Subwoofer Set Up & Optimization

[@applesauce2710]

Thank you audioholic for recommending two subwoofers to balance bass sound across the room. Before when I had one sub placed at the front, it was too punchy when listening at the front, too boomy at the back and null at the middle. I did try switching phase but no matter the value it sounded the same. But when I placed second sub in my room, I realised phase control for both subs now makes a difference. My room is approximately 10 foot squared and currently placed two subs at the front and back. What I do for phase is first set both sub to zero phase. Then I listen at the front, middle and back. If there is punchy bass at front and back, and null at the middle, set first sub phase from 0 to 180. Then have a listen again. All front, middle and back should now have balanced response. If bass already sound smooth across the room, try switching first sub phase to 180 and hear whether it creates punchy bass at front & back with null at middle. In that case switch back to 0 and leave it. If bass sound quite smooth and switching phase from 0 to 180 didn't make much difference, switch the second sub phase to 90, then go back to first sub and try listening at both phase 0 and 180. I hope this helps for anyone with dual subs and phase control. Note that I only did in my 10 foot squared room and unsure if same solution can work at rectangle or asymmetric room.

Took a while adjusting the gain knob on my subwoofer to get the gain (volume) at 0.0 db through my receiver but finally hit that sweet spot. You guys are great. Thank you for your expertise.

[@duranarts]

This is by far the most useful subwoofer setup video. The explanation is so thorough!

[@CarAudioInc]

I'm big into car audio, so this was interesting to see how the home theater people do subs.

[@getoutofthekitchen]

I learn something every time I watch one of your videos. Thanks for sharing your knowledge.

[@hometheaterenthusiast1566]

I look at you guys as teachers because you are teachers. I appreciate all the information and thank you for sharing.

[@HighwayStrat84]

You guys helped me out with this video. I have a 25+ year old dbx 15inch 250watt floor subwoofer, and just recently the amplifier that went with the sub finally had enough. So now my classic sub cant connect to my pioneer elite receiver because the sub has speaker wire instead of today's plug-ins. So I was able to find a subwoofer amplifier that helped but still after all connecting to amp and receiver, my sub was still popping in and out, until you show to connect the lfe on the amp to the sub ports to the receiver, all is golden now, the subwoofer is a classic and it still shakes and rattles the house

[@TheJimi74]

Great video! But how about floorstanding speakers, should I set them to small or leave them at large...an what crossover frequency should I use with floor standing speakers?

[@ellengriffin5196]

Hi Gene, I am new to Audioholics, great videos, very informative, thanks for doing what you do. Setting up a new home theatre this fall. My room is 24X16X8. From everything I have read or viewed, 2 subs are better than 1, and 4 subs are better than 2. The more subs the easier it is to eq the room and eliminate dead zones. My theater front end will be the PSB Imagine T3 Towers and Imagine C3 Center Channel. All other speakers in the setup will be PSB speakers. When it comes to Subs I am looking to go with either two SVS Ultra PB 1600, or 4 PSB Sub-series 450. The theatre will be a split of 60 % music listening- 40 % Home theatre. All the reviews indicate the two SVS Subs would do a great job below 20HZ whereas the PSB Subs would lack in this area. Having 4 PSB Subs would provide a great presence, but would their be a noticeable difference in performance. All thing equal what would you recommend?

[@denver41]

Dammit, I love you guys! You guys are such a big help in me expanding my "audiophile" evolution. Thanks as always!

[@ericnortan9012]

GO BLUE!

[@TheBinaryWolf]

Thanks for all the good info. If the front and rear speakers lack strength in, say, the 160Hz-200Hz range, would it make sense to raise the cut off level?

[@prayingmantiskung-fu2037]

Yea please do a video on Phase especially dual subwoofer phase ,that would be great. I have two Klipsch R-115SW In opposing corners and the back sub is turned slight off to the right , so both subs were not firing directly at each other

[@Prabhu_njd]

Praying mantis Kung-fu yeah me too.. i also have 2 klipsch r-112sw subs..

