Going through my storage I found a 15" electro voice speaker I used in the 80s. I think the speaker alone weighs more than my bergie and accugroove cabs. Does an older 15 offer any merit? Sub-woofer? Old-school vibe? Should I get a 1x15 cabinet for it? I'm not interested 2 way or 3 way cabinets since my current rigs cover that beautifully. Suggestions?
