Description

Massive Audio Summo64S

At Massive Audio they aim to make unique designs to solve different challenges in audio.  For example, they approached the 10” & 12” shallow mount subwoofer market with the very cool UFO series.  But what if you needed even more extreme space savings with a smaller sub, while still having great bass in your ride?  The Massive Audio SUMMO64S is an innovative approach to that solution.

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, they make up for it by increasing the outer diameter.  That way no motor strength is lost, yet mounting depth is improved.  They also moved the SUMMO64S to a solid pole motor design to increase motor strength even more by adding steel inside the motor.  Your first thought might be, wait, doesn’t that affect the cooling?  Sure it does, that is why they went with a new basket design that employs loads of side vents for air flow out of the motor to keep the voice coil nice and cool under intense bass notes.  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.

Now, you might notice there is a hex head screw in the back of the motor.  No, that is not to take the SUMMO64S apart.  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.

The SUMMO64S shares vital performance parts from the SUMMOXL line, such as the Kevlar Fiber enhanced non-pressed paper cone and OFC direct leads.  In addition, a 4-layer, high temperature voice coil, fiberglass woven dust cap, a high roll surround, and triple black poly cotton spiders with a mirror image layout.  All of the DNA from the SUMMOXL line, mixed with the innovative motor design, adds up to a very strong approach to a compact and shallow mount subwoofer that can keep up with the big boys.