[@LFC-Star]

I hope you've the phase set to opposite of each sub.. one a 180 the other to 0.

[@dsertwq]

I've been needing this video for the last twenty years of my adult life.

[@swllz]

Hi, Gene, I improved sound of my PSB 6i subwoofer a lot simply by putting a marble plate (15x17 inch) on top of the subwoofer. It improved the boominess a lot. My sub was tested by Sound&Vision to be a good sub to begin with. The improvement cab easily heard. I have no way to measure it. If you see this message, please try it and measure it in terms of FR and distortion. Thanks,

[@nishalp1747]

Good day guy. Love your show. To comment on on what I found that works for setting up subwoofers (jbl sub 150, Tannoy ts8, Wharfdale whs10e, amp Yamaha rxa 1050): setting amp subwoofer gain to about minus halfway (-5 in rxa1050) and just around 60% power on subwoofer amp. Tried this with all subwoofers and it works extremely well. It also works for different amplifiers as well (tried on Marantz sr5007). What this setting does is use the signal only from the amp and uses the subwoofer amp to adjust volume. This opposes having a high gain in the amp and a medium gain in the subwoofer. To summarize, the lfe on amp is used only for the signal (not a highly amplified signal) and the subwoofer amp generates volume. The subwoofer is not amplifying an already (highly) amplified signal. Just to add that at minus halfway, sub doesn't necessarily cut off.

[@zombeat7376]

What you said makes a lot of sense the sub woofer is better at producing lower frequencies than the speakers and speakers at better at producing the mids and the high frequencies. Tbh I thought I knew best as I have been into cinema sound since the mid 90's and didn't want to deprive my speakers of the lower frequency. Its never sounded better. More powerful sound and damn the channel separation sounds better than ever too. Hats off. Thanks! P. S I have mordaunt short mezzo range and my woofer sounds even better too and just a really nice balance.

[@geraldperry7779]

I miss Marshall, always did good reviews.

[@Davek2sb]

Do you need to use the left and right inputs? I’m using a y-splitter on my subs currently, is this a good or bad thing?

[@Jeff1960G]

Great video, thank you. I have the B&W ASW608 sub I just purchased. I have a Denon 9.2 receiver. Do I connect both "line out" cables to the receiver, or just one? Sorry, new to being an audiophile. I have a B&W 9.1 setup going (2 atmos speakers included) (no amp, just receiver)

[@philiproche1607]

That drawing to your right there - looks like something my daughter drew! She drew and drew and drew and now she's studying at the School of The Art Institute of Chicago.

[@ryanr6240]

What's better, using an spl meter to get all speakers to 75db or to run the AVR correction program?

[@al8603cl]

Good info. One thing I have never ever found discussed anywhere is a more and more common situation where you deal with adding a dedicated sub to a multiple powered tower setup. I would love to hear your input to this situation. I came to realize that while the powered towers were great from a perceived loudness perspective they lacked the deep visceral grunt capability needed for a real punch in the gut perspective that a dedicated sub gives you. So, in my case after listening to many opinions, especially concerning multiple subs. I came to the conclusion that if you have quality powered towers and you want deep down grunt power you do not need multiple subs. What you need to add is a sub that can really dig deep. Set your AV system crossover for it's lower setting. In my case 50hz. This allows the dedicated sub to do its thing and allows the powered towers to do what they do best, that is mid and upper bass. The mid and upper bass frequencies are far more directional and give the same apparent affect as having multiple subs acoustically while the dedicated sub handles the deep bass grunt work whose frequencies are far far less directional. This is my opinion and observation on this more and more common consumer situation. I would love your opinion on this subject. As I said, a great many people buy powered towers thinking that they are an ultimate package only later to realize they are great but, they do not give you the deep powerful low level punch that many people really want. Especially when watching SciFi or action flicks.

