Key Features The Technophonic provides a dedicated sub channel with enough headroom to drive the R-TW84 to its full potential, while also powering your main speakers. The R-TW84 has a mounting depth of just 2″, making it ideal for tight spaces under seats, behind panels, or in custom enclosures. The Technophonic uses full-range Class D digital circuitry for high dynamic range and low distortion. The sub output delivers 225 W RMS at 4 Ω (330 W RMS at 2 Ω) to your R-TW84. The R-TW84 sports a neodymium magnet, a rigid cast-aluminum basket, polypropylene cone, and Santoprene® surround for clean, durable bass output.
