I'm finishing up my install and I think my sub is not big enough for the room. I brought it up with the HT dealer but he thought it would be plenty. I'm not sure if I'm just used to "too much bass" or if the sub is actually not moving enough air for this size room. The options are to buy another Sub 10(cheapest) or sell the first Sub 10 and buy a Sub 12 or maybe a 15. What do y'all think?
The reason I feel like it is too small is there is I can't really "feel" the bass. I can if I turn the overall room volume way up but it doesn't seem balanced at lower volumes. I move the power knob up from the factory 50% to about 80% last night but haven't had enough time to test thoroughly. This system is used exclusively for movie/TV.
While I'm not too familiar with the performance of a Sub 10, two subs is generally better than one to really smooth out the room response (if positioned properly) as well as maybe adding a few db of output. However if you don't have issues with room modes and you could go with just one sub, the sub 15 would definitely improve upon what you have now.
The Sub 10 is hilariously inadequate for a room of that size. Sell it and get a real sub. I wouldn't both with any of the other Paradigm subs, at least if you can't get a really really good discount on them. They are good subs, just way over-priced for the performance you get.
