Made another revision to the open baffle. I replaced the LS-12's with a pair of LS-8's, using a round adaptor board. Just a bit more refined sound. I really get into the OB sound, so big and open. The high Q EV drivers are a natural for OB's, and can be found well under $100 a pair at places like epay. They do require use of a sub and tweeter above 10 kHz.I'm using home-made wooden phase plugs on the LS-8's. Smoothes things out nicely.
