Subwoofer help with Deep BASS!!

[ocielz]

I need some help getting the Best DEEP BASS from my Polk PSW505 SUB. I have it connected to an Onkyo TX-SR608
Speaker Setting on the receiver LPF to LFE is 120Hz
The sub has the following settings and Nobs
Phase 0% to 180% - I have it at 0%(dont know much about this setting)
Volume - 75%
Low Pass(Hz) - 60/90/120 (I have it between 90 and 120
LFE IN (Unfiltered)

I need help with the settings that are in Bold.
Any help would be appreciated

Set the low pass filter to the top - 120Hz- so that the sub will play whatever the receiver sends it. Anything you filter out at the sub will simply be thrown away.

Volume must be set in conjunction with the output level of the sub channel from the receiver. The sub should play at the same level, or a few dBs higher, than the other channels. You need an SPL meter to measure that or a receiver with a mic and auto calibration software.

Phase is either in or out in relation to the other woofers in your system. Play music with lots if bass and listen to it. Then shift the phase by 180 and listen again. The out of phase position will cancel some of the bass.

Thanks for the input I will tinker with it today

That is so strange! I have a PSW 505 as well AND I have an Onkyo TX-NR709 and I have the same problem! In my situation though, I have two Polk Audio LSi 15 fronts and they have built in subwoofers. They aren't powered subwoofers though, but the receiver picks them up (I guess) and it says that I have two subwoofers in the front, but only my PSW 505 is hooked up to the Subwoofer output on the reciever. I think for that reason, it's throwing the sound off. I may be completely wrong, but I have some awesome speakers, imo, and I just don't feel like they are putting out the best quality sound that they can put out. Hopefully that makes sense, but something just isn't right. Granted I do the automatic setup with the receiver and it sets all the speakers to really low decibel levels. So much, in fact, that I go in afterwards and adjust them. I dunno, any input would be a great help.

Same thing since happens to me when I run the Odyssey set up. I have to raise the volume on each speaker up to a couple Db more. The sub is the one that gets really low, into the Negatives (-13/-14)

I moved the settings on the Sub and now it sounds louder...... But it can't handle the Deep Bass from War of the World's (Tripods emerging) or the somersault from Iron Hide in Transformers. It Buckles(?) with all the bass coming out, I still have to find the perfect volume Level. Where it will handle the Bass perfectly.

If you mean your subwoofer is clipping, that probably means that your equalization isn't correct, or the volume of the sub is too high. More isn't always better.

That's the word I was looking for, Clipping.

Find the bluray you have with the heaviest bass and dial down the volume of your subwoofer until it stops clipping. That level is as much as your sub will produce. You don't want "boom boom" bass all the time... just when the movie calls for it.

Thanks for the info.
Time to do some more tinkering
