Its architecture targets solid and controlled bass, ideal for reinforcing the tonal foundation of a full-range system.
Who Is It For and What Venues?
The TS18S is aimed at DJs, bands, contractors, and installers seeking a compact yet impactful powered subwoofer for clubs, concert halls, corporate events, or outdoor venues. It delivers the essential low-end foundation for today's shows while ensuring perfect coherence with active satellite speakers.
What Makes the Difference on Stage
Power and Control
The Class D amplification provides a comfortable dynamic headroom, while the 18-inch driver with a 3-inch voice coil handles peaks without strain. The result: sharp impacts, tight bass, and effective projection even at high levels.
DSP and Connectivity
The "Speaker Use" presets allow EQ adaptation to the context. Phase alignment facilitates coupling with your active speakers for a homogeneous acoustic summation. Professional connectivity simplifies integration in mono or stereo setups.
