Who are some of elite sub woofers?

Thank you all for insight.
Budge I'm guessing $1500 but thought about only one?Millercarbon suggested 3-4? That would change budget considerably.

I’m gonna plug SVS simply because I own two SB-2000s (sealed version, 12 inch driver, 500 watts RMS, continuously adjustable for volume, phase and low pass filter) run in stereo. Not only do they sound wonderful, but they are well built, low profile and are priced for high value. Bass quality is quick and powerful with very clear, defined and textured sub-bass notes. I should add you could buy two for $1400.

Another +vote for REL.

Happy Listening!

+1 for JL. Fathom v2 only. Earlier versions had issues but those been worked out in v2. Costly but worth it especially when dual duty, HT and 2Ch, is desired. It is the best small powerful and audiophile sub available. Do some homework and auditioning.
