The black RCF TTS 18-A II is an 18" 2800W active subwoofer designed to provide low-frequency reinforcement for A/V system installers, audio engineers, and DJs in outdoor environments or houses of worship, concert venues, and live stage applications. Its Class-D amplifier delivers 2800W of power to the 18" woofer, which produces a frequency response of 30 to 400 Hz and is hyper-vented for heat dissipation.
32-bit DSP processing yields simple adjustment of input gain, delay, and crossover presets. RDNet control via EtherCon I/O allows comprehensive remote parameter control and system monitoring. XLR and powerCON inputs and outputs are employed for straightforward integration with standard PA components.
The TTS 18-A II boasts a sturdy wood cabinet, built-in carry handles, and M20 pole sockets for tour readiness.
