Celestion's next generation of professional loudspeakers, FTR has now been extended to encompass two new models.

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

"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 which can be adapted to fit a wide range of applications."

FTR15-3070E is a 15" diameter, long throw, 400W Low Frequency (LF) driver with a 3.0" voice coil. FTR15-4080HD is a 15" very long throw, 1000W LF driver with double suspension for extra excursion control.

Conceived and developed at Celestion's facility in Ipswich, England, FTR provides:

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