Ascendant Audio SMD

Ascendant Audio

The SMD Signature Series of subwoofers comes from working with Steve Meade and his monster installs for close to a decade.  Seeing the progression of subwoofer and amplifier technology we have put pen to paper and designed several new technologies to help push things to the next level.  Starting with the obvious, the motor, it is a Super Gauss dual flux path motor with incredible motor strength not before possible from a ferrite motor structure.  Integrating our 4" EMB coil topology to the system provides electro-mechanical braking to linearize flux.  Having all of this motor force and linearity are no good if you can't handle power thermally. Every SMD produced spends a significant amount of time on one of our 4 axis CNCs machining the Dyna cool system into the internal parts of the motor structure.  Utilizing cooling channels and specific paths in both the gap plates and pole piece we can extend the thermal capacity of the sub out to 3500W RMS in its normal range of musical operation.  Keeping it mechanically under control is a 7 spider Tri-point suspension system with integrated lead wires capable of handling tremendous current.

All of these technologies culminate in the pinnacle of daily driving subwoofer performance.  Working in ported enclosures much smaller than the average sub, you can get displacement never before possible in tiny spaces, often allowing you to step up to the next size driver for even more output capability.
