Just finishing up on a pair of Cabaret-like 3 ways. I’ve had my eye on the 4628's for a while and decided to build a pair updated just a bit.
The overall size, baffle layout and tuning are the same as the original but from there I made a few changes. One change was to mirror image the pair and angle the side walls back a little in a trapezoid fashion. I also set up the grills to wrap around the front a little, to reduce the side reflections if I decided to listen to them without the grills. The handles are recessed into the cabinets.
Like the originals the cabinet material is birch plywood, hoping to make them a little lighter and tougher for lugging around. With the E145s they are still a back breaker no matter what you do.
I already had the E145s and 2404s. The midranges are the equivalent but somewhat higher power 2119H rather than the 2118H.
I started out with a home built version of the stock crossover. This sounded just ok in full-range mode but the speakers really came alive when bi-amped. Not sure I wanted to bi-amp all the time, I swapped in a charged coupled 800hz crossover from a different project. The other crossover is a lot more complex, but doesn’t run the E145 full-range all the time. This sounded so much better, I decided to rebuild using this version. I kept in the bi-amp switch, which leaves the mid-tweeter section as is, and releases the E145 to run flat out.
Anyway here are a few pictures.
