Product Research

Features

Overview: The JL Audio FS108-W5-SG-WH is an enclosed subwoofer system designed for installation in a boat. It is equipped with an M8W5-SG-TB 8" subwoofer driver installed in a sturdy, all-fiberglass enclosure with a beautiful, gloss-white gel-coat finish. The enclosure is precisely tuned to provide the best bass output for an open-air boat installation.

Note: The enclosure is not drilled for speaker wire, and has no external terminals. It is up to the installer to determine the best location on the enclosure to drill an exit hole for the speaker wire, based on the location chosen for mounting the subwoofer.

Marine Tested: JL Audio's marine subwoofers go through ultraviolet testing chambers (to simulate years of sun exposure) and salt fog chambers (to simulate years of exposure to salt-water environments and are built to withstand the rigors of marine use.

Woofer: The M8W5-SG-TB subwoofer features an injection-molded, mica-filled polypropylene cone woofer with a synthetic rubber surround specifically formulated for marine use. The woofer uses a vented motor design with a marine-grade stainless steel rear diffuser plate and a marine-grade synthetic fiber spider with a progressive roll design. It has marine-grade brass connection terminals (male quick slides, .250"/.1875"). Marine-grade, stainless-steel mounting screws and washers are included (pre-installed on sub).

DMA (Dynamic Motor Analysis): JL Audio's proprietary Dynamic Motor Analysis (DMA) technology results in ultra-linear motor force over a long range of excursion and a wide range of power inputs to reduce distortion and improve sound quality.

Polymer Basket And Grille: The Centrex, UV-resistant polymer basket and grille are corrosion and UV-resistant which help protect the woofer and encapsulates the motor assembly to prevent corrosion. The white-colored Sport-style grille is installed on the woofer.

Installation Notes: The enclosure should be securely mounted to the location you have chosen. It is recommended that at least 2 mounting bolts are used to secure the enclosure--three or more for extra strength and stability. This involves drilling holes in the base and the mounting surface for the mounting hardware. Stainless steel hardware (hex head bolts, fender washers, lock washers, and hex nuts) should be used to resist corrosion. An additional hole needs to be drilled in the enclosure for entry of the speaker wire. Silicone caulk should be used to seal the enclosure and protect the wire from abrasion.
