B&C 18TBX100 1200W LF Driver
B&C Speakers is a major supplier to the pro audio market in midrange, woofer and subwoofer cone drivers. We have made a strong commitment to provide a well-balanced line of LF drivers that range from 6” to 21” .
We have made refinements in our cone geometry, magnet assemblies and speaker production lines to create a dynamic and powerful lineup of speakers. The models that are included in this catalog all have:
- increased sensitivity
- increased power handling capacity
- increased excursion capabilities
- lower distortion levels
Our engineers have optimized each design with Finite Element Analysis (FEA) software to ensure each speaker operates to its fullest potential time and time again.
As one of the leaders in the development of neodymium woofers for the pro audio market, we first launched the HPL series 10 years ago. Based on its success, we have created three series of neodymium woofers (NDL, NW, SW). New baskets have been designed to maximize the power handling capacity, Xmax, and heat dissipation.
The NDL series works with an inside slug of high-energy neodymium magnet assembly. It has been developed with a new ventilated magnet assembly to assist the cooling of the voice coil. The NDL woofers strike a balance between light weight and performance. We have expanded the line to include 3” voice coil versions that offer tremendous weight savings yet are extremely powerful and durable to handle the power requirements of the pro audio market.
The NW series features a very highenergy neodymium ring magnet assembly. We have carried over similar basket designs as the TBX series but created 4” voice coil versions for the 12”, 15” and 18” woofers. The new 4” coil woofers are rated at 1000W. The NW series ranges from an 8” woofer up to an 18” subwoofer. A specially designed double silicon spider is utilized to create excellent excursion control and minimize the distortion levels. Superb bass performance in small box applications are one of the key strengths of the NW series.
The SW series is the next generation of neodymium magnet subwoofers. We focused our energy on long, large diameter voice coils (115-150 mm) for greater power handling capability and low power compression. In addition, we have developed new suspension systems to offer superb linearity with low DC offset, and excellent durability.
From nightclubs, to stadiums, to concert halls around the world, our speakers are chosen based on their reliability, consistency and most of all for their outstanding sound quality. B&C Speakers is front and center in the development of cone speakers.
