Celestion FTR, the pro audio heritage of a legendary brand
While Celestion is iconic among guitarists, the FTR series showcases its expertise in professional sound reinforcement. The FTR15-3070C fits this lineage: a 15-inch woofer designed for demanding sound reinforcement, combining efficiency, power handling, and consistent performance.
Intended uses and users
Ideal for stage subwoofers and full-range PA speakers, DJs, bars/concerts, and mobile systems, this 15-inch driver suits contractors, knowledgeable DIY speaker builders, and integrators seeking a reliable 8-ohm woofer capable of handling 400 W while maintaining precision in the low-mid range.
Design and key technologies
Cooling and stability
The voice coil with a specific design improves heat dissipation. Result: less power compression and reduced distortion, even during extended high-level use.
Glass fiber cone
The glass fiber composite limits unwanted resonances and resists humidity, ensuring a cleaner response and increased durability in varied environments.
Aluminum chassis and controlled magnetism
The aluminum chassis stiffens the assembly while controlling vibrations. The ferrite magnet provides predictable and robust behavior, perfectly suited for sound reinforcement applications.
