Sundown Audio U-Series 8" Subwoofer D2/D4

Description

    • 750W Watts RMS / 1500 Watts Peak
    • Dual 2 or 4 ohm voice coils
    • Optimized for small ported enclosures
    • Aluminum 2.25” voice coil former for superior heat dissipation
    • High-temperature copper voice coil
    • Double stitched surround
    • Heavy-duty cast basket
    • Spring-loaded terminals accept up to 8-gauge wire
    • Stitched-on heavy-duty tinsel leads
    • Solid pole with vent channels and aluminum shorting ring cap
    • Rear gap-venting
    • Top-Plate Cooling Channels

    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.
