Musical subwoofer under $2000

You want punch in the gut tight bass? 
or blend just a little something down low?

Thanks for the feedback on looking at the SVS sb-2000 pro and going for two. As for musical I just meant I wasn’t looking for home theatre sound but just a sub for use with music, so not boomy or obvious apart from adding low end that isn’t fully there with the SF. I’ll definitely look at the SVS.

I use a stereo pair of Gallo Acoustic TR3-D subs, have for years.
Right in your price range, too.

For my setup to be of correct frequency : driver surface area balance, I should have 3 subs per channel (long tall story, literally), but one sub per channel is enough for me.

I haven’t heard a more worthy sub for music in its price range.*

I can anecdotally attest that lifted 45cm clear of the floor, speed and clarity even without DSP has visitors taken aback with bass from my setup. Most of them own or have listened to setups many times the value of mine (admittedly, mine’s not inexpensive).

My only disclosure is that my room is large, but solid concrete, all sides including ceiling; room gain is on the sub’s “side” in my use case. I can’t vouch for drywall applications, but perhaps others can.

Easy. Get two 12" Dayton Sub kits from Parts Express with Class D plate amps and a MiniDSP crossover. The kits are easy to build. You can paint them or cover them in equipment carpet.
