Memphis Audio MBE8D12 Dual 8" Ported Subwoofer Enclosure

The Memphis Audio MBE8D12 is a loaded ported subwoofer enclosure with two 8-inch MB Series subwoofers. It provides a compact way to add dedicated low-frequency output to a car-audio system without designing and building a separate enclosure. Its narrow 6.3-inch depth can suit installations where space is limited.

This enclosure is intended for listeners who want a ready-to-install bass foundation while retaining flexibility in amplifier selection. Memphis FLEX Technology allows the system impedance to be configured for either 1 ohm or 2 ohms. This gives installers a choice when matching the enclosure to a compatible mono amplifier.

The MBE8D12 is rated for 700 watts RMS and 1,400 watts peak power handling. Its specified sensitivity is 84. The side-loaded port is part of the enclosure design and is intended to support strong bass output from the dual 8-inch configuration.

Memphis builds the enclosure from 100% MDF and finishes it in custom stitched carpet. A high-current, nickel-plated compression terminal provides the speaker connection point. These details support a clean, purpose-built installation rather than an exposed component-subwoofer setup.

For an under-seat or down-firing application, the included rubber feet can be fitted to the 8-inch enclosure. The loaded design means the subwoofers and enclosure are already matched as a single assembly. Add a compatible amplifier, appropriate wiring, and a properly configured signal path to complete the system.

Key Features

• Dual 8-Inch MB Subwoofers: Delivers a complete dual-subwoofer bass enclosure in one package.
• FLEX Technology: Selects between 1-ohm and 2-ohm system impedance.
• 700-Watt RMS Rating: Supports amplifier matching using continuous-power guidance.
• Side-Loaded Port: Uses a ported enclosure layout for bass output.
• 100% MDF Enclosure: Provides a rigid cabinet material for the loaded system.
• Included Rubber Feet: Supports optional down-firing placement on 8-inch models.

Design & Installation

The MBE8D12 uses a 100% MDF enclosure with a side-loaded port, custom stitched carpet exterior, and a high-current nickel-plated compression terminal. It measures 20 inches long, 14 inches high, and 6.3 inches deep, with a 6.3-inch bottom depth. The compact dual-8-inch format is designed as a finished loaded enclosure rather than a bare box.

Measure the intended mounting space before installation, including clearance for the side port and wiring at the terminal. Choose the 1-ohm or 2-ohm FLEX configuration only with an amplifier designed to operate at that load, and set amplifier gain appropriately for the enclosure's 700-watt RMS rating. The included rubber feet may be installed when using the enclosure in a down-firing application.
