The SMX2120 12" woofer has an FEA optimized magnet structure for very low distortion and maximum intelligibility at high SPL levels. The crossover uses steep 24dB/octave slopes with equalization for very smooth response in vocal range, extended HF, and a protection circuit for long-term reliability.

It has a variety of features that make it equally suited for portable or fixed installation applications. The trapezoidal enclosure is constructed out of a combination of plywood and MDF, and coated with EVCoat for maximum strength while still remaining lightweight. The unique grille design is very strong, dent resistant, and features a rotatable logo. Four-way handles allow for gripping in a variety of positions, a pole mount allows for placement on a subwoofer or a tripod. Six 3/8" threaded points allow a single TX1122 to be suspended in a various positions. The recessed input panel with dual NL4 connectors keeps the connectors hidden, while allowing it to be used with the TX1181 subwoofer for extended sub bass on a single amplifier channel, with no additional processing needed.
