Memphis PRXE12SFT 12" RGB Ported Loaded Enclosure

The Memphis PRXE12SFT is a loaded, ported subwoofer enclosure built around a single 12-inch Power Reference woofer. It provides a ready-to-install bass foundation for vehicle audio systems that need low-frequency output without designing a separate enclosure. The compact cabinet format helps simplify a subwoofer upgrade by combining the woofer and enclosure in one assembly.

This enclosure is designed for listeners who want a single-subwoofer solution with adaptable amplifier matching. Its FLEX selectable-impedance design supports 1-ohm, 2-ohm, or 4-ohm configurations, allowing the system to be tailored around a compatible mono amplifier. The enclosure is factory configured at 2 ohms, while other impedance selections require access to the woofer wiring.

With a 400-watt RMS and 800-watt peak power rating, the PRXE12SFT is intended for an amplifier matched to its continuous power capability and selected load. The front-firing rectangular port directs output toward the cabin. A plastic port flare is used to promote smoother airflow and help reduce audible port noise.

The loaded woofer uses an RGB LED cone accent, and the Memphis logo on the baffle is also RGB illuminated. This gives the enclosure a coordinated lighting feature while retaining a conventional carpeted enclosure appearance. The lighting can be hardwired to a 12-volt source or used with a compatible optional RGB controller.

The PRXE12SFT fits systems where enclosure space, amplifier load flexibility, and integrated lighting are all considerations. Its trapezoidal cabinet measures 22 inches long by 15.5 inches high, with 14-inch top depth and 16.5-inch bottom depth. A single set of spring-post terminals accepts speaker wire up to 10 AWG for connection to the amplifier.

Key Features

• Single 12-Inch Loaded Design: Combines one subwoofer and a matched ported enclosure.
• FLEX Selectable Impedance: Supports 1-ohm, 2-ohm, or 4-ohm system configurations.
• 400W RMS Handling: Provides a continuous-power target for amplifier matching.
• Front-Firing Port: Directs bass forward through a rectangular vent.
• Plastic Port Flare: Helps smooth airflow and reduce vent noise.
• Integrated RGB Lighting: Illuminates the woofer cone and Memphis logo.

Design & Installation

The enclosure uses an MDF cabinet wrapped in black carpet, with a front-firing rectangular port and molded plastic flare. Its loaded PRX-series woofer uses a black polypropylene cone, stitched butyl rubber surround, reinforced spider, woven tinsel leads, and a high-temperature TIL voice-coil former. The cabinet holds one 12-inch woofer and uses a single terminal cup with spring-post speaker connections.

Confirm the available vehicle space before installation using the listed 22 x 15.5 x 14 x 16.5-inch enclosure dimensions. Match the amplifier to the enclosure's 400-watt RMS rating and the selected 1-, 2-, or 4-ohm load; the factory configuration is 2 ohms. Changing impedance requires removing the woofer to access its wiring, and RGB operation requires the included harness to be connected to 12-volt power and ground or to an optional compatible RGB controller.
