gently sloped the ceiling down to minimize reflections with the help of an acoustician and a fine carpenter.speakers three feet out into the room, minimal side and rear reflections and I am a happy camper. Vandersteen 3A Signatures, nearfield listening, 2x10 floor joists and no bass boom at all. Ray Brown, Christian McBride and John Clayton sounds superb in my room.

A big problem is that many homes and apartments have an open floor plan where the kitchen and livingroom are part of the same space. This is bad acoustically for many reasons, and worst of all you can hear the refrigerator 24-7. Refrigerators are the enemy of good sound.

I have an open floor plan as you describe, tile floors, cathedral ceilings and all. Outside of potential appliance noise (not much of an issue for me), my A/V calibrator did his tests on the room and advised where to put some sound panels. On his next visit with sound panels in place (already had a thick rug in the listening area and heavy curtains on a sliding glass door), he remeasure the rooms acoustics and listens to several test disks and said that it’s now a really good listening room that measures and sounds excellent. Now, I just have to keep wifey from clucking and I’ll be golden.😁

You need a carpet to tame the reverberation. If you have wooden flooring then get a very thick rug. Plus some acoustic absorption panels (ideally at least 4inch depth) on the side and rear walls.

[@janwillemkuilenburg7561]

Hi Steve, very good tips. I have an unusual tip on speaker placement. I suspended my floor standing speakers halfway between floor and ceiling. In front is a rug on the floor. The horizontal towing is past my listening position. Vertically the speakers are leaning downwards a bit with the front, also directed behind listening position. The sound stage is a bit higher than usual, but it is huge this way and reflections are minimal. Behind the speakers I tune the level of absorption by curtains. I am lucky that the space is deep (12 m), but otherwise I would have absorption on the rear wall.

[@RasheedKhan-he6xx]

There's some sense to raising floor standers. On mine which have the woofer above and tweeter below the tweeter ends up lower than my ears when seated. Lifting the speakers about 8-9 inches would solve this but I just never get around to it.

[@janwillemkuilenburg7561]

@@RasheedKhan-he6xx That is very strange, because the tweeters indeed should be at or above ear level. You could raise or flip them upside down in order to improve the high spectrum.

[@RasheedKhan-he6xx]

@@janwillemkuilenburg7561 Its not strange at all. Its quite a common design. Another common design is a D'Appolito array, where the tweeter has one midwoofer above and another below. All of these have to do with phase shift and time alignment of the sound from the two drivers. That is also why some companies still make full-range single drivers or concentric tweeters and woofers, like Kef.

[@tomwebb7091]

Having infinite baffle (some ATC) is always best or transmission line (eg PMC)/thin slot (eg some Wharfedale/Tannoy prestige) for alot of rooms, especially smaller rooms.

[@user-od9iz9cv1w]

Great advice as always. Love the suggestion to try a towel in front of speakers. I threw a bunch of towels in the open fireplace behind the speakers and was amazed at the improvement. I have a carpet over concrete floor, but it may not be enough in front of the speakers. If the towel improves then I can throw an area rug over the carpet.

[@RasheedKhan-he6xx]

Same, carpet on marble. I dropped a couple of large floor cushions in strategic locations. Made an actual difference. Another thing is, get a low back chair. Some people do know not to sit right back against the wall but then get a leather high backed club chair. You will get reflections happening right behind your head. Try bringing a pillow from your bed one day and put it behind your head you'll see.. er.. you'll hear what I mean.

It's just as having bare drywall man; same reflectivity.

Sitting on a big cloth couch and throwing a plush area rug in front of your speakers help a lot. Also windows should have heavy drapes in front of them.

@@AllboroLCD Good ! My DIY panels are wooden-framed, fabric-wrapped and look quite nice. Make the rug as big as you can; cover the distance between speakers and couch if possible, and make it wider than distance between speakers. In this way you not only minimize floor reflection, but attenuate those that reach the ceiling and bounce back smearing the direct waves.
