1600W CLASS-D Amplifiers

SRT Series Loudspeakers equipped with our most rock-solid amplifier platform ever for better performance across the board than any other loudspeaker in its class. Ultra-efficient power combined with sophisticated protection and monitoring makes SRT the ultimate workhorse.

Advanced Impulse DSP - Proprietary Acoustic Tuning

Years of audio nerds tweaking settings and lugging around test equipment has paid off, and you get to reap the benefits. With our Advanced Impulse DSP, muddy midrange, harsh highs, and sloppy bass simply do not exist with these speakers. Not only does SRT sound incredible directly in front of them on-axis, they sound just as good all the way to the edge of their coverage, unlike other typical loudspeakers.

Custom SYM-X Horn

The custom-designed Sym-X horn combined with a custom high-frequency driver provides an almost razor flat response (within +/- .5 dB), and that carries through the crossover point to the woofer for midrange that sounds clear and accurate even at high SPL.

Wireless Linking

Want to get some music playing through your system quickly? How about on-the-fly adjustments to your pair of loudspeakers? With SRT, it's a piece of cake. Just pair your two SRT Series speakers together, then control and stream music to them right from your phone. They can act as a stereo L/R or be split up as a dual-zone system with separate level controls.

Transparent System Protection and Monitoring

SRT Series Loudspeakers utilize a sophisticated combination of input limiting, multi-band compression, temperature monitoring, and signal analysis to keep the amplifier and transducers safe.

Transparent System Limiting and Protection

A dedicated processing module monitors and protects the amplifier in real-time. Sound quality and tonal balance is maintained even under heavy limiting. Input limiting keeps your source signal in check so if you are sending audio that’s a bit too hot, the speaker will cool it down. Universal Power Supply (100-240VAC) with Power Factor Correction for stable operation even with unstable AC power.
