Active Subwoofer Recommendations

Paradigm Defiance V10 Retail $550 - Has Anthem Room Correction and full App Control from your phone - wireless capable although doing that is a last resort, better to run a wire - check it out at Paradigm.com and look up videos on YouTube about the Defiance Subs.

3rd the Rythmik L12.  They stand out in sound quality at this price.  The only other subs I would consider at the price point are HSU.  

Before you can enjoy it all, you have to integrate the subwoofer with rest of your system, and how you connect a subwoofer to the rest of your home theater setup depends on whether it is Passive or Powered. That’s how we do in our management setup. حسين البداد

I use two subs — left and right — powered 8”   Velodynes. The bass is utterly awesome. It is almost as if the room shakes. 😁

+4 on the Rhythmik L12.  Down 3dB at 18Hz for about 500 bucks -- that's just nuts.
