ok is there a big difference if connecting two sub's, since my receiver has two sub inputs would i really notice? http://talk.dvdtalk.com/ubb/confused.gif

Two sub inputs? for output two subwoofer?
Maybe that's for accept other decoder's output, such as DTS or later format.

If you have them spaced & turned so that they don't interfere with each other, then yes it does sound good. Once you get the sound waves not bouning off each other then it sounds great. It's not hard to do, just requires some time & a movie with noticeable bass.

Unless your room is huge, I doubt that you need 2 subs. And as edwardsc pointed out, it's tricky to do so they don't interfere with each other. Have pity on the neighbors http://talk.dvdtalk.com/ubb/smile.gif

I have two Carver subs and I must say the difference between one vs. two is tremendous. My brother found this out first hand. His system was similar to mine and sounded ok. His 200 watt sub seemed not to fill his room so I encouraged him to go and get a second one. I have to say he is more than pleased with decision. His room now shakes. When I use both of them, I have the amp level set to 1/2 on each. My room is much smaller than his, but the bass is much fuller with the two subs. I have placed them in opposite corners and have a sony receiver with two sub outputs.

joechaos, I take it you have no termites http://talk.dvdtalk.com/ubb/smile.gif

I have seen a friend try this before but didn't see a huge difference. Maybe we were doing it wrong. They were certainly not Carvers.

I have 2 subs, and they sound cleaner than
1 because they can each be set at a lower
output level to maintain the same SPL in
the room.

They also move twice the air, and have
greater impact than just 1 unit -- the output
difference is huge.

If you have 2 subs, it's preferable to have them be front firing subs stacked on top of one another to avoid the cancellation effects.

My Sony DB930 receiver has 2 LFE/sub preamp outputs too.

Anyone know if you can use an RCA Y adapter to hook up two subs to one preout and still get a good signal? I have done this before with a mono VCR to a stereo receiver, so in theory it should work.

If you can keep the subs close together and on the same plane then you should be able to avoid almost all cancelation effects. It does suck if you aren't carefull with where you place the extra sub. I know my roomate and I were using 2 Cambridge 12" subs a few years back and they were in opposite sides of the room. Some spots in the room sounded great and in some spots you couldn't feel a thing (destructive interference sucks, damn physics). When you set up your subs be sure to check how it sounds from lots of different listening positions, or you may have the same problem.

hey thanks all, i guess i'l try it if i can't get it right i'll just put the other sub in the living room.

This will work fine, for HT (since the .1 is
mono anyway). But for music, mono bass is
a mess, so make sure you only plan to do
this for HT.
