Morel Primo PSL 10.4 10 Inch Shallow Mount Car Audio Subwoofer

Morel Primo PSL 10.4 10 Inch Shallow Mount Car Audio Subwoofer

Precision-engineered 10-inch shallow mount subwoofer from Morel's Primo SL series, delivering high-fidelity bass in space-constrained vehicle installations with just 89mm mounting depth, a rigid polymer cone, and 300W RMS continuous power handling.

Product Overview

The Morel Primo PSL 10.4 is a 10-inch shallow mount subwoofer from the Primo SL series, designed for enthusiasts who demand clean, musical bass with deeper low-frequency extension in vehicles where mounting depth and enclosure volume remain a constraint. With a mounting depth of just 89mm, the PSL 10.4 enables large-driver bass performance in hatch floors, under-seat enclosures, and compact custom builds where a conventional 10-inch subwoofer would be impractical.

The PSL 10.4 employs a rigid polymer cone with an exceptional stiffness-to-mass ratio, ensuring fast transient response, low distortion, and natural musical bass integration from 10Hz to 500Hz. 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 at the PSL 10.4's 300W RMS continuous power handling.

Optimised for compact sealed and ported enclosures, the PSL 10.4 suits modern vehicle installations where space efficiency is essential but a step up in output and low-frequency extension over an 8-inch driver is desired. 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 an 8-inch configuration (PSL 8.4) for installations with tighter space constraints. Contact F.A.E. if you require guidance on which size best suits your enclosure and vehicle application.

Features & Benefits
