I had an Altec 417-8H in a Boog a while back and although I loved the clean sound of it the Metal Dome drove me insane when using lead distortion sounds. Same thing with the JBL E-120, outrageous for clean and Jazz tones but no go on Lead overdrive. I knew some guys at a sound Co. who were taking the metal dome off and replaceing it with a standard paper dome and presto a super good sounding speaker. But after discovering the EVM 12-L there's been no looking back for a great sounding speaker that would cover any style and remain true to what ever type amp or sound you pump into it!
