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.

About the Morel PRIMO SL PSL84
From our tech experts at CEN
A 8 inch subwoofer, 4 ohm, handling 250w RMS.
Who it suits
Drivers building a system where the bass has to keep up with a good front stage rather than simply be loud.
Our tech experts advise
A subwoofer is only as good as its enclosure and the amplifier driving it: box volume and tuning decide what you actually hear, and impedance decides how it should be wired. We build enclosures to suit the vehicle at our Beeston workshop. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs.
