USSpeaker has them listed for $749, I may snag a pair as they seem to be an upgrade over the RCF LF21N451 I still run in my dual 21s.
After my B&C/18 Sound/RCF showdown that resulted in the N451 years ago, great to see another contender. Also great to see Eminence respectably jumping into the ULF fray.
Oh, hey guys :)
