Research for subwoofer

Another vote for SVS!

2 Rythmic's and you'll be happy but 4 would be better.

I read through the responses and didn’t see a budget mentioned.  Probably just missed it. Also no mention of Legacy Audio. I run a 5.2 home theater system (see virtual system) with all Legacy speakers. The two subs are the Foundation model. I didn’t have them initially. I thought the big 15” woofers in the mains were enough. Ran it that way for many years. This year I stepped up and added the two Foundation subs. What an improvement. Night and day. Anyway, my two cents. 

My suggestion is that you might want to further define/refine what you are trying to accomplish.  There is the bass you hear, the bass you feel and the bass that shakes the room.

Getting "more" bass is not hard, but getting the kind of bass you want where the subwoofer/s play nicely with you room and you speakers can be more challenging.

I’ve owned subwoofers from Power Sound Audio, REL and SVS.  They are all excellent in their own way and they can all be made to give you good bass.  I achieved the most sense of bass power from the PSA, the absolute easiest integration from the REL and ever so slightly the best tone from the SVS.

My recommendation is pick one of the better brands with a good "try at home" and return policy and you might luck out and find the perfect sub with your first try.

snapsc - That is what I have chosen to do.   Budget was under 2k

Trying REL first.   I am looking for more Bass that I hear and a fuller soundstage
