Product Research

Features

Marine Tested: JL Audio's marine speakers are tested in ultraviolet chambers to simulate years of sun exposure, and salt fog chambers to simulate years of exposure to salt-water environments.

Materials: The woofer cone is mica-filled injection-molded polypropylene (IMPP) with UV inhibitors. The surrounds are synthetic rubber and the woofer uses a marine-grade synthetic fiber spider with a progressive roll design. The basket and grille are UV-resistant polymer; they encapsulate the woofer's motor system to prevent corrosion.

Infinite-Baffle Operation: The M6-8IB is optimized for infinite baffle operation so that it can be installed in a variety of locations, without the need for a dedicated enclosure. If an enclosure is used, 1.5 ft³ is the minimum recommended volume.

Enclosure: If mounting in an enclosure, JL Audio recommends a 2 ft³ sealed (1.5 ft³ minimum) or 1.5 ft³ ported enclosure.

For information on selecting the best amp for your subs I would recommend reaching out to an advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system.

Q
Also can u remove the grille? Or cld y'all get the grille in chrome??
dale  Feb 22, 2023

A
JL does not offer a chrome grille options sadly, Dale. That would be slick! With the sport model, you can remove the 6-star insert (trim ring and center ring remains). The JL audio M6-8IB-S-GmTi-i-4 with LED in the below link would be the closest to chrome we have, check it out! https://www.crutchfield.com/p_13693620/JL-Audio-M6-8IB-S-GmTi-i-4-Gunmetal-Sport-Grille-and-Titanium-Grille-Insert.html

Q
Do ths speaker hv led lighting around the speaker?
dale  Feb 22, 2023
1 answer
A
This model JL subwoofer does not, Dale. If you would like the LED lighting, go with the M6-8IB-S-GwGw-4 in the below link. This has the unique Transflective color cone, a must have for your LED setup! https://www.crutchfield.com/p_13693618/JL-Audio-M6-8IB-S-GwGw-i-4-Gloss-White-Sport-Grille.html
