Memphis Audio PRX12FT — 12″ Power Reference Subwoofer (Selectable 1Ω / 2Ω / 4Ω)
The Memphis Audio PRX12FT Power Reference 12″ subwoofer delivers deep, clean bass with unmatched system flexibility. Using FLEX Triple Voice Coil technology, this subwoofer allows you to select 1-ohm, 2-ohm, or 4-ohm impedance via a simple jumper plug—making it easy to optimize performance today or adapt your system for future upgrades.
Overview
Triple-Impedance Flexibility with 12″ Bass Authority
The PRX12FT is engineered for enthusiasts who want powerful low-frequency output without locking themselves into a single wiring configuration. With 400 watts RMS power handling and a 12″ cone, this subwoofer delivers impactful bass while maintaining clarity and control.
FLEX Triple Voice Coil technology makes system configuration simple—allowing quick impedance changes to match amplifier requirements or support future system expansion without replacing the subwoofer.
FLEX Technology
Tri-Flex Selectable Voice Coil Design
Unlike traditional single- or dual-voice-coil subwoofers, the PRX12FT features a Tri-Flex selectable voice coil system. By repositioning the included jumper plug, users can select 1Ω, 2Ω, or 4Ω impedance quickly and easily.
Select 1Ω, 2Ω, or 4Ω impedance without rewiring—perfect for evolving system designs.
Cone & Suspension
Built for Control and Longevity
A black-on-black polypropylene cone is paired with a stitched butyl rubber surround and reinforced spider to ensure consistent cone control under high excursion. This construction supports strong, accurate bass while maintaining long-term durability.
- Polypropylene cone for rigidity and durability.
- Stitched butyl rubber surround for extended life.
- Reinforced spider with improved suspension design.
- Woven tinsel leads for reliable signal transfer.
Thermal Management
DVVC Direct Voice Coil Cooling
DVVC (Direct Voice Coil Cooling) technology actively manages heat during extended high-power operation. By reducing thermal buildup, the PRX12FT maintains consistent performance and helps prevent power compression during demanding listening sessions.
- DVVC cooling for improved thermal efficiency.
- Designed for sustained high-output performance.
- Supports clean bass at rated power levels.
Applications
