JL Audio Built In USA

Awesome bass and classic style

This M7 Series 12" marine subwoofer reflects JL Audio's commitment to awesome sound, cutting-edge styling, and quality engineering. JL Audio designed this high-performance subwoofer for free-air use or for larger enclosures, so you can choose the option that best suits your boat.

Handles up to 600 watts RMS

This rugged sub can really rock, with a massive magnet and heavy-duty componentry that can handle up to 600 watts RMS. It's tough, too, with a sealed waterproof front and the stylish, UV-resistant titanium-finish "sport" grille. Add it to your existing system, or use it in conjunction with JL Audio's marine speakers to create a powerful sound system that will really rock the waves.

The motor structure allows for extended cone movement, so your bass will be loud and low, yet precise and smooth. This versatile sub will work in sealed or ported enclosures, but it's optimized for free-air applications, so you can mount it directly into a bulkhead if there's no space for a box.

Built for life on the water

Built from the ground up for the marine environment, this rugged subwoofer sports a corrosion-resistant polymer basket that surrounds the internal structure for extra protection. The marine-grade synthetic fiber spider, injection-molded polypropylene cone, and synthetic rubber surround provide outstanding performance, while shrugging off the corrosive effects of sun, salt, and moisture. The UV-resistant grille will stay factory-fresh even after years of outdoor exposure. As an added bonus, you're protected by JL Audio's 2-year warranty.

12" 4-ohm marine subwoofer
gloss white Sport grille included
injection-molded mica-filled polypropylene woofer with synthetic rubber surround

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 surround is 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; the basket encapsulates the woofer's motor system to prevent corrosion.

Infinite-Baffle Operation: The M7-12IB 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, 3 ft³ is the minimum recommended volume.

Enclosure: If mounting in an enclosure, JL Audio recommends a 3 ft³ sealed or 5 ft³ ported enclosure.

4 questions already asked

Good day, will a pair work on a JL Audio M400/4?

robert Apr 29, 2023

1 answer

Greetings Robbie, and thank you for your question. The M400/4 amplifier by design is to run full range speakers. Two channels bridged can run a subwoofer, but one that requires less power than the M7. If you are planning on running two of the M7s in a free air space, you need the XDM 600/1, but if you will be building enclosures for these two subs, you then would need the XDM1000/1 amp.

What size hole is needed?

tyler Apr 09, 2023

1 answer

I would be happy to help, Tyler. This solid JL Audio M7 12" subwoofer needs a hole cutout of 12-1/16". These are some of my favorite marine subwoofers, true performers!

Hi Rod. I'm sorry we don't. We are also out of the white ones as well.

kenneth Nov 03, 2021 (Staff)

Will 1 of the JL audio M7 12 inch sub woofer marine speaker sound good or do I need 2?

martin May 31, 2024

1 answer

That would depend entirely on the size of the boat and how much bass you are really trying to get from it. We have advisors who can be reached by calling 1-800-324-9695 that can help go over your setup and recommend the best configuration for your goals.

We'd love to know what you think

Audition speakers before you buy

SpeakerCompare simulates the sound of home and car speakers through your headphones. It lets you compare sonic characteristics between speakers so that you can make a more informed shopping decision.

Why selecting your headphones is important

SpeakerCompare tailors your listening experience to the exact headphones you have, so that what you hear is comparable to auditioning speakers side-by-side in person. Knowing which model headphones you’re using lets us remove any sonic coloring from your experience.

Two different listening modes

In an actual listening room, you'd find that some speakers play louder than others when fed the same amount of power. In equal power mode, you'll hear these differences in loudness as they naturally occur between speakers.

In equal volume mode, we've made the loudness of each speaker about the same. This gives you a more direct comparison of subtle voicing differences between speakers.

Nothing beats listening to speakers in your space

SpeakerCompare gives you a sense of the sonic differences. But performance in the real world is affected by the acoustics of your car or home, your choice of amplification, and your source material. We still believe that the gold standard for auditioning speakers is hearing them in your own environment — that’s why we offer a 60-day money-back guarantee.

Our Listening Kit

To help you choose the right speakers, we recommend using Crutchfield’s SpeakerCompare Listening Kit. It includes a pair of studio-quality headphones, and a guide to getting the most out of your session, and a few other necessary items. We’ve carefully chosen the components of this kit to ensure a crystal-clear listening experience. It’s available for a nominal rental fee, and includes a $25 Crutchfield merchandise credit.
