Product Overview

The Rockford Fosgate M1D4-10B is an M1 series 10 inch dual voice coil (DVC) 4-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 M1 series platform and construction as the M1D4-12B but in a more compact 10 inch format, with smaller sealed (1.1 cu.ft) and vented (1.45 cu.ft) enclosure requirements suited to vessels with less available space.

The VersaSwitch allows impedance to be changed between 2-ohm (parallel) and 8-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.

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 - 2-Ohm or 8-Ohm Without Rewiring: The VersaSwitch allows the DVC 4-ohm voice coils to be configured to parallel (2-ohm) or series (8-ohm) by flipping a single switch, enabling flexible amplifier matching without additional wiring or soldering.

Compact 10 Inch Format - Smaller Enclosure Requirements: The M1D4-10B fits a sealed enclosure of 1.1 cu.ft (31.15 litres) or a vented enclosure of 1.45 cu.ft (41.06 litres), making it well suited to under-seat compartments and space-constrained vessel installations where the larger M1D4-12B cannot fit.

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 10 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 M1D4-10B is suited to marine watercraft, pontoon boats, ski boats, and any vessel requiring a compact 10 inch marine subwoofer with Color Optix lighting. The smaller sealed (1.1 cu.ft) and vented (1.45 cu.ft) enclosure requirements make it the better choice over the M1D4-12B for space-constrained installations. The VersaSwitch enables pairing with amplifiers rated at 2-ohm or 8-ohm. Sold individually.

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, compatible with the M1D4-10B at both 2-ohm and 8-ohm VersaSwitch settings
• 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 M1D4-10B with marine full-range speakers
• M1D4-10 - White version of this subwoofer for colour-matched installations
• M1D4-12B - Larger M1 series 12 inch black DVC 4-ohm subwoofer for installations with more enclosure space

Frequently Asked Questions

What is the difference between the M1D4-10B and the M1D4-12B?

Both are black M1 series DVC 4-ohm Color Optix marine subwoofers with the same VersaSwitch settings (2-ohm parallel / 8-ohm series), power handling (300W RMS), and construction. The M1D4-10B is the 10 inch version with a shallower 4.23 inch mounting depth, smaller sealed (1.1 cu.ft) and vented (1.45 cu.ft) enclosure requirements, and a higher Fs of 37Hz suited to a smaller enclosure volume. The M1D4-12B is the 12 inch version with a deeper 6.65 inch mounting depth, larger enclosure requirements, and a lower Fs of 27Hz for deeper bass extension. Choose the M1D4-10B where space is limited; choose the M1D4-12B for maximum bass depth.

What impedance settings does the VersaSwitch provide on the M1D4-10B?

The M1D4-10B uses DVC 4-ohm voice coils. The VersaSwitch configures the coils to parallel (2-ohm total) or series (8-ohm total) without any rewiring. Use the 2-ohm parallel setting when pairing with an amplifier rated for 2-ohm loads for maximum output, or the 8-ohm series setting for amplifiers better suited to a higher impedance. Contact us if you need help selecting the correct setting for your amplifier.

What enclosure types are compatible with the M1D4-10B?

The M1D4-10B is compatible with both sealed (1.1 cu.ft / 31.15 litres) and vented (1.45 cu.ft / 41.06 litres) enclosure configurations. A sealed enclosure delivers tighter, more accurate bass while the vented enclosure produces more output at the port tuning frequency. The smaller enclosure volumes compared to the 12 inch models make the M1D4-10B a practical choice for vessels with limited storage compartment space.

Is the M1D4-10B sold as a single unit or as a pair?

The M1D4-10B 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.
