sub opinions

[Suave]

Reading this thread sure makes a dual subwoofer setup appealilng...! My problem is that I simply don't have enough space for two subwoofers in my room. However in the pursuit of better bass performance, I am upgrading my 10-inch SVS PB10-NSD sub to a 12-inch Axiom Audio EP500 v2 sub (I ordered it last week) - http://www.axiomaudio.com/ep500.html. The new subwoofer is said to extend all the way down to 18 Hz thanks to its sophisticated on-board DSP chip.

tkroeker - as far as I know most (if not all) AV receivers have only one subwoofer output. To connect two subwoofers, they must be daisy chained (i.e. at least one subwoofer must have an output). Am I saying this correctly Brad?

i imagine some receiver, somewhere, might have 2 dedicated sub outs...mine doesn't though. mine are chained..

I just joined the frey in Dual Sub's in a small room (Mine is 26' x 11') and its awesome. My main speaker tower's are homebrew skinny's with a ported 2.5 way dual 5.25" bass/mid-bass drivers below an aluminum tweeter. My subs are Rockford Fosgate 10" subs in a 1.4 cu. ported boxes (downward firing).

Now I can get to 30Hz clean but after that things tend to fall apart rather rapidly by design. If you stand in the back corner of the room, the bass is what I 'd describe as "headachy". My placement of the subs when sitting on the sofa doesn't give this "effect". Bass occurs when needed and I've tried my best to blend the subs into the towers and not overwhelm them.

I'll upload my setup ASAP.

Congrats on joining the "dual sub club"! This thread certainly makes it sound attractive although unfortunately, I don't really have the space to house two subs. I recently upgraded to an Axiom EP500 subwoofer however which plays clean all the way down to 17 Hz and I'm loving the sound.

I'd love to see a pic of your setup when you get a chace to post it on the forum!

damn, you guys are making me want to set up my old dual setup just so I can be part of the club

...unfortunately, I don't really have the space to house two subs.

neither do i..thats what makes it so much more awesome! hahaha

In my old setup, I used two of my subs for stereo bass on the front channels. I really don't have anything technical to say about it because I'm not as tech-y on the audio side of things... When listening, I prefer it over one sub (I used one sub for my LFE but found it annoyingly directional in the place I had it). Because my system is all connected with balanced XLR, I had the subs connected in a rather unorthodox way... Main channels were fed full range XLR (the Dunlavy SC-IV/a speakers are full range) and on the single-ended outputs of the preamp I connected a Mirage LFX-3 3-channel crossover and then out to the subs... so the low end was piped to the subs whenever I wanted some extra boom. I turned it on for low bass music... but for classical/classic rock, etc. I kept it off and ran the speakers full range. I did the same for the rear channels for home theater...

...in the end I believe 2 subs are much better than one.

You may want to try the corners as that may smooth out and extend the response. Best way to figure it out scientifically would be with low freq tones and an SPL meter. The room will typically dominate the response in the 50-60 Hz and 100-120Hz region. Adjusting the phase and using the corners may help you get the most out of your setup.
