I have a Boogie Mark 1 that I purchased in 1993. It has an Electro-Voice EVM-12L speaker in it. When I disconnected the speaker and ran the amp through my 2x12 cabinet with JBL E-120's, it sounded identical. EVM's are great speakers, and may offer a good alternative to the E-120's now that JBL is no longer making recone kits.
I have two EV's. Rated at 300 watts. Very clean.
