Coax. No tweet.
Actually, coax tweeter. The Coax tweeter is under the dust cap of the driver, similar to the Bag End 'x' models. I went this route so that I could get the smallest box possible, since the additional of a stand-alone tweeter would result in the box being quite a bit larger to make room in the baffle board for the stand-alone tweeter. I also went the rear porting for the same reason.
This cab was kind of an experiment, and Don and I had fun with it. My design goal was the highest quality, full range 112 that I could get in the smallest possible dimensions. Don did a GREAT job with this one.
