Massive Audio SUMMO64S

SUMMO64S

What makes the SUMMO64S special, yet unique in design you ask? Well it's all in that new motor and new basket. The SUMMO64S is taking the approach of reducing the height of the motor by reducing the height of the magnets. But don’t worry, Massive Audio make up for it by increasing the outer diameter. That way no motor strength is lost, yet mounting depth is improved. A benefit of the solid pole with no rear motor vent means you can go super shallow with the SUMMO64S as it does not need airspace behind the motor to stay cool.

That hex head screw is to take the efficiency of the SUMMO64S up another notch. When a subwoofer is playing deep notes, often baffles can flex and that causes output loss if there is enclosure flexing. You want all of the output coming from the cone and port, not lost or wasted in the box flexing. All of this means, you can physically mount the SUMMO64S not only to the front baffle of the enclosure, but also to the rear of the enclosure. You can do this by running that hex head screw through the back of the enclosure, into the back of the subwoofer motor. This will mechanically lock everything into place much more rigidly without it. You see, special and unique.
