The M1D4-12B 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 setting when pairing with an amplifier rated for lower impedance loads for maximum output, or the 8-ohm 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 M1D4-12B? The M1D4-12B is compatible with both sealed (1.65 cu.ft / 46.72 litres) and vented (2.45 cu.ft / 69.38 litres) enclosure configurations. A sealed enclosure delivers tighter, more accurate bass with a shallower roll-off, while a vented enclosure produces more output at the tuning frequency with a steeper low-frequency roll-off below the port tuning point. Choose based on your installation space and preferred bass character. What is the difference between the M1D4-12B and the M2D4-12I? The M1D4-12B is the M1 series 12 inch DVC 4-ohm subwoofer in black, compatible with sealed and vented enclosures, using a Santoprene VAST surround and linear synthetic fiber blend spider. The M2D4-12I is the premium M2 series 12 inch DVC 4-ohm infinite baffle subwoofer, optimised for free-air hull mounting without an enclosure, featuring ASTM-tested construction and industry-first moulded in-frame connectors. The VersaSwitch settings also differ: M1D4-12B switches between 2-ohm and 8-ohm, while M2D4-12I switches between 2-ohm and 8-ohm as well. Choose the M1D4-12B for sealed or vented enclosure builds; choose the M2D4-12I for infinite baffle installations where no enclosure is available. Is the M1D4-12B sold as a single unit or as a pair? The M1D4-12B 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.Legendary Products & Support From Authorized Dealers When you choose Frankies BrandBeast, you're choosing quality and performance.
