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.

Maximize Bass Reproduction and save on airspace via this innovative new design!

This new cast basket and sealed bottom plate design will replace traditional bottom venting by redirecting the cooling from the pole piece vent to the bottom of the customized basket. this allows the subwoofer to be installed where the depth is limited.

By bolting this machine screw through the back of the enclosure to the backplate of the subwoofer you will minimize 'box flexing' and reduce the airspace needed in the box itself!

Minimizing box flexing will increase efficiency by converting the wasted electrical power from the amplifier directly to the mechanical linear subwoofer cone's movement which will minimize distortion and add more efficient bass reproduction.

Normally you would need around an inch or more from the back of the subwoofer to the back of the box. On the back of the SUMMO64S you will find a removable machined screw. Simply remove the screw, load the subwoofer in the enclosure so that the back of the box is flush with the back of the subwoofer, then replace the screw through the back of the enclosure to the baffle of the subwoofer.

This design will allow a unique advantage of bracing the front baffle, the subwoofer and the back baffle together as one, which will make the subwoofer and the enclosure as one plane.

This will not only make for a smaller box but more importantly add more bass! This is due to the energy not being spent on box flexing and in turn producing more low frequency output!

Now that’s audio innovation!

Let there be no doubt that with Massive Audio you will be the “King of the Ring.”
