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?

One of the suggestions is build your own subs. Your own homemade DEBRA/swarm system.  Here is the amp used:

And a cheaper alternative:

The setup instructions are on the "debra" website. Just need to build four small  passive subwoofers. Build from scratch ( or pay a local carpenter/cabinet maker) with plans or buy a kit for 8" or 10" subs.

Ow I get it now, lol my dad would never let me do those though asian parents HAHAHAHAH
@kulo      Just so you know, RSL does not have dealers and they do ship all over the world.  You could do three subs for $1200.  Heck, you might be happy with two!  They really are a great value.
When I brought the kanta 3 home I loved the mids and highs but the bass was a mess, +10db at 100hz and -20 at 80 hz with a little recovery around 60 hz b4 falling off the chart. My room. Moving them to the long wall and playing with boundary placement did smooth them out a lot, but they never did offer much below 70 hz in my room. I would try a single sub between the speakers first and if that don't work then buy the second. A flat measuring speaker isn't necessarily desirable and the Kanta only needs help with the bottom 2 octaves.
