Morel Primo Slimline 10" (250mm) Subwoofer 300W at 4 Ohm
Product Description
The Morel Primo Slimline 10" 300W Subwoofer (MOR PRIMO SL 104) is the larger format in Morel's new 2026 PRIMO SL shallow-mount subwoofer series — delivering greater bass extension, higher dynamic headroom and more physical low-frequency impact than the 8" model from the same ultra-slim mounting depth of just 3.5" (89mm). A brand-new Performance-tier engineering achievement, the PRIMO SL 104 opens up genuine 10-inch bass performance in vehicles and enclosure configurations where a conventional 10-inch subwoofer's mounting depth requirements would make installation impossible.
The PRIMO SL 104 shares the carbon-weave composite cone, Uniflow™ heavy-gauge stamped steel chassis, rear-vented 2" voice coil motor and compact enclosure optimisation of the 8" sibling — all scaled to take advantage of the 10-inch cone area's greater displacement capability. The larger cone moves more air per unit of excursion than the 8", extending usable bass response deeper and producing greater dynamic impact at equivalent drive levels. For installations where the vehicle's available enclosure depth is limited to shallow configurations but where the bass should be heard as well as felt, the PRIMO SL 104 is the product that makes this possible at the Performance tier. At 3.5" (89mm) of mounting depth, it opens installation scenarios that would simply be impossible with any conventional 10-inch subwoofer. Specifications: 4 Ohm, 300W RMS, 3.5" (89mm) mounting depth.