[@Audioholics]

This sounds like a good setup but there are a couple of concerns: 1. you will truncate the LFE signal to the sub if your processor doesn't have a separate LFE crossover setting, 2. You lose some of the benefits of multi-sub modal averaging since all of the bass sources are not covering the exact same frequency bandwidth. See: kzbin.info/www/bejne/aniqZIqle9Rsh5o

[@al8603cl]

Thanks for the reply and attachment I appreciate it. My AV Receiver has LFE crossover settings. I set it at 50hz. I agree with the multi-sub modal comment but, I believe that this is minimized to an extent with the fact that I have 4 powered towers for mains and rears and they are all emanating the same frequencies above 50hz where most of the content is and, as freqs below 50hz are largely non directional I believe it a very close approximation of a multi sub setup.

[@Audioholics]

Yes 4 powered towers will give you some of the benefit of modal averaging, but you do lose it some of it with the sub operating below 50Hz which may or may not be a problem. Non-directional does NOT mean modal properties are to be ignored. It's best if you pull some in-room measurements at your listening positions to see what's going on.

[@al8603cl]

I have down loaded a few bass tone generators. And, I went to my local Shack and bought a db meter. I have 4 DefTech BP9040's powered towers 300 watts per tower to the built-in subs and an SC8000. I have adjusted to the powered towers and the sub to output an even sound level so that the sub is not over powering the towers and so that the towers sound pleasing to my ear at the various freqs that the tone generator is generating from 20hz to 120hz. Am I missing anything? Is this sufficient? Or is there something I am missing completely that you would recommend?

[@BTinHD]

thanks...I realised I had not switched my subwoofer cross over to bypass....it made a big difference to the bass...thanks for the good information

[@michaelzoran]

PHASE QUESTION: I often hear people ask, "Should I have my subwoofer set at 0 Phase or 180 Phase." This is an important question and I understand the logic behind it. If it was simply a matter of a Phase switch on a subwoofer, the answer would be fine - there would be only two possible choices (0 or 180). However, it is not that simple. My A/V Receivers from Onkyo and Sony allow me to select 0 or 180. This means there are FOUR possible scenarios. Those scenarios are: AV Receiver = 0 and Subwoofer = 0 AV Receiver = 0 and Subwoofer = 180 AV Receiver = 180 and Subwoofer = 0 AV Receiver = 180 and Subwoofer = 180 I fully understand that if you have your subwoofer in the front of the room, you should have both the A/V Receiver set at 0 and the Subwoofer set at 0. However, my confusion and question relates to when the subwoofer is in the back of the room. I know by subwoofer should be at 180 Phase. ... However, does this mean BOTH the A/V Receiver and the Subwoofer should be set at 180? Or does this mean only ONE of them should be set at 180? In other words, I'm asking if you want the Subwoofer set at 180, does that mean the A/V Receiver also needs to be set at 180? If not, does this mean placing both the A/V Receiver at 180 and the Subwoofer at 180 will create a form of 360 Phase? If you could explain this, I would appreciate it.

[@cornerspeed92]

Great video, it seems like your talking more home theater then home HIFI. Just bought a 400 watt KLIPSCH, my Yamaha has one (subwoffer) out RCA jack. Im lost on the L/LFE is that for home theater or home HIFI? I received one RCA cable, and bought one single cable, which do I use?

[@hilldog3450]

I just adjusted my RSL Speedwoofers controls with help from this video. Thank you!! P.S. I bought the Speedwoofer based off of your review, and it has been literally unbelievable. As musical as it is capable for home theater...

[@samsquanch67]

Good video! So in my case running a 2 channel through an amp and preamp probably don’t want to use the LFE rather use rca’s sub out to sub in on the sub correct?

