Primo SL Subwoofers

The Morel PRIMO SL is precision-engineered to deliver true high-fidelity bass in installations where mounting depth and enclosure volume are severely limited. Unlike conventional shallow-mount subwoofers that sacrifice excursion or tonal accuracy, PRIMO SL employs a rigid carbon-weave cone with an exceptional stiffness-to-mass ratio, ensuring fast transient response, low distortion, and natural musical integration.

Available in 8″ and 10″ configurations, PRIMO SL is optimized for compact sealed and ported enclosures, making it ideal for modern vehicles where space efficiency is critical without compromising sound quality.

To sustain clean output in tight spaces, PRIMO SL features a heavy-gauge stamped steel Uniflow™ chassis that minimizes resonance while improving airflow around the motor structure. A large 2-inch voice coil and rear-vented motor enhance thermal stability and cooling during extended listening sessions. With ultra-slim mounting depths of just 3.125″ (80.1 mm) for the 8″ and 3.5″ (89 mm) for the 10″, PRIMO SL delivers powerful, controlled bass performance in locations where traditional subwoofers simply won’t fit.
