Overview
Engineered for high-performance low-frequency applications, the Celto Pro 18SW1500-8 redefines the limits of seismic bass control and ultra-high excursion. Featuring 1500 W RMS (AES) power handling and a sensitivity of 97 dB (1W/1m), this premium transducer delivers exceptional efficiency in demanding acoustic environments.
The 4-inch (100 mm) dual-layer (inside/outside) copper voice coil is wound on a Dupont GFB fiberglass former with 240°C PI insulation, ensuring maximum thermal stability under continuous heavy loads. With an impressive ±13.25 mm Xmax and 62 mm peak-to-peak mechanical limit (Xmech), it guarantees distortion-free, stable, and powerful low-end reproduction. Distributed in Turkey by Trioacoustic, the 18SW1500-8 is the ultimate engineering choice for touring systems, high-end installations, and premium subwoofer designs.