[@vinu_varghese]

Nice, thanks for the hint on the subwoofer level, I used to set the gain level on the subwoofer to the 12 0 clock position and have audyssey run through to - I wasn't much concerned with the subwoofer level audyssey setted. After watching your video, I looked at the level - and it was -10 db, So I adjusted the gain on subwoofer and managed to get back to -3 db :) and woohoo, my bass levels are way much better now :) - thanks guys

[@dsertwq]

I'm trying to run two powered subwoofers from one line out. The subs don't have line outs. Is my best option to use a Y cable and hook them up to the LFE in? Thanks for the video!

[@Fotoklasika]

I set all speakers crossover to 80hz, LFE 120hz. What about subwoofer manual filter setting? 50-150hz... I set 80hz on it too. Others set to maximum 150hz (or more if subwoofer support) .Thank you!

[@myonedog]

Hello, I’m confused, I have 2 subwoofers that I set both of the crossover to the max which is 120hz- for my receiver do I put the crossover to 80hz or 120hz ?

[@codyharris1521]

I was thinking about upgrading from 5.1 to 5.2, I currently am running a Polk 12' subwoofer. Should I have a smaller subwoofer on the other side or keep purchase another 12' subwoofer....

[@garyausten5939]

Do you know, on a Denon X4700H if you can automatically set it up so that music will play at a lower sub boost than movies (not adjust the volume manually whenever the change occurs)?

[@moviestarsnake]

If I ran the calibration on my Pioneer Elite, and then switched the phase on my subwoofer from 0 to 180 because the 180 provided better bass, do I have the rerun the calibration? So that it can calibrate according to the 180 setting?

[@MR_CEO]

I just set all my speaker levels to 0 on my Yamaha Amp, my subs set to 50%. Crossover on my receiver is 80hz and the subs crossover is set to maximum. works for me 🤷🏼‍♂️🤙🏻

[@user-ff1kd6fe5k]

You guys are amazing. Setting up the sub was so hard until i saw this. Great double act

[@mccarthyd6603]

Help!!! Just watched the video and I am confused? I thought you were suppose to increase the subwoofer crossover to the max only on the setup? On my Yamaha I set the crossover to the max when I initialized the Ypao... after adjusting I then set the speakers to small ( B&W M-1) then adjusted the crossover on my Yamaha to 80 Hz AND my Sub also to 80 Hz.....do I need to keep my Sub at 150 Hz all the time? It sounds great now but not sure if I need to increase the Hz on my Sub to the max all the time going forward? Thanks for the recommendation from the experts on this...love the channel by the way and just subbed 👍😍

[@josefermalino461]

Very informative guys it helps me a lot as a beginner audiophile 👌

[@SwirlingDragonMist]

Also, consider your sub's frequency response relative to your other speakers. Some smaller subs only go down to the mid 30's hz, which may be on par with your stereo mains in a surround system. If the sub has similar bass extension to other speakers present, the Audioholic may want to consider running all 3, or just 2, or just 1 depending on how much bass energy their tastes desire and their acoustics support. Typically more subs are better as they give better seat to seat consistency, and obviously the solution is to upgrade the sub to have extension over the full bandwidth. But if they're all have similar extension, a well crafted floor standing speaker will have a pretty smooth crossover, and adding in a solo woofer to the party may go totally cool-aid man on your low end. :D OH YEAH!

[@centauro74]

I have a SVS subwoofer, it has red (LFE) and white inputs, when I use a splitter the output of the sub gain 6db. Does the crossover from the receiver still works like that?

[@felixsantosmolina8872]

Hi audioholics, I would like to know if I can use Bose redline single cubes with the Pioneer Elite VSX-LX101 and should I connect them to the receiver.I also have the powered Acoustimass 9 sub unit.Any info would be greatly appreciated.

