What are the best subwoofers you have heard for music. Speed, Musicality and integration

@jafant i had a sunfire true super jr that I loved.  It was such a great sub but it died on me.  It got replaced by two RELs.

@calvinj 

i started a REL thread in the speakers forum a few weeks ago.  In a few days I will have a T9x installed in a secondary system

Expensive, but the Bowers and Wilkins db series. Extremely musical and can easily  

Work with any speaker. 

I switched from  JL Audio Fathom F112’s to NSMT Sub Duos They retail for $4,495 each. They are very easy to integrate and give me the best bass I’ve ever had.  The next model down is called the Bass Foundation which are $2,500 each. I have not heard them but I hear they perform the same as their big brothers in a smaller room. The If you are interested I’d contact Mike from Audio Archon. I highly recommend the sub woofers and Mike. Just my experience for what it’s worth
