I'm already running a Polk 450 sub out from a Denon AVR 3801, and tonight I decided to take advantage of Polk's offer to buy a PSW250 at a closeout price (it's being discontinued). My plan is to run the 250 in conjunction with the 450 -- I'm a bass freak anyway, and I think it'll help beef up movie soundtrack listening in particular. But a few questions for you wizards before the new sub arrives:
1. I was thinking of just setting the 250 atop the 450 to conserve space in the room, but is that a bad idea? If not, why not? These things are made to shake anyway, right? Could it hurt to mount the smaller 250 on top of the larger 450? And should I put a slab of something between them? If I don't mount them one atop the other, what's a better solution from an acoustic standpoint? On different walls? Same wal, firing same direction? My 450 now fires out at me, same direction as my front LRs.
2. I'm going to have to split the LFE out between the two subs. I know some of you are doing this. What kind of splitter are you using, and where did you get it?
3. Speaking of splitting the signal, in your experiences, has their been any signal degradation from doing that? Anything to keep in mind while running two subs?
I guess that's about it. Thanks in advance for your input.
