The TRx218N is our finest and lightest dual 18-inch subwoofer. The high power, light weight Neodymium 18-inch woofers feature 4-inch voice coils with a total power capacity of 1600w/3200w peak. Not only does it provide thunderous bass—the system weighs 10 kgs less compared to similar ceramic systems. The TRx218N is the ideal match to the TRx153N for a 4-way system. Stack two TRx115’s, TRx215’s, or TRx153’s side by side on a side stacked pair TRx218’s for 120 degrees of uninterrupted coverage at optimum head level placement. The enclosure is constructed of CNC machined multi-ply Hardwood with heavy gauge steel powder coated front grills. The crossover includes 4 pin NL4 Speakon connectors mounted on FR4 double sided circuit boards for solid construction and durability.
