Celestion FTR15-4080F 15 Inch 600 Watt Raw Frame Speaker
CELESTION 15 AND 18 600 WATT FTR SPEAKERS:

OVERVIEW:
These drivers feature innovations in magnet and chassis design, and voice coil material; significant technological advances that minimize distortion and thermal compression to further increase performance, power handling and sound quality.

DESIGN FEATURES:
Low Thermal Compression - voice coil overheat can cause output SPL to diminish over time. FTR's sophisticated design focuses on thermal control enabling heat to be conducted rapidly away from the voice coil assembly, minimizing this effect.

Low Distortion - FTR significantly improves upon the distortion performance of many LF drivers in production today. This has been achieved through an innovative magnet structure, evolutionary voice coil construction and an optimized chassis design.

High Power - FTR enables first-class sound reinforcement and can handle up to 1000 Wrms (AES Standard). This level of power handling requires a large voice coil, which in turn demands a substantial magnet. The cast aluminum chassis is robust enough to support a larger magnet and has been painstakingly designed to dissipate more heat away from the voice coil.

DESIGN CONCEPT:
"Overcoming distortion and thermal compression are major challenges for anyone designing industry-leading, professional loudspeakers", commented product development director Ian White. "By focusing on the key areas of magnet, chassis and voice coil, we've created a new kind of driver that represents an evolution in technology to achieve very high levels of performance."
