Morel Primo PSL 8.4 8 Inch Shallow Mount Car Audio Subwoofer

Morel Primo PSL 8.4 8 Inch Shallow Mount Car Audio Subwoofer

Precision-engineered 8-inch shallow mount subwoofer from Morel's Primo SL series, delivering high-fidelity bass in space-constrained vehicle installations with just 80.1mm mounting depth, a rigid polymer cone, and 250W RMS continuous power handling.

Product Overview

The Morel Primo PSL 8.4 is an 8-inch shallow mount subwoofer from the Primo SL series, designed for enthusiasts who demand clean, musical bass in vehicles where mounting depth and enclosure volume are at a premium. With a mounting depth of just 80.1mm, the PSL 8.4 opens up installation possibilities in hatch floors, under-seat enclosures, and compact custom builds where a conventional subwoofer cannot be accommodated without compromise.

Unlike shallow mount subwoofers that sacrifice excursion or tonal accuracy for a reduced profile, the PSL 8.4 employs a rigid polymer cone with an exceptional stiffness-to-mass ratio, ensuring fast transient response, low distortion, and natural musical bass integration across its 15-500Hz frequency range. The heavy-gauge stamped steel Uniflow chassis minimises resonance while improving airflow around the motor structure, and the 51mm voice coil combined with a rear-vented motor ensures thermal stability and sustained clean output during extended listening sessions.

Optimised for compact sealed and ported enclosures, the PSL 8.4 is well suited for modern vehicles where space efficiency is critical without compromising sound quality. Push terminals simplify connection, and the single 4-ohm nominal impedance makes amplifier matching straightforward.

Morel products are assembled by hand and undergo seven quality tests at the company's in-house facility before leaving the factory, a standard of build and consistency the brand has maintained since 1975.

Note: The Primo SL series is also available in a 10-inch configuration (PSL 10.4). Contact F.A.E. if you require guidance on which size best suits your enclosure and vehicle application.
