This Listing Includes:

• (1) Synergy SYN Series 15" Dual Voice Coil Subwoofer

Synergy Audio delivers serious daily bass performance with the SYN Series 15" 1250W RMS subwoofer, built for power handling, cooling, and long term reliability. At its core is a massive triple Y35 strontium ferrite magnet motor paired with a bumped T-yoke and extended pole for strong control and efficiency. A high temperature 4 layer 3" voice coil on a black aluminum former keeps power stable under heavy loads, while the multi vented cooling system helps manage heat during hard play.

The non pressed pulp paper cone with red double stitching, high roll foam surround, and dual Nomex spiders give this sub tight, loud, musical bass that holds together whether you’re cruising or pushing it. All of it is mounted in a heavy duty 6 spoke cast aluminum basket finished in gloss black for strength and clean looks.
