I am on the fence between getting two H-100's or the CSX-15". I can get the CSX-15 cheaper than the two H-100's but I have a large room, 25x25x11' sloped ceilings. I am pairing this with a Klipsch Synergy F-3 system. I am worried that the Cadence will not fill the room on the one end and worried the BIC will not go low enough on the other. I considered a eD A2-300 but do not like the wait and feel these offer me the best options for the dollars. With the live.com discount the dual H-100's will not cost but around $400.00 shipped.

I have read alot of threads and there is no consensus on which is better. I just wonder if the Cadence is a big enough upgrade over two H-100's.

Please give my your opinions.

As a former BIC h-100 owner(which I am now selling) I can't give the sub enough props. It is amazing for the price and I was more than happy with it. It gets low and puts out some damn good sound. I would guess 2 of them would easily outmatch the CSX-15 and give you some nice room filling lows. Only reason I'm selling mine is that I got an Aperion setup in cherry color and opted to go with a Bravus 12D to match the rest of the system. The h-100 did me VERY well though.

With your room size, I would go for the dual BIC H-100s. 25' x 25' x 11' is pretty hard to fill with just one sub.
