r/audiophile - Sound Diffusion On The Front Wall?! Great! www.AcousticFields.com

[@mrburn8665]

The white room that starts at 2:05, have the Svanå Varitunes V6 Variable Helmholtz resonator that take care of the low frequency 25-65Hz in the corners!

[@AcousticFields]

The corners are not your problem. It is the whole wall. The corners are ust a symptom of larger wall issues. A single resonator may absorb 5%. Its not enough horsepower.

[@EggMCMUFFIN-e4l]

@@AcousticFieldsexactly. Treating one section and neglecting the others is just a slice of the pie. Treat them all and they all have equal performance and resolution.

[@EggMCMUFFIN-e4l]

Your knowledge sir, is fine wine. I’ve followed your tips to a T and the sound from my room is incredible. So good I ended up removing MORE speakers from my room because of how much more projection just my front speakers alone produce. I got rid of my sub and my center channel, with zero loss of resolution, if anything, I gained even more. Plus some speaker mods etc etc. but I’m stunned how little folks pay attention to proper treatment, spending thousands on equipment and still complaining about fidelity…

[@AcousticFields]

One could make a valid argument that the room is responsible for over 60% of what you hear. That said, few pay any attention to treating the room. It has never made any sense to me. People spend thousands on new gear for a small increase in resolution when that money spent on the room will produce much greater results. I receive many calls from people that are fence sitting on whether to buy a new piece of gear or treat the room. Those that decide to treat the room all most always end up keeping their existing gear. Most comment on hearing all the reasons they originally bought their gear have come back to them with increased room resolution.

Generally we have big screen TV's with hifi system. How we place 1d diffisors with TV ?

[@AcousticFields]

You can position on both screen sides. A ceiling diffusion system would compliment this restricted surface area front wall coverage.

I think you have to fix the audio in your new series. Please. I like your skills in the subjects your talking about. Thanks from Sweden.

[@AcousticFields]

Working on it!

[@peanutbutterjellyjam2179]

With the second setup, the greatest improvement was the cable lifters.😉

[@AcousticFields]

I seriously doubt that.

[@yettamon956]

audioquest froglifter is suck, reduce the dynamic and blacker the sound

[@peanutbutterjellyjam2179]

@@AcousticFields I' really wonder why it is that 'audiophiles' use cable lifters. I understand, for style, but how can any reasonable person expect a difference in sound?

[@breckisaac5378]

I have an 8ft opening into my 14’ X 22’ listening room. Question- do I put the speakers in front of the opening with my listening chair facing the opening? Or the other way around…with listening chair facing the wall? Hope that makes sense.

[@AcousticFields]

Always place open areas behind the listening position. This set up reduces rear wall pressure and reflection issues.

[@breckisaac5378]

@@AcousticFields thanks!

[@Paffi.]

why is diffusion at the front wall good? wouldn´t be (thick) absorbtion better, as the lower the frequencie the more omnidirectional it is, hence firing (from the speaker) backwards to the front wall are only low frequencies? this diffusors won´t affect that at all and may only diffuse some late reflections of mid/highfrequencies, which may alread be absorbed / diffused at the other walls.

[@AcousticFields]

Diffusion is a psychoacoustic tool that can enhance specular reflections from surface areas or "hide" them depending on distances involved. Front and rear wall diffusion for two channel creates a wider, deeper, and higher sound stage with improved middle range definition..

[@Paffi.]

I know what diffusion does, but I'm specific asking why the front wall, where it is not really effective​@@AcousticFields

[@EggMCMUFFIN-e4l]

@@Paffi.if you properly listen, you can literally hear the sound travel across the wall when you listen to the music, IF you have a proper enough setup. The wall is a hard, flat surface, and the sound you get from it is unpredictable. With properly tuned diffuser panels, you can excite certain frequencies causing a psychoacoustic effect of enhanced projection of the tuned frequency. It takes a properly tuned and experienced ear to hear this.

[@oohtob6685]

You say not far away enough from the side wall's. Check. But in that situation. What happens if the speakers are to close together? For so many that have narrow room's and the inability too put along the long wall what's the option? Not everyone has the means or size to treat a small room. ie 12 by 14ft. So basically im asking, nearer too side wall's or close together?

[@AcousticFields]

Neither is accepatble. In this situation, it would be best to find another room size that will permit a proper set up.

[@oohtob6685]

@@AcousticFields unfortunately in the UK this is the norm with the average room size unless you are rich enough to build a room from scratch. Next doors property cost them 1.6 million. 12x14ft foot front room. Property prices here are spiked buy amount of rooms not size.

[@dashcammer4322]

How much low-freq treatment would the 2:03 room need? It looks like it's fairly large with a much higher than average ceiling.

[@AcousticFields]

As a general rule, you need to look at a 50% surface area coverage on each wall, if you are going to reduce pressure levels below audibility.

[@sloboat55]

Excellent. Does help.

[@AcousticFields]

Glad to hear it!

[@stephenlegg262]

Unless you have a huge listening room I suppose it’s best to use headphones.

[@AcousticFields]

Maybe. They are both different approaches. Headphones contain minimal reflections and vittually no pressure. Rooms have pressure and reflections. One is direct energy with minimal reflections from the hreadphones themselves and one is a combination of both pressure and reflections. We try and get the resolution of headphones within our rooms.

[@stephenlegg262]

I see. Thanks for clarifying.

[@mudchair16]

The audio on these videos is very poor. A fairly inexpensive mic will do the trick.

[@n.lyndley.9889]

The irony!

[@AcousticFields]

Not irony. A technical issue that needs resolution.

[@glenncurry3041]

You promote using the long wall in smaller rooms you have reviewed. Most home speakers today say to keep them away from the front wall by at least 3'. A foot or two of speaker cabinet depth and the front of the cabinet is 5' - 6' into the room? If you have to leave 4' behind the sofa, that leaves 2' from the front of the speakers in a 12' deep room.

[@AcousticFields]

Find another room with more appropriate distances. You can not cheat with set up. Set up is the foundation upon which you build resolution.

[@glenncurry3041]

@@AcousticFields Yes when other rooms are options. Some are stuck with what they are stuck with.

[@eur1gys]

Denisse's videos are very insightful indeed and his logic to use the long wall is completely understandable. But Glenn's thought is exactly as mine. Given the fact that most of us can't find another room in the house - seems to me that putting speakers on the short wall+dealing with side wall reflections is way way easier than putting them on the long wall and dealing with 2" speakers distance+2" real wall distance. It's a matter of what's better situation in many of our long but narrow (10-12") rooms. Dennis can add his further thoughts on this - perhaps even to do a separate video to discuss pros/cons of both setups in such a room (say 12" x 18")
