Subwoofer Suggestion

I got the DEBRA array (4x 10” passive subs powered by 2x 1000w amps in my 15x20 room. I’ve tried upgrading speakers and still no bass (Tannoy Turnberry). Turns out it’s because of the standing waves in the room. I tried changing speaker location and listening spot- a little improvement. Once I added the DEBRA, completely got rid of my bass problems and blends perfectly. Best money spent on my system so far. 

I've checked the Debra array sadly it's again out of my budget. Now I'm starting to think that I spent too much on amplifier and speaker😂

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.
