Morel Primo SL PSL84 8 Inch 4 Ohm Shallow Mount Subwoofer 250w RMS
MOREL PRIMO SL PSL84 8 INCH SINGLE 4 OHM SUBWOOFER 250W RMS
The Morel PRIMO SL subwoofers are precision-engineered to deliver true high-fidelity bass where mounting depth and enclosure volume are extremely limited. Unlike conventional shallow subwoofers that compromise performance, the PRIMO SL was developed to outperform conventional subwoofers, using rigid carbon-weave cones with an exceptional stiffness-to-mass ratio for fast transient response, low distortion, high output, and natural musical integration.
Available in 8” and 10” sizes, the PRIMO SL are optimized to perform with exceptional accuracy in compact sealed and vented enclosures alike, making them ideal for modern vehicles where space efficiency is critical. Heavy-gauge stamped steel Uniflow™ chassis, large 2-inch voice coils, and rear-vented motors ensure clean, controlled output and thermal stability. With ultra-slim mounting depths of just 3.125” and 3.5”, PRIMO SL delivers powerful bass where traditional subwoofers won’t fit.
