Sorry I couldn't help myself. So how long until dave starts working on the next tower? Something that requires no sub whatsoever but still plays balanced music.

RAAL tweeter
Updated midrange cone
Updated 5.5" woofer
New 6.5" woofer
New 8" woofer
New fancy crossover that somehow magically makes it all work.

Come on dave make it happen. Take everything that makes the sierra tower good and add gut rumbling thunder when appropriate. I need this. Please.
