Product Details

Celestion FTR18-4080FD 18" Professional Cast Frame Speaker 1,000W

The Celestion FTR18-4080FD 18" pro woofer features a rigid, yet acoustically optimized cast aluminum frame and a specially treated and weather-resistant cone. Its 1,000 watt RMS power rating is achieved largely by the use of a  4" high temperature Inside/Outside voice coil that efficiently dissipates heat and prevents sensitivity loss through thermal compression. Extensive venting through the frame and motor structure also improves reliability. The FTR18-4080FD's exclusive Flexirol™ surround and double suspension guarantee exceptional linearity, even at the highest excursions.

Celestion FTR18-4080FD 18" Professional Cast Frame Speaker 1,000W
Celestion FTR18-4080FD 18" Professional Cast Frame Speaker 1,000W is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from Great sound, Solid buildI bought this as a replacement for a bad speaker in a QSC KW181. It's very similar to the stock speaker from what I can see except for the dust cap in this one is much smaller and the surround doesn't have as many 'waves' in it. The sound was nearly identical. If anything this one sounded a little 'tighter'. When I ran a sweep on this speaker compared to a stock speaker, this one had a little less low end (about -0.5 db below 80 hz) and a little more high end (about +1.0 db above 90 hz) which was probably due to the dust cap size difference and the fact that this new one hadn't been 'broken in' yet.I do believe this serves as a good replacement in the KW181. I actually prefer the tighter sound when compared to the stock speaker.
