Bring powerful, full-bodied bass to your classic without sacrificing space. The RetroSound® R-TW84 is an ultra-thin 8-inch subwoofer engineered for vehicles where every inch counts. With a mounting depth of just 2 inches, it’s the perfect solution for classic cars and trucks that have limited room for modern audio upgrades.
Built around a rigid cast aluminum basket and driven by a high-performance neodymium magnet structure, the R-TW84 delivers tight, accurate low end that complements your music rather than overpowering it. A durable polypropylene cone and Santoprene® surround ensure smooth, natural bass reproduction, while the 1 3/4-inch voice coil with Kapton® former keeps performance consistent under heavy load.
Optimized for sealed enclosures from .12 to 1 cubic foot, this subwoofer adapts easily to under-seat, behind-seat, or custom-fit installations, giving you flexibility without compromising sound. With 250 watts RMS (500 watts peak) of clean, controlled power handling, the R-TW84 brings modern performance to your classic ride in a design built for tight spaces.
Pair It with the Technophonic 5-Channel Amplifier
For the ultimate setup, match the R-TW84 with the RetroSound® Technophonic 5-Channel Class D Amplifier. This powerhouse delivers dedicated subwoofer output along with four full-range channels to drive your entire system. Together, the Technophonic and R-TW84 create a seamless balance of clarity and low-end punch — perfect for enthusiasts who want modern performance without taking away from their vehicle’s classic character.
