Features

Rear-Loaded Transmission Line Design: The SU121TL G2 utilizes an efficient rear-loaded transmission line design that delivers extended low-frequency response with tight, controlled bass — ideal for large-scale sound reinforcement in both indoor and outdoor venues.

1800W RMS Power Handling at 8Ω: With a real 1600W–1800W RMS power capacity, the SU121TL can handle intense audio demands with consistent performance. It’s well-suited for concert touring, festivals, and demanding fixed installs.

Heavy Braced 25mm Birch Cabinet: Crafted from vibration-resistant 25mm thick birch plywood, the enclosure is heavily braced to minimize unwanted resonance and maximize energy transfer — ensuring superior sound quality even at high SPL levels.

Touring-Grade Finish: The enclosure is finished in a tough, black rubberized PolyUrea coating that protects against wear, moisture, and scratches. It’s built to endure the rigors of professional use in the most demanding environments.
