In the ancient Japanese sport of SUMO the rules are simple. When the Gyoji waves his fan; push the other guy out of a big circle. Massive Audio created the “SUMMO” line of subwoofers with the same goal in mind. Summo Series subwoofers play so low and with such a deep center of force that the competition cannot help but to bow out gracefully.

Models include the Summo 15”, 12” and 10” all rated at 3000 watts. Then there is the 600 watt 8” right on down to the crowd pleasing 300 watt 6” subwoofer. Let there be no doubt that with Massive Audio you will be the “King of the Ring.”
