I have not had a chance to hear or play with one of the Big E cabinets so I can't comment on them. I can comment on the other two speakers, which are the primary speakers I use for double bass gigs. I have one of Mike's composite Crazy 8 speakers and find it fantastic for any DB gig with a smaller group. I also like it for EB jazz gigs, although it certainly can't get loud enough on its own for doubling/dance gigs. I drive the speakers with either an AI Series III Focus or a very small and light AI Clarus SL. This Clarus has no HiPass filter so I put an FDeck into the input.
If I need really loud volume, like for a doubling gig or pure EB gig for a dance or show without PA Support, I use a Barefaced Midget speaker, and have two of Alex Claber's newest speakers a Super Midget and a Big Baby 2--on order. They sound good for DB as well although they are fantastic for EB.
If it is a loud DB gig, like a big band with little or no PA support, or a theatre gig, then I take the Ten2Ex with the AI Focus as my rig of choice. I play regularly with a touring Rat Pack show with an 8-piece band that gets loud. Since we're always in different theatres, the quality of the PA support varies a bunch, and I use the Focus/Ten2Ex combination as my stage monitor. With the volume of the band, I need some serious volume and this combination provides that perfectly even though my amp is generally right behind me on a small stage riser. The trick is to turn down the bass a bit, make use of the HiPass filter to take out the really low mud, tilt up the speaker, scale back the tweeter to reduce any harshness, and use the switch on the back to direct more of the sound out the front speaker. I do leave some in the bottom speaker though since that sound tends to be heard by the rest of the musicians on the stage. I've been able to get a very tight, punchy sound this way that helps the music swing and also delivers clear tonality.
I appreciate that YMMV. Oh, and just to complete the description of what is in my signal chain, I play a LaScala Hybrid with a single Rev Solo II pickup.
