Description


The U-8 can be thought of as an SA-8 v3 on performance boosters. Everything there is to love about the SA-8 v3 just with more power handling, more x-max, and more output potential.
The specially designed motor is mated to a custom tooled and patented (US Patent D691595) frame which allows for a larger spider and superior clearances to nearly any other 8" woofer on the market today. The U-8 features a full 18mm of one-way linear excursion and mechanical capacity in excess of double the linear limits (around 2.5” peak-to-peak) to ensure that mechanical failures are nearly impossible. As with the SA-8 v.3 it features a surround that mimics the geometry of our large Mega-Roll v.2 surrounds for incredible linearity.