[@tommytippietoes882]

I’m using a SVS sub in a music Hifi situation with a stereo receiver which doesn’t have ANY of the options you’ve mentioned for setup. How do I properly set it up with a stereo amp (AXR100)

[@DBTAudio]

Gene, I have Marantz 7702 Mk2 & just purchased a Sunfire HRS-12 sub. My new sub keeps going into standby mode after about 20 minutes of playing and the LFE signals are definitely being played in the content I’m watching. The sub will not turn back on until I unplug it and fire it back up. I've increased the sub level in my Marantz to boost the LFE signal to the sub and it continues to go into standby mode. I just got setup Friday night and plan to call Sunfire on Tuesday after Memorial Day for tech support. Any advise is truly appreciated.

[@JoeWilly69]

So I'm watching this video for the first time and I just bought 2 me subwoofers, my Denon has crossover settings and this confuses me cause I can't see the exact numbers on the sub there's just incremental lines. I have floor standing speakers that go down to 20hz so idk if it's overkill but I wanna try and get this right. Until now, I haven't really addressed this and I think things sounds good. Anyway, if u can dumb this down for me I'd really appreciate it.

[@randyhunt1581]

Hey guys I have a small delimma. I purchased a polk audio CS1 series II center speaker when I first started putting together my home theater system. Not knowing about timber match at the time I then purchased a a pair of fluance signature series bookshelf speakers. I love my fluance speakers so Im keeping them. My question is would it be worth buying the fluance center speaker to match timber or stay with my polk audio center? My finances are fixed at a horrible low. I live alone and Im 62 years old. It would be very difficult to replace the center speaker at my income level but if it would make that much diference I would. I could try to sell my polk, it is in excellant condition. Please respond. Thank you very much. I love your videos, they are very informing.

Hey guys great video , just bought a Martin Logan 5.1 set up , motion 4 (front) motion 8 (center) motion 2 (rears) dynamo 700 sub .. Denon avrx1300 receiver .. those speakers are rated at 4ohms , the receiver gives you an option to change the ohms load , from 8-6-4 .. should I change it to 4 ohms to match the speakers ? And is that receiver strong enough to get the most out of those speakers ? All the crossovers are set at 80 hertz , thanks for the help

[@thomashoctor8687]

Jose Rivera Nope. Leave it at the default 8 ohm setting. All it will do is choke off the receivers power supply to change the setting. Best to just monitor your listening levels and maybe set a maximum volume setting within the receivers audio settings and rely on it's built in protection circuits if there's any issues.

Ive been running a 7.0 surround setup for about two years now and so far no major complaints. All speakers are run full range except for the center with is at 60hz hp. Ive done comparison tests with subs set at 80hz for all and full range without subs. I couldnt rell the difference. I would like to run my subs but im not a fan of the 80hz xover point for all speakers. If i ever change to a lower setting for subs and lcr i lose bass like the processor isnt sending it out to the speakers. Definitely not a cancellation issue. It just gets lost in the mix and never making it to the speakers. I would like to pull my subs out of storage and put them to good use and was wondering if you had any recommendations as to settings in the Marantz i could make to help with disappearing bass. Ive tried lfe+main with no difference. You may think im alittle nutty when you get to my center channel setup but it sounds phenomenal.

[@stevenmichael7770]

I've heard you say set them all to small and set the crossovers to 80Hz a bunch of times, but what does setting them to small actually do? What is the receiver actually doing with the low frequencies and how does it tie in with LFE + Main? I understand LFE, but not sure what's actually happening when you change the speaker size setting. On an older Denon I had, it would automatically set the crossover and send all the low frequencies to the sub when they were set to small, but it didn't have crossover settings in the menu. With the ability to set the crossovers separately what does the size setting accomplish? Thanks for all the great informational videos!

[@jamotter8967]

What is your advice for a subwoofer purchaser who connects the sub to an integrated amp with a SW port, but no subwoofer crossover fintion in the int amp. You said that going into the sub via the LFE port would disable the sub's built-in crossover funtion. How then would I connect the sub to the int amp to enable the sub crossover to work? Someone please advise.

