Subwoofer Suggestion


Hi guys I need your suggestion regarding subwoofers. My system is composed of Focal Kanta 3, Kanta center, 706BK it would be used 50/50 for music and HT. My room size would be 13m by 4m by 3(Length,width,height). Would it be better to go for dual pb1000/sb1000 or single sb3000 or single pb2000 or single PSA S1500?

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.
I just fear that maybe the sb1000 wouldn't go deep enough, and for the pb1000 not to go tight enough. 
Two of the sealed SVS-SB 1000 should do the trick!  

SVS or PSA over Focal or Klipsch. The 1000 series SVS subs are entry level and under-sized for that room. If the desired outcome is to add a little more bass, they'll do that, but if you're expecting a major improvement, you may be disappointed. Only one way to find out. Can you return them?
