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.

Thanks for your suggestion corelli, sadly, there aren't any RSL dealers here in Philippines. Svs, rel, and PSA are the only ones available to me. Also, my maximum budget that I am allowed to spend is around 77k php which is around 1500usd. Also svs subs are like almost double the srp here compared to the US, so I can't really go 4 subs unless I go for klipsch.
