Loudspeaker System

General Description: Technical Specifications:

The Electro-Voice® TX1122 is a high power, 2-way loudspeaker sys­tem that can be used in a variety of applications where high quality
sound reinforcement is required in a lightweight package.

The TX1122 utilizes the DH3, a high output 1.25” titanium compres­sion driver, coupled to a Constant Directivity™ 90° x 50° horn. This
combination results in a smooth response to 20 kHz and excellent
pattern control in short to medium throw applications.

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 24 dB/octave slopes with equalization for
very smooth response in vocal range, extended HF, and a protection
circuit for long term reliability.

The TX1122 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 EVCoatTM 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
the TX1122 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 the TX1122 to be used with the TX1181 subwoofer for
extended sub bass on a single amplifier channel, with no additional
processing needed.
