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.

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?

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.

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

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.

Great video and you did touch on subs not turning on from auto mode.Well mine does not.I have an SVS SB 12 sub and a Yamaha receiver(673)and I cant get sub out of auto mode.I used YPAO to set up my theater putting the sub at half gain and the results set the sub at minus 0.5 which I felt was pretty accurate. So what can I do to get this sub out of off mode? Should I raise subwoofer trim level?

@SwirlingDragonMist 7 жыл бұрын

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!

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!

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