[@MattyDante]

I have a Klipsch SPL-120 it has positive and negative analog inputs. My amplifier has only a single pre out analog female receiver. Should I only do a single analog cable to my subwoofer into the left channel only, or do a Y splitter that utilities positive and negative inputs on the sub and only the single sub pre out on the amp?

[@bobinocencio4314]

Hi Gene. My home, when it was built 15 years ago, was pre-wired for 7.1. The builder used coax cable to handle the subwoofer which has coax-to-RCA converters at either end to make my connections. I purchased a 2nd subwoofer less than a year ago and had to use a Y connector to hit both subs. I now have recently purchased an Anthem AVR 60 which has two subwoofer outs but I am only using only one of them because of my current wiring. My question is, would it be worth the effort for me to re-wire, getting rid of the coax and replacing it with two subwoofer cables? Thanks!

[@thomashoctor8687]

Bob Inocencio Only if the Anthem's sub pre amp outputs are truly independent and capable of setting separate levels and distances. If not it's just an additional mono line out and the splitters are fine.

[@new-knowledge8040]

WOW, what an improvement. In my apartment, the low end frequencies from the two speakers was cancelling out due to the shape of the room. So I had to switch the polarity of the woofer in one speaker to fix the problem. Fortunately when I built my speakers, I added 2 switches per speaker box to reverse the polarity of both the mid-range speakers, and/or the tweeters. So I set them in the 180 polarity reverse position, and then reversed the polarity of the wires hooked up to the speaker box.

[@peterbooth6753]

I've literally been trying different stuff with my subwoofer for like 3/4 years now. Done every trick from every video, placed it everywhere in the room. But I just can't get that damm sound I want from it. It always sounds so uneven. In some parts (for exempel a movie) I can't hear anything from my subwoofer, not even a little. But in other parts it feels like it's going to blow up. I never get that smooth bass that feels like it covers everything, from voices, to music, to the gun and explosion sounds. And sub and speaker are actually pretty decent. I've heard them in action by others and it sounds great (almost the same space as the room I use it in). Maybe one day I wil get that sweet, sweet sound!

Awsome!!! I just found out why my onkyo reciever was setting up my subwoofer at -15 db!!! Thanks guys!!!

[@koolkiwikat]

I have 2 Polk Audio PSW110 subs and 2 choices of setup, corner stack them one on the other, or side by side of my TV next to my main towers(Polk Audio RTIA9's) Whats the best option for both music and movies?

[@scottb721]

Just adjust the x-over in my avr down to 80hz. I noticed the sub level is set to -3.5db. Should I bother rerunning Audyssey for that ?

[@TheCoyote1984]

Wich is the best setting for a polk psw505 12"

[@donriddle8393]

I want to connect a powered subwoofer to my desktop, MB: Gigabyte GA-X99-Phoenix SLI (rev. 1.0). The MB has 115dB SNR HD Audio with Built-in Rear Audio Amplifier. The connector for the subwoofer is a 3.5mm connection. What type of wiring and connection do you suggest? Stereo 3.5mm or Mono 3.5mm to a RCA subwoofer cable?

Hello guys. These may be dumb questions after watching this video, but I just want to be sure I'm getting the most out of my equipment set up. So I have a Sony STR-DE625 teamed with a Polk PSW10 (sub) and JBL N26 (sats). Presently, I have a single RCA cable going from the top "WOOFER AUDIO OUT" (there are two both black and not labeled L/R) to an RCA splitter and into both labeled L/R inputs on the sub. This sounds okay, but 1) should I just be using one RCA stereo cable to connect both woofer outputs to both sub inputs? 2) or should I use mono cable to connect one woofer out to the white L input on the sub? 3) Does having two woofer outputs on this receiver make it 5.2 channel? 3) There's no LFE on the sub nor any switch to bypass the crossover. What should my variable crossover setting be? Thank you for any help you can offer.

