Memphis PRX10FT 10" Selectable-Impedance Subwoofer

The Memphis PRX10FT is a 10-inch Power Reference car subwoofer designed for systems that need configurable impedance without changing to a different driver. Its FLEX triple selectable voice coil design supports 1-ohm, 2-ohm, or 4-ohm operation through a jumper-plug setting. This makes it useful for matching a subwoofer to an amplifier's supported load.

Rated for 400 watts RMS and 800 watts peak power, the PRX10FT is intended for a properly matched external car audio amplifier. Its 10-inch format can suit custom trunk, hatchback, or enclosure-based bass upgrades where space is more limited than with larger subwoofers. The compact 5.1-inch mounting depth can also help when planning enclosure clearance.

The selectable impedance design gives installers and system builders flexibility when choosing an amplifier or considering a future second subwoofer. Rather than relying on conventional fixed voice-coil wiring options, the PRX10FT uses a Tri-FLEX configuration that can be changed with its jumper plug. Verify the amplifier's minimum stable impedance before selecting the final setting.

Memphis equips this model with DVVC Direct Voice Coil Cooling technology to help manage heat around the voice coil during operation. The subwoofer also uses a high-temperature TIL voice coil former, an improved suspension and coil design, and woven tinsel leads. These construction details support consistent operation in a correctly configured system.

The black-on-black polypropylene cone, stitched butyl rubber surround, and reinforced spider are designed to provide controlled cone movement and durability. This subwoofer is a practical choice for listeners building a single-sub system or planning an expandable setup. Enclosure selection and amplifier tuning will significantly influence the final bass response.

Key Features

• Tri-FLEX Impedance Selection: Choose 1-ohm, 2-ohm, or 4-ohm operation using the jumper-plug setting.
• 400W RMS Handling: Matches with an amplifier appropriately rated for 400 watts RMS.
• DVVC Cooling: Direct Voice Coil Cooling helps manage thermal buildup during operation.
• Polypropylene Cone: The black-on-black cone provides a durable moving surface.
• Stitched Butyl Surround: The rubber surround supports cone movement and long-term durability.
• Compact Mounting Depth: A 5.1-inch mounting depth helps with custom enclosure planning.

Design & Installation

The PRX10FT combines a black-on-black polypropylene cone with a stitched butyl rubber surround, reinforced spider, woven tinsel leads, and a high-temperature TIL voice coil former. Its improved suspension and coil design are paired with DVVC Direct Voice Coil Cooling technology. The result is a full-size 10-inch subwoofer built around durability, thermal management, and configurable system integration.

Plan for a 9.2-inch cutout diameter and 5.1 inches of mounting depth, while allowing additional clearance for wiring and enclosure construction. Select the 1-ohm, 2-ohm, or 4-ohm setting only after confirming the amplifier can safely run that load, and use an enclosure appropriate for the desired bass character. Professional installation is recommended for proper mounting, wiring, polarity, gain setting, and system protection.
