The sound: the old jbl is very louder in this box. midrange is clear and evident. The piezos add the sparkle on the top ( could be more clear to my taste). the band can hear finally all the notes i play

I could take more punch from the woofer when slap and pop. probably due to the JBL

overall a very good cab FAR better than all the other 15 inches that i ever heard and try.
THANK YOU BILL for all these fantastics designs! I AM ADDICT!!

Next build: 2 omni 10 ( 4 betas on hand)
and DR 250 /280 or both
