Our take on the JL Audio MX10IB3-CG-WH

by Ken Nail
JL Audio

Great bass on your boat

The MX10IB3-CG-WH 10" marine subwoofer reflects JL Audio's commitment to top-quality engineering and sound quality. Its sparkling white finish and "Classic Grille" design make it a perfect match for many boat interiors.

Built for life on the water

Built from the ground up for the marine environment, the MX10IB3-CG-WH sports a corrosion-resistant Centrex® polymer basket that surrounds the sub's internal structure for extra protection. The marine-grade synthetic fiber spider, injection-molded polypropylene cone, and synthetic rubber surround provide top performance, while shrugging off the corrosive effects of sun, salt, and moisture. The UV-resistant polymer basket encases and protects the entire structure, plus UV protection ensures that the grilles will stay white, looking factory-fresh even after years of sun exposure.

Designed for a variety of enclosures

The subwoofer's motor structure allows extended cone movement, so you'll hear bass that's loud and low, yet precise and smooth. The versatile MX10IB3-CG-WH works in sealed enclosures, but it also works well in free-air applications, so you can mount it directly into a bulkhead if there's no space for a box.

Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.


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 subwoofer features an injection-molded, mica-filled polypropylene cone woofer with a synthetic rubber surround specifically formulated for marine use.

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.

Infinite-Baffle Operation: The M10IB3 is optimized for infinite-baffle operation so that it can be installed in a variety of locations, without the need for a dedicated enclosure.

Polymer Basket And Grille: The polymer basket and grille are corrosion and UV-resistant, and the basket encapsulates the motor assembly to prevent corrosion.

Connections: The speaker terminals are 0.25" wide gold-plated, marine-grade brass, male quick slide connections.

Mounting Hardware: Marine-grade stainless-steel mounting screws and washers are included.

Box Type: If mounting in an enclosure, JL Audio recommends a 2.0 ft³ sealed box. The M10IB3 should not be mounted in a ported enclosure.

Grille: The woofer is shipped with the grille attached (using three screws). The grille can be removed, but the woofer can be installed without removing the grille. If the woofer is mounted without the grille, several measurements are different:

  • Mounting Height: changes from 1.469" to 0.791"
  • Flange Height: changes from 1.065" to 0.5"
  • Frame Diameter: changes from 10.734" to 10.382"

Crutchfield Customer Review (What's this?)
Was hesitant to go with the IB3 instead of the IB5 but the JL700/5 amp I am running puts out 180 at 4ohms> not enough to really push the IB5 so I went with this one. Have to say I am very pleased. I got alot more punch than I was expecting. This is very nice sub and definetly add some much needed bass to my system.

Mounted topside in a bulkhead wall. Quality appears excellent - would be nice to have the opportunity for a review in 12mo. But for now, very happy. Driving with a JBLM200/2 amp mounted inside main cabin.
