Vibe Audio Slick 12 D2 (SLICK12D2-V3)
12″ subwoofer · dual 2 Ω · 500 W RMS
The Vibe Audio Slick 12 D2 (SLICK12D2-V3) is a 12″ subwoofer. With Qts 0.57 and EBP 46 it suits a sealed box: tight bass in a small enclosure; a ported box would need a lot of volume. Modest excursion (Xmax 0.43″) — for clean sound at moderate levels, not for SPL competitions.
