A CLASSIC FORMULA. AMPLIFIED.

V-GROOVE MDF CONSTRUCTION
This advanced cabinet-building technique uses CNC-machining to create precise panel joints that make enclosure assembly more efficient and exact.
EASY INTEGRATION
Integration to OEM and aftermarket head units is a snap, thanks to a variety of input options and automatic turn-on capability (via signal sensing or DC offset sensing).
QUICK DISCONNECT
A quick-disconnect power connector makes it easy to remove the subwoofer when you need extra space.
COMPACT, SEALED ENCLOSURE DESIGN
This subwoofer system is designed to deliver amazing sub-bass from an enclosure that is only 6.625 inches (168 mm) deep. Its low-profile enclosure design has been carefully engineered to the optimum sealed enclosure alignment for the 12TW1 driver and has been fine-tuned through extensive real-world listening.
TW1 SUBWOOFER TECHNOLOGIES
DMA-OPTIMIZED WOOFER
Proprietary motor, suspension and cone modeling systems are used to achieve long, linear excursion capabilities with low distortion and powerful sound output.
CONCENTRIC TUBE SUSPENSION DESIGN
This unique design allows the motor system to be placed higher in the cone body — further compressing depth while still permitting excellent mechanical excursion.
TAB-EAR FRAME DESIGN
This design reduces the driver’s overall dimensions, allowing it to be mounted in a space similar to that required by the next smaller round woofer frame.
ENGINEERED LEAD-WIRE SYSTEM
Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.