[@davekunath4113]

I have a very simple question. I have a 7.1 AVR, but it allows you to connect two subwoofers. Based on the documentation, both subs are supposed to get the same signal. My question is this: Do you keep both subs at the same phase or do you have one of them 180 degrees out? Thanks in Advance.

Really enjoyed your video. I'm setting up a system (Sony STR-DN1060, Old JBL Studio Series speakers and subwoofer) and noticed a distinct difference when setting sub level on auto-cal as compared to test tones. Level sub with pink noise test tone to the other speakers, and the AVR setting comes out close to zero with the sub volume at half-way. Meanwhile you hear very little bass for real-world listening. With auto-cal, a series of low tones are used (no pink) and the AVR sub-level comes out at about +10db, and the base sounds good. Learned this a while back using the Avia DVD that pink noise doesn't work for sub-level. Lot of Googling and I don't see that mentioned very often.

[@dr.tissonjob5707]

Do you recommend y splitter subwoofer cable? Does it cause too much a load on the receiver or subwoofer?

[@Audioholics]

I would only split once. Daisy chain or get a buffered mdsp box to split a single sub out to 4 independent sub outs.

[@dr.tissonjob5707]

@@Audioholics So if there are 2 subwoofer outs, we can use a y splitter cable from the two outs to the 2 separate subwoofers?

[@DIPDISCOVERER]

Sir, I have Denon AVR model : AVR-S650H which has two subwoofer output, i have purchased subwoofer PSW10 from Polk Audio and this has no LFE input, this has L & R, so kindly advise how to connect my speakers (Speakers Front-Large, Centre & Surround-Small) , if i connect the sub by wire from AV receiver L & R point to my sub L & R input and output from sub to front L & R without RCA cable connection, then what is correct way ? kindly confirm

[@ianwalton7893]

Hi guys. I've had my gear a long time now. It's been with me through three properties, so is quite dated now, but still works well enough. I probably need to set it up again. I have a Yamaha DSP AX2 amp and a Paradigm servo X15 subwoofer, which is an absolute monster. The sub comes with a separate cross over unit which has phase, cut off, and level control knobs. I have always set the cut off at 80hz. Are you saying this is wrong and works against the amps LLF output? Should I be setting this up at max and letting the amp decide what frequencies go to the sub? Cheers guy's.

[@christophercarr6023]

Hey guys, another excellent video! My sub have stereo inputs and my receiver have dual sub outputs. I have only one sub, should I run a stereo RCA cable from the receiver to the sub or should I run a mono cable?

[@thomashoctor8687]

Christopher Carr Mono cable from the subwoofer pre out to usually the left line level RCA input or the one that has LFE or mono written on it. If not it's usually the left one I believe. The stereo inputs are for those using a 2 channel stereo receiver where the sub sums the bass coming from both the left and right speaker's attached to the stereo receiver.

[@Edsel76]

Hi guys, I have a home theater in a box receiver, so it dose not have an LFE out of a RCA line out the subwoofer it came with is passive. And I just bough an active sub polk paw 10 ...So do I connect the left and right speaker wire to the powered sub high in put or can I just use the passive sub output of the receiver?

[@markmorgenstern]

Hi guys! thank you for the video! Seeing you with a removed amp from a self-powered sub makes me think I should ask you this: I have an issue with receiving RF on my sub (I live in direct line of sight of my city's main antennae) and I've tried everything: balance XLR cable, pads, etc. I even disassembled one active speaker and built a little internal Faraday cage around the amp, which helped, but not enough. My next step is to totally remove the amp, as you have, and either put it in a metal box or just run the sub passively with an external, normal (i.e. in its own metal box) amplifier. Is this my only way out? or should I plaster the inside of my sub with tin foil? Any advice appreciated. (My sub is an Energy ES-18XL, which does not happen to have the convenient passive binding posts the one in your video has) Thank you!

