The Memphis Audio MJM812 is a high-performance 8-inch "MOJO Mini" subwoofer designed to deliver massive, competition-grade bass from a compact footprint. It is specifically engineered for installations where space is at a premium—such as under-seat truck boxes or small hatchbacks—without sacrificing the aggressive output the MOJO line is known for.
Key Features
-
FLEX™ Selectable Impedance: This subwoofer features Memphis's patented FLEX technology, allowing you to switch between 1-ohm and 2-ohm impedance using a simple jumper plug. This "future-proofs" your setup, making it easy to add a second sub later or match the power requirements of different amplifiers without rewiring.
-
V-Groove Surround: The double-stitched rubber surround uses a unique V-Groove design that maximizes the effective surface area of the cone. This allows for extreme excursion (Xmax) and higher air movement, resulting in deeper, louder bass than typical 8-inch drivers.
-
Direct Vent Voice Coil (DVVC) Cooling: To handle its high power rating, the MJM812 uses DVVC technology and an integrated aluminum heat sink to rapidly dissipate heat from the 2-inch 4-layer copper voice coil, ensuring reliable performance during long, high-output listening sessions.
-
Robust Build Quality: The subwoofer is built into a vented cast aluminum basket and features a fiberglass-reinforced paper cone with a lightweight, ultra-rigid glass fiber dust cap for minimal distortion at high volume.
