Making 2 Subs work best

[jabaker]

I have the reference series RF -35 as mains,RB-35 as surrounds and RC 35 as center channel.I also have the Rw12 sub by Klipsch.It is placed toward the front of the room along the side/the mains are placed beside the TV/components angled in the corner leaving alot of wasted space behind the TV/components.I have a second sub,a Kenwood 100 watt sub that I was thinking about hooking up also to my Onkyo 701 and placing behind my Rear projection TV.My Question:What would make my system sound best?

I think just the Klipsch in the corner should be fine. There is not much to gain by adding a smaller sub to do the same as the big one you already have. You can actually hurt your sound worse if the subs are out a phase at certian frequencues, and the room nodes and nulls will also be affected(maybe good maybe bad). But if you choose to run two subs here are two articles that will help you alot.

I hope those help. another easy method is to put the sub where you sit, prop it up to head level, and then crawl on the floor to see where the sound is best. You will look like a fool to anyone watching, but it will definitely sound good when you put the sub in the proper place. Good luck.

The Kenwood will probably bottom out before your Klipsch reaches its capacity... so it may actually limit rather than extend your systems capacity.

If you absolutely want to use both subs, the easiest way to avoid cancellations is to simply stack them in a corner. cjgeracis stacked SVS from current thread
