I played a gig on Monday at the Green Mill with the Judy Roberts Quartet and used my EA Doubler and one of Mike Arnopol's new Big E Cabs. This one has four 5" speakers and 6 rear firing tweeters! The cab weighs about 30 lbs., is ply construction and is a pretty small guy, but I don't have the measurements. In a nutshell, the cabinet sounds great. The front end thump of the note is really accentuated creating a very powerful sound and sensation. The other cool thing about this cab is that notes in thumb position jump out in a way I haven't heard before. I'm used to the higher notes of the bass weakening, and they don't with this cab. If anything, they seem to gain energy. Consequently, you don't need to play hard to have definition and be heard. The sound is also very natural without the electronic character I'm used to in DB amplification. I've played many gigs in this room with many different amps/speakers and this is one of the best experiences I've had. The Crazy88 being another. I think the Big E is in a class by itself, though. I will use it again tonight at the Jazz Showcase and report back. For technical details, you'll have to ask Mike.
