Serious bass for boaters

On land or sea, a quality subwoofer is a must if you're serious about sound. Rockford Fosgate designed their PM210S4 marine subwoofer to bring booming bass to your boat, with plenty of power and rugged True Marine Grade components.

Made for life on the water

This 10" sub features a rugged, removable stainless steel sport grille that looks great and stands up to blistering sunlight and damaging moisture. Underneath the UV stable Centrex® injection molded shell and durable Thermo-Plastic Elastomer (TPE) surround, you'll find a polypropylene cone that's treated with UV inhibitors, plus a moisture- and tear-resistant Aramid fiber spider. This sub's suspension is designed to stand up to the pounding of big wakes and choppy water, so it'll never miss a beat at high speed — and neither will you.

A versatile performer

Powerful enough for bass-heavy music and versatile enough to work in sealed, vented, or infinite baffle installations, the PM210S4 is a great choice for anyone who's building a serious marine stereo system.

This sub packs a punch

I've been running a pair of Fosgate 282 marine speakers with a Pioneer 8604 amp. I thought that sounded really good when I installed that a few years ago. Decided to add a sub this year. This sub is everything Rockford claims it to be. Crisp and clear punchy base. Just make sure you find a BEEFY wall on your boat to install. This thing packs a punch. (N0 sub Box needed) The last thing you want is everything vibrating .

Pros: sounds great Easy to install

Cons: NONE

Product Research

Features

Marine Tested: Rockford Fosgate's PM210S4 marine subwoofer is subjected to ASTM B117 and ASTM D4329 test standards to ensure it can withstand the corrosive effects of salt/fog, as well as sunlight, moisture, and heat.

Woofer: The subwoofer features an injection-molded, mineral filled polypropylene cone with UV inhibitors. The TPE (Thermo-Plastic Elastomer) surround is also UV and salt/fog resistant.

Klippel Verified: The Klippel distortion analyzer, a device that uses a laser and sophisticated software to do large-scale analysis of drivers in motion, lets Rockford Fosgate optimize the sub's motor structure, voice coil alignment, and suspension to yield the best possible performance.

Centrex Basket: The basket and other plastic parts are made of UV stable Centrex injection molded plastic.

Magnetic Shielding: The motor structure is magnetically shielded to reduce the potential for electromagnetic interference.

Compression Terminals: The PM210S4 features spring terminals which accommodate pin connectors, single banana plugs, dual banana plugs (standard 3/4" width) or bare speaker wire up to 8 gauge.

VAST Surround: The Vertical Attach Surround Technique (VAST) increases a speaker's effective radiating cone area without increasing the size of the basket.

FlexFit Basket: The Flex Fit frame utilizes slots (where possible) instead of single screw sized holes; allowing slight adjustment of the speaker when mounted.

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

Enclosure: The PM210S4 can be mounted in a sealed or ported box, or in an infinite-baffle (free-air) application. The optimum internal volume of a sealed enclosure is 0.9 ft³ (accounting for the displacement of the woofer), from 0.65 to 1.0 ft³ is acceptable. The 0.9 ft³ enclosure yields a -3dB point of 60.6 Hz. The best ported enclosure volume is 1.4 ft³ using one 4" diameter x 8.5" long port; this yields a tuning frequency of 48.6 Hz and a -3dB point of 40 Hz.
