Based around a 12" OSWG from Poland married to a BMS 4550 compression driver, this design also uses a 12" JBL 2206H mid.
Plans as follows:
A seperate cabinet also houses a JBL W15GTI 15" subwoofer. Yes, a car audio sub, with JBL's patented Dual Differential Drive system. I chose this driver as it will play relatlively low, without requiring a huge enclosure volume like some of JBL's counterparts, while still being ~92db efficient.
Cabinets are 50mm thick MDF, with an internal 25mm brace and all drivers rear mounted as to see no screws. This meant that the backs had to be removable which presented a few problems in itself, of which these are documented later on.
Edges are also feature a 25mm roundover (would have liked bigger but finding a router bit was proving difficult).
My next task was finding some (un)lucky sucker to do the hard work for me
He conveniently had access to a CNC, which made life much easier!
Wow, lots of wood! I think we used about 4 or 5 sheets of 2400 x 1800 x 25mm MDF.
Getting it back to his place sure was fun!
