So for my particluar set up with the Denon 4802 and room size which makes the most sense? About the same price. I guess the Infinity E250P is out as the second Sub, correct?
If it's in good shape then sell it on our classified area. If you need help sizing up it's value let me know.
For home theater 1 sub can work just fine in most home theaters if you plan to use the crawl test for placement. Placement is everything for subs.
I suggest getting the biggest sub allowed for home theater for the low effects. The Ultra would be an excellent choice IMO.
Don't plug the ports though.
My reasons
1. Low stuff isn't audible
2. Low stuff is already boosted by your room.
3. Upper bass is more important and far more common than the really low stuff.
4. Plugging them will cause chuffing for low frequencies
Someone here recently unplugged the ports and discovered it sounded better. Can't remember who, but it was someone with an SVS sub.
Make sure you get up some photos of your setup in our member systems gallery.
