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?

@kulo The REL T/9i retails for $1299 USD. But in my experience you can buy them (I bought two) for a discount from a dealer in the US. I don’t know where you are located. 
I'll give this a try thank you.
As stated above, consider rolling off the mains.

king baracyda I'm located in Philippines, everything here is so expensive compared to US.
@Kulo:

El Pipe-O is a DIY sub. Quite a large variety of woofers can be used as drivers. I’m sure you could find a suitable pair locally.
