Performance And System Integration

The TRS-1800 gives users precise control over their system with a variable crossover (60Hz–200Hz), volume adjustment, and two EQ modes – Flat for accurate reproduction and Shape for extra low-end enhancement. The onboard limiter and protection circuitry maintain clean performance at any volume, while phase reverse and ground lift switches ensure compatibility and noise-free operation in different venues and setups.

Construction And Build Quality

Designed to withstand the demands of live use, the TRS-1800’s cabinet combines a 15mm plywood body with an 18mm MDF baffle for strength and acoustic stability. Finished in rugged black spatter paint, it’s complemented by a heavy-duty steel grille with acoustic foam backing for added protection. The integrated 35mm pole mount allows easy setup with full-range tops, while its well-ported design maximises low-frequency efficiency without unwanted resonance.
