It's been a long haul to get the BigE cabs done for the local theater. I thought I was done in Dec, but then realized there were 10 surround cabs. I wasn't willing to do a partial system, so we started in. Had to come up with a design first, then prototype and build.
I now have 14 of the crazy things sitting around the shop. 2x5. The surrounds are pretty much wired. 4 of them are going to be monitors for a couple of friends who record. They require much higher fidelity than the surrounds. Still playing with the correct tweeter for them. I've tried a couple of different woofers with really good results. I had some closeout sonys that I started with. Really good, great mids, good bass. Then I dropped in some very low fs long xmax Peerless drivers. The bass is stunning. You'd swear I have a subwoofer running with them. But it did cost some mid quality. Playing with tweeters and moving the crossover point around to fix it. I like running the mains full range, but I'm pretty sure with these I need to install a low pass to roll them off and let the tweets take over about 2.5-3k. I have some Faital 5's coming to give a go also. They're what Mike Arnopol uses in his 4x5 bass cab, and it's his favorite cab in the BigE line.
In other news I just keep cranking out the fEARful flat packs. Dave has really hit a home run with these. Traditional designs, optimized for the new generation of drivers available. I'd really like to do a FEARLESS, but nobody's ordered one. (Hint). The 2x15 and the F112 are blowing up. The other builders are doing lots of them. BNA has a booth at Namm this year with fEARfuls and FEARLESS cabs in it. You should stop by if you're going. Mark's a great guy.
