I found these cabaret cabinets for sale that were not so local. The upper drivers were already wasted or missing. The guy was very cool and said he would hang onto them for me. I hate working with wood and I've been looking for some e145 drivers, so it was a perfect situation. I've had all of the other parts on the shelf for many years. The horns are a Yuichi a290 design and the drivers are 2445 with 2452-sl diaphragms. The entire horn assembly feels like 80lbs This was all cobbled together last night while repairing stuff along the way. Tonight, the sl phragms/foam pads were installled and more work was done in the driverack. Turns out that they like a lower order Butterworth filter. For no measurements or eq, the system is quite listenable as is. You would need put your head in the horn to pick up any noise. I tried to work in some 2405 drivers, but I've not found a decent amplifier yet. I'm looking for something with low dc output, low noise, and a protection relay. There are two 6215 amps that are dead on the bench with several hours into repairs. There is another D45 that has no relay and puts out dc on shutdown.
