Product Details

Celestion FTR15-4080F 15" Professional Cast Frame Speaker 600W

A workhorse 15" pro woofer, the Celestion FTR15-4080F utilizes a large 4" diameter voice coil and massive 110 oz. ceramic ferrite magnet to generate class-leading motor strength. Extensive attention has been paid to thermal management, and Celestion's experienced engineers incorporated multiple ventilation paths to cool the motor assembly and achieve top performance. The FTR15-4080F's 22 mm long voice coil winding helps it achieve a 10 mm Xmax rating, which helps to explain the driver's prodigious bass output and low distortion. Parameters have been optimized to provide excellent results in pro audio enclosures of all types.

Need screw hole spacing info - Ready to Purchase

I want to use the Celestion FTR15-4080F 15" Woofer as replacement speakers so it is critical that the 8 equidistant holes match up. The old KLH woofer spacing is 14-7/8 inches diameter (on center) between any pair of screw holes. Will this work? I have the same question for the Dayton ND140-8 5-1/4" Aluminum Cone Midbass which I am going to order separately because it is not in stock. In this case I am replacing KLH midrange speakers in which the 4 equidistant hole spacing is 4-11/16 inches diameter (on center) between any pair of screw holes.
Asked by: Sanity Seeker
The center-to-center distance between mounting holes is approximately 14-5/8, and the holes are slightly oblong, about 1/4" long. The ND140-8 has a specification sheet available on the right-hand side of the product page, under "Manuals/Resources." The mounting holes for that driver will be on a 138mm (approx. 5-7/16") circle. While we most likely do have replacement drivers that would provide excellent performance for you, matching up the mounting patterns can be extremely difficult if not impossible. In most cases, one would simply resign one's self to drilling new screw holes; the alternative would be scouring the second-hand market for direct replacement parts.
