Santoprene VAST surround, mineral-filled polypropylene cone, vented motor with nano-coated mesh screen, and integrated Deutsch/Amphenol plug-and-play connectors. Compatible with sealed and vented enclosures. IPX6 rated and ASTM B117 and G154 tested. Sold individually (1 each). Backed by a 2 year warranty.

Product Overview

The Rockford Fosgate M1D2-12B is an M1 series 12 inch dual voice coil (DVC) 2-ohm marine subwoofer in black, featuring Color Optix RGB LED illumination controllable via the PMX-RGB controller and RF Connect app (available on iOS and Android, sold separately). It shares the same platform and construction as the M1D4-12B but uses DVC 2-ohm voice coils, giving the VersaSwitch different impedance output settings: 1-ohm (parallel) and 4-ohm (series).

The VersaSwitch allows impedance to be changed between 1-ohm (parallel) and 4-ohm (series) by flipping a single switch, without any additional wiring. Integrated Deutsch/Amphenol connectors are moulded directly into the basket frame, providing error-proof plug-and-play connectivity for both the speaker signal and Color Optix RGB lighting. Conventional zinc nickel-plated marine grade brass spade terminals are also included as an alternative wiring option.

The cone is injection-moulded mineral-filled polypropylene with UV inhibitors, co-moulded with a Santoprene VAST surround. Rockford Fosgate's patented VAST technique increases the effective radiating cone area by up to 25%. A linear synthetic fiber blend spider provides consistent excursion control. The vented motor design with a water-repelling nano-coated mesh screen allows heat dissipation at high output levels while protecting the motor from water ingress. The 100% UV stable ASA plastic frame and grille resist discolouration in marine environments. Optically clear UV stable RGB lighting encapsulation protects the LED PCB throughout.

The M1D2-12B is compatible with both sealed and vented enclosure configurations. Tested to ASTM B117 (500-hour salt/fog), ASTM G154 (500-hour accelerated UV), and ISO60068-2-64 vibration standards. Klippel Verified certification applied. Sold individually - one subwoofer per purchase.

Features & Benefits

VersaSwitch - 1-Ohm or 4-Ohm Without Rewiring: The VersaSwitch allows the DVC 2-ohm voice coils to be configured to parallel (1-ohm) or series (4-ohm) by flipping a single switch. The 1-ohm setting maximises output from compatible mono amplifiers, while the 4-ohm setting suits amplifiers better matched to a higher impedance load.

Color Optix RGB LED Lighting - App Controlled: Ultra-bright wide-angle RGB LEDs are protected by optically clear UV stable encapsulation, controllable via the PMX-RGB controller and RF Connect app on iOS and Android. The PMX-RGB controller is sold separately.

Integrated Deutsch/Amphenol Connectors - True Marine Ecosystem: Moulded in-frame Deutsch/Amphenol connectors combine speaker signal and Color Optix RGB lighting into a single error-proof plug-and-play connection. Zinc nickel-plated marine grade brass spade terminals are also included for standard wiring installations.

Santoprene VAST Surround - UV and Salt-Fog Resistant: The Santoprene VAST surround is co-moulded to the mineral-filled polypropylene cone and attaches vertically using Rockford Fosgate's patented VAST technique, increasing the effective radiating cone area by up to 25% for more bass output from the same 12 inch driver.

Vented Motor with Nano-Coated Water-Repelling Mesh Screen: The vented motor design allows heat to dissipate from the 2 inch (50mm) Kapton voice coil former at high output levels, while the nano-coated mesh screen prevents water from entering the motor assembly in spray-intensive marine environments.

ASTM and ISO Tested - Purpose-Built Marine Construction: Tested to ASTM B117 (500-hour salt/fog), ASTM G154 (500-hour accelerated UV), and ISO60068-2-64 vibration standards. IPX6 water intrusion rating confirms protection against powerful jets of water from any direction.

Compatible With / Goes Well With

The M1D2-12B is suited to marine watercraft, pontoon boats, ski boats, and any vessel requiring a 12 inch marine subwoofer with Color Optix lighting. The VersaSwitch enables pairing with amplifiers rated at 1-ohm or 4-ohm. Sold individually - two units are required for a dual subwoofer installation.

Goes Well With:

• PMX-RGB - Rockford Fosgate Color Optix RGB controller required to access full Color Optix lighting control and RF Connect app integration
• M5-1000X1 - M5 series 1000W marine monoblock amplifier, capable of 750W at 1-ohm and 1000W dynamic - well matched to the M1D2-12B at 1-ohm VersaSwitch setting
• M2-500X1 - M2 series 500W mono marine amplifier for a matched M2 ecosystem pairing
• M5-1500X5 - M5 series 1500W 5-channel marine amplifier for full system builds pairing the M1D2-12B with marine full-range speakers
• M1D4-12B - Black DVC 4-ohm version of this subwoofer (VersaSwitch 2-ohm/8-ohm) for comparison when amplifier impedance requirements differ
• M1D2-12 - White version of this subwoofer for colour-matched installations

Frequently Asked Questions

What is the difference between the M1D2-12B and the M1D4-12B?

Both are black M1 series 12 inch Color Optix marine subwoofers with identical construction, power handling, and physical dimensions. The only difference is voice coil impedance. The M1D2-12B has DVC 2-ohm coils, giving VersaSwitch settings of 1-ohm (parallel) or 4-ohm (series). The M1D4-12B has DVC 4-ohm coils, giving VersaSwitch settings of 2-ohm (parallel) or 8-ohm (series). Choose based on your amplifier's recommended impedance - the M1D2-12B is the better choice for amplifiers designed to deliver maximum power at 1-ohm or 2-ohm loads.

What impedance settings does the VersaSwitch provide on the M1D2-12B?

The M1D2-12B uses DVC 2-ohm voice coils. The VersaSwitch configures the coils to parallel (1-ohm total) or series (4-ohm total) without any rewiring. Use the 1-ohm parallel setting when pairing with an amplifier rated for 1-ohm operation for maximum power output, or the 4-ohm series setting when your amplifier is better suited to a higher impedance load. Contact us if you need help selecting the correct setting for your amplifier.

Is the M1D2-12B sold as a single unit or as a pair?

The M1D2-12B is sold individually - one subwoofer per purchase. If your installation requires two subwoofers, two units will need to be added to the order.

Does the Color Optix lighting require a separate controller?

Yes. Color Optix RGB lighting requires the PMX-RGB controller and the RF Connect app (available on iOS and Android) to access full colour control, lighting effects, and brightness adjustment. The PMX-RGB controller is sold separately. The subwoofer can also be used without the controller at a fixed default colour setting straight out of the box.

Does the M1D2-12B come in a white version?

Yes. The white version is available as the M1D2-12, sharing the same specifications and construction.