[@dustang05]

For what its worth. I really enjoy the videos and keep up the great work you do. I am always looking forward to your next video. Maybe expand a little for us video files. Thanks.

[@TheHitmanAgent]

I have a dilemma. In my 5.1 home theatre system the center speaker is a Dynavoice Challenger c-5 mk1, and I recently noticed that out of the two 5.25inch woofers one sounds louder than the other (even tried swapping them, same problem). Why is this happening? The speaker receives the a mono signal from the AV receiver (LFE) so there is no problem with the balance. Or maybe the passive crossover in the speaker is faulty somehow. Please, what should I do?

[@Danielm316]

Thanks for sharing your expertise with all of us. I have a subwoofer and I can hear a radio station going through it how do I cancel that is possible that is coming from receiver or subs some how pick up radio frequency on their own ? Please help me out

[@mattk8019]

QUESTION... DOES ANYBODY KNOW WHEN THE 2017 RECEIVERS ARE ANNOUNCED? Iam curious & wondering if it's wise to hold off for a couple months... Iam considering marantz, Yamaha, denon or even pioneer. Do they come out around about the same time?

[@titotabuquilde8218]

Hi sir Audioholic me I ask you, how can I connect of my old sony DVD player (no hdmi port) to my new yamaha rxv6a? Thank you for your response ❤🙏

[@Audioholics]

Use the component or composite video for video and toslink or coax for audio.

@@Audioholics Thank you so much sir ❤🙏

[@velocci6666]

Great video guys. Is there an equivalent video but for the AVR side?

[@cristiantolbaru7153]

Hello guys! How about the integrated stereo amplifier with only preouts or dedicated Subwoofer out, as the Yamaha A-S801 you reviewed some years ago. Should this be connected in the LFE of th sub or use a Y cable and connect it to the line level of the sub? Also, will the signal of the Yamaha sub out be strong enough to connect via a splitter two subs? Thanks and waiting for more great videos!

[@unknownkosmos1822]

I need serious answer which one is better???? svs sb16 ultra or svs pb16 ultra for huge loud and no limit bass.

[@SIMPLEXVERITAS]

Hi folks! I´ve a reciever Denon Avr-s 940H and two subwoofers Kliptsch R-115SW. I have each one connected independently to the receiver. I´m wondering why on the reciever shows only one soobwoofer as if the other one does not exist. ? All the others speakers are showing correctly. Thank you.

[@Methodical2]

I need clarification. If you are using the subwoofer preamp out from AVR to the sub's LFE, you must always turn the crossover dial on the subwoofer far right (i.e. 200hz) to avoid doubling the crossover points, correct? What's the difference between LFE filtered and LFE unfiltered? Thanks

[@manoroid1]

I have a def tech supercube 4000 and an onkyo tx-nr708 receiver with audessey. The software asks me to turn the volume up on the sub to 75 db before starting the calibration. It's confusing which way to go about this. The max volume is 40 on the sub. When matching the 75db it reads at volume 3. But I've read starting at 50% this is a huge difference in volume when calibrating both times. Which is more correct way? Thanks

[@arashjahn]

I have a passive sub setup in a sonotube with two JLw6 10's in it hooked up to a Butt Kicker BKA1000N. Both the filters are on, the crossover dial is set to 60Hz, Volume at 4 of 10, and the Onkyo pre-pre had its Audessey set the gain to -10.5dB. After watching the video, it seems the settings are off. Any suggestions ?

[@黄凯文-b9u]

Thank you all. Question can I connect 2 sub in to one sub out put of my avr reciever,?

[@scottsmith8546]

I wouldn't do that, instead just plug one sub into the receiver and the other into the sub you just plugged in...providing it has a line out on that sub. If not than, you have to use a "Y" cable, where you plug the single end into the receiver and then the two subs into each end of the other two RCA plugs on the "Y" cable.
