More likely than not putting your subs under your front speakers will have them in less than ideal locations. To find the best location to place your subs you would want to do a sub crawl. Basically just try different positions around the room until you find the place that sounds the best. Then run Audyssey and set your crossover to 80hz for all speakers.
Setting your crossover to 80hz will not leave your speaker's potential unused. A crossover of 80hz will put less of a burden on your receiver and speakers, allowing them to play easier when not trying to play the full frequency spectrum.
You are using a subwoofer cable from your receiver's LFE out right?
That's what I thought. I took them off the subs yesterday and turned the subs back to sit in their natural alignment. I also discovered he had the subs volume set to full on both subs, when we ran the auddesey, where as it suggestions during calibration to have both set at 50 %. Oh well, I've moved them to basically the 1/4 position on the front wall like so:
The dimensions of the room don't quite allow for corner placement of the subs, as this would necessitate moving my fronts closer towards eachother, thus ruining the equilateral triangle I've got going ( 8.5 x 8.5 x 8.5 ).. also making for some pretty boomy bass in a small to medium room from what I understand. He actually used some old rca cable I had lying around for the second sub, it IS plugged in to the LFE for what it's worth, though for some strange reason my old sub ( the one on the left in the picture ) sounds lounder then the new sub when both are set to 50 %. I don't know if this is strictly a matter of room acoustics, or the old sub IS actually 100 watts rms as spec'd, where as the new one is 55 RMS with a 255 peak... I suppose it might be the old cable he used? here's a picture of it just to be sure:
I've double checked them, and he's got what I guess I would do with those cables, which is run the actual sub cable ( that came with the denon ) out from the receiver into the back the white rca plug, then have it plugged in to the right sub, and run the other end of the rca cable into the other sub w/ the white rca plug on the other end. In any case I don't have a spl meter, but do have a unscientific android phone, and dl'd a sound meter program to get a vague idea just to see if it was my imagination or not, but indeed the old sub was about 5 - 6 db louder then the new one, so I turned up the new a few notches until they both were at about 83 db .. Of course who knows if that is any where near accurate, but at least it seemed to allow me to set them at the SAME level. Auddesey only measures the sound of " the subwoofer ", it doesn't know that there are two of them, as the receiver is a 7.1 not a 7.2, and there's no setting to change that, so I've got to make due.
So I guess the next step would be what, getting a longer cable possibly and moving the second sub elsewhere?
By the way, I've got my Denon up on Kijiji and Craigslist, and if I can get 100 bucks for it will sink another 100 or so into another used Klipsch of the same model just to make things easier.
