The TRx2218 is our powerful Dual 18-inch subwoofer system. The high power, 18-inch woofers features a 4-inch voice coil with low temperature high peak power capacity. The box is designed with four deep large corner located ports producing a very strong structure, and coherent sub frequency output vertically and horizontally. The added strength rigidity of the corner ports puts all the force of the speaker out the front and into the room, and not wasted on the walls vibrating. This provides the idea low frequency coupling in multi box clusters, both in the horizontal and vertical positions.

The TRX2218 features foot locating holes on top for stacking another TRx2218 and for stacking up to 4 TRx3210 line array elements without hardware. Top centered pole mount for suspending a TRx2115 or TRx12N. The enclosure is constructed of CNC machined 13-Ply Premium Russian Baltic Birch with heavy gauge steel powder coated front grills. The crossover includes two 4 pin twist lock high current connectors mounted on FR4 double sided circuit boards for solid construction and durability.
