I concur. REL is the best sub (for music) in the market.
JL Audio does a nic job for HT applications only.
A misplaced dogmatic statement.
I've heard JLs in a variety of music-only systems, including matched with panel speakers, and they can blend in seamlessly with no risetime lage or timbre-matching challenges. There are scads of pro reviews of the JL Fathoms and Gothams to corroborate this, even when used with solo classical guitar.
