Product Details

Celestion FTR15-3070C 15" Professional Cast Frame Speaker 400W

The Celestion FTR15-3070C 15" pro speaker combines high efficiency with smooth response, backed up by superb reliability. Celestion's expert engineering ensures every operating parameter has been completely optimized, which guarantees faultless performance -- even under the stressful conditions found in pro audio environments. The FTR15-3070C features an Inside/Outside voice coil that is wound on a nearly indestructible fiberglass former. Winding the coil on both sides of the former ensures the stress of thermal expansion is canceled by the opposing masses of copper wire. Accurate and durable, the FTR15-3070C will provide excellent service in direct radiator and horn-loaded applications.
