The close-coupled dual 15” HH woofers, 1600W amplifier and over-rated power supply give impressive depth and volume. The full frequency response and high sound pressure ensure the Tessen 2151 excels as a complete standalone system for FOH or sidefill applications, but it’s equally happy working with the TNS-1800 sub in larger rigs.
