In the ancient Japanese sport of "SUMO" the rules are simple. When some guy says (something that doesn't sound like) "GO" push the other guy out of a big circle! Will when Massive Audio created the "SUMMO" line of subwoofers for 2014 they blew all the rules and the competition out of the ring! The SUMMO subs play so low with such a deep center of force that the competition will be ejected from the ring! There are 5 new SUMMO subwoofer models for 2014. Subwoofers start with the "BIG MO" Model 154 followed by the 124 and then the 104. All three rated at 3000 watts! Next is the 600 watt 84. The comes the little bump down the crowd pleasing model 64 300 watt subwoofer. Massive Audio is "King Of The Ring".
