Subwoofer Suggestion

I just auditioned a pair of RSL Speedwoofers.  This is a compact 10 inch sub that has to be the best value sub for the money I have heard.  It can reach down solidly to 25hz, is compact, all for a bagain price of $400.  Shipping and return shipping included!  So get 4 of these subs and you ought to have effortless, smooth bass well suited for a 50/50 split of music and HT.  What have you got to lose?  Highly doubt you would return them

I have 4 systems - main (living room), office, bedroom, computer room. My living room is pretty big and opens into my kitchen. 4 subs there. All the others have a single sealed sub and sound great. 

If your goal is gut punching bass, you need big powerful subs. That's not what I'm trying to achieve when listening to music (although I have the gear to do that).  If there's bass content in the music, I hear it much like it would sound live. And when there's some really deep bass, it is visceral.

The OP has a big room. Multiple subs are the easy button for well integrated bass if there's room and budget. 

Thanks for your opinion guys, the dealer recommended the Focal sub 1000 F although I haven't heard it, I'm pretty sure that it won't be
enough for my room and I think I can do better with PSA or svs subs for that amoutn of money.

Elliot sadly it doesn't reach deep enough
compared to the Revel studio2 that I auditioned. I've just recently made the purchase, this is my first hi fi system. To be honest, I'm still trying to decipher your response since I am relatively new to speakers. By the way upgrading later on isn't an option since my dad just wants a one and done system.
