Product Details

B&C 18TBX100 18" Woofer

The industry-standard B&C Speakers 18TBX100 features a 1" long/4" diameter copper wire voice coil with high thermal capability, and a ventilated magnet assembly, both of which contribute to low power compression. A very low distortion figure is obtained using a double spider design and dual demodulation rings in the magnetic path. The 18TBX100 is fortified by a proprietary water-proof cone treatment that facilitates safe use in adverse climatic conditions. This benchmark pro subwoofer driver is found in many famous manufacturers' well-established loudspeaker enclosures.

B&C 18TBX100 18" Woofer
B&C 18TBX100 18" Woofer is rated 4.875 out of 5 by 8.
Rated 5 out of 5 by from There's a reason why this driver is everywhereThe 18TBX100, and some OEM variants, show up in a ton of subwoofer designs. The reason is that it sounds fantastic, gets loud, and is exceptionally reliable. I use them in 8 ft^3 cabinets tuned to 35Hz with a 30Hz high-pass filter, with excellent results.If you're using RCF L18P300's, and sending them in for recones regularly, you might want to bite the bullet and try a couple of these. You won't regret it.
