If you've been debating an upgrade to your sound system, the time has come to ditch those dusty old speakers from the '80s. With the SRT Series, experiencing incredible sound, cutting-edge performance, and reliability is a no-brainer.

A True Workhorse for Gigging Professionals
The SRT18S Subwoofer features a 1600W Class D amplifier designed for ultra-reliable, consistent performance. Its custom high-efficiency transducer ensures maximum punch. It increases the efficiency of your full range loudspeakers by taking care of the low end for the entire system. This woofer is Built-Like-A-Tank to conquer every gig, yet lightweight enough for easy loading.

Custom Voicing Presets
  • Flat - Natural balance between deep bass and overall output
  • Deep - Emphasizes low-end frequencies. Great for dance, rap, and electronic music
  • Punch - Prioritizes highest possible output level. Great for bands and rock music

Optimize for Your System
The SRT18S has variable crossover frequency, a polarity invert switch, defeatable front LED, stereo or mono-summing for single or dual subwoofer deployment, and variable level control (-6dBU to +6dBU).

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're sending audio that's a bit too hot, the speaker will cool it down. The SRT18S uses a Universal Power Supply (100-240VAC) with Power Factor Correction for stable operation with unstable AC power.
