Featuring a hemp cone, 1” voice coil and lightweight 15 oz. ceramic magnet, the 4 ohm 620H offers 20 watts of warm, full, and clean tone that will make a small, thin amp sound bigger and fatter. “The 620H is the little brother to the 8” 820H we introduced last year.” said Anthony Lucas, Eminence tech support specialist. “The 620H sounds cleaner, warmer and fatter, with better definition than any stock 6.5” speaker you will find. A perfect upgrade to just about any small amp on the market."
