Description

UXL-18 – The Next Level

We are confident the UXL-18 will meet your design criteria for the very bottom octaves.  Regardless of room size, it will deliver low distortion, intricate yet subtle bass tones for even the most devoted music listener.  For home theater, expect the UXL-18 to provide you with sub-sonic output into the single digits with the right setup.  Use a single UXL-18 in a sealed, Bass Reflex/EBS enclosure, or multiple units in an Infinite Baffle configuration.  Whichever method you decide to use, you will achieve bass so low you will literally be able to count the sound waves as they pass you!

 

Highlights

The PS voice coil made exclusively by Mach 5, combines the very best technologies available.  It starts with a special non-metallic former, used because it does not generate eddy currents in the magnetic gap like metallic formers do.  This in turn reduces distortion significantly.  Heavy coated aluminum wire is CNC-spun using glues that have temperature ratings exceeding the magnet wire coating itself.  The adhesive is then heat bonded to ensure long lasting operation – a very time consuming and expensive process.

From our machine shop comes a CNC-turned magnet structure using quality North American steel parts, high energy ferrite magnets and strong adhesives.  Aluminum demodulating rings are applied to minimize distortion and a non-ferrous shield is placed within the motor to cut down on stray flux.  Like the PS voice coil, these modifications are something you may never see, but the sonic improvements will be nothing short of spectacular.

When dealing with the stress of very high excursions you need something that will maintain conformity.  We chose a dual layer craft pulp/carbon fiber diaphragm to achieve this goal as it provides both excellent damping effects and very high shear strength.  And let’s face it, the carbon fiber is pretty sexy too!
