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 AMAZING PERFORMANCE!!!!I was looking at these for about a year before I broke down and got one, I wish I hadn't waited that long. I have been using Eminence Omegas in some scoop cabinets. I tend to worry about them because our 5 piece band gets pretty loud and I don't have a sound guy. The worry is over. These go so much lower and have better overall tone than the Omegas. 2000 watts is no problem thrown at one of these. This one sub sounds better than the pair of Omegas. The Eminence Omega subs have been good to me over the past couple years, but this B&C is showing me love I don't deserve!!!! The cone that is weather treated front and back is 3 times as thick as the Omega and with the high BL factor it performs awesome in the folded scoop. I loaded it in a JBL SR4718 cabinet and ran it at the last show I played and it sounded so sweet, punchy and tight at any volume. It eats up 2100 watts from my Crown amp no problem. I can't wait to get the next one. Check the reviews on any B&C component!!!!! Thanks Parts Express for the free delivery. They always get the stuff to my house 2 days after I order!!!!

Rated 5 out of 5 by from Great Upgrade for the Cerwin-Vega EL36cI took the advice from Stewards Productions and upgraded my EL36c cabinets and the difference is unbelievable. The sound quality is much better and they are WAY louder.

Rated 5 out of 5 by from BassI replaced the original drivers in my cerwin vega EL36B cabinets with these speakers and they out perform even the cervin vega afterburners, I run 6 of these in a sportsbar club and the bass is so intense it has shaken the bricks outside of the building loose from the mortar. Truly wouldn't use anything else and i have yet to blow any of these driers since i started using them.

Rated 5 out of 5 by from TBX 100 in Folded Horn Cerwin Vega CabI had brought these subs to replace the EL-36 Cerwin Vega subs that I had. I decided to buy 2 of the B&C 18tbx100 subs since they had a lot mor power handling I'm running a 2 Crown XTi amps 1600 Bridge at 8 ohm to each 18tbx100 sub and it was like wow a lot of clean bass.

B&C 18TBX100 18" Woofer

Confused about Watts for this speaker. Prts Expss says Power Handling RMS 1200w, Power Handling max 2400w. B&C says Nominal Power Handling 1200w, Continuous Power Handling 2400w. What Power amp? 1200w or 2400w. Thought RMS & Continuous was same meaning.

Asked by: JeB3
Some companies rate RMS and peak, other companies will have RMS, continuous (or program) and peak. RMS is measured via sine wave so its accuracy in the real world is limited. Continuous in this case is "program power" which means under normal conditions, music, vocals, etc. In reality, any amp rated between 1200 and 2400 watts will be plenty for these drivers.

Will this Sub fit in JE-36 enclosures? I have a couple cabinets I'm not using and would like to get some usage out of them.

Asked by: HydraSounds
The sub will work in the enclosure, you will have to verify the actual dimensions for fitting.
