Product Details

B&C DE38 1" Neodymium Mylar Horn Compression Driver 2-Bolt

B&C's smallest high performance 1" horn driver ever, the DE38 1" features a low-mass Mylar diaphragm, aluminum voice coil, and optimized neodymium magnet assembly. Compact yet powerful, the neo motor's small size facilitates use in miniature speaker system designs, as well as providing a solution to the critical high frequency component spacing issues presented by line arrays. 1" horn throat diameter, 2-bolt mounting.

Specifications: • Power handling: 40 watts RMS/80 watts program above recommended crossover of 2 kHz/12 dB slope • VCdia: 1.5" • Impedance: 8 ohms • Frequency response: 1,500-20,000 Hz • SPL: 107.5 dB 1W/1m • Dimensions: 2.75" diameter x 2.2" depth • Net weight: 1.1 lb.

B&C Speakers' line of compression drivers is the result of a continuous research effort, dedicated to refine every component in the structure, and their overall balance. Diaphragms are made of titanium, mylar, or polyimide, in order to get the required results in efficiency and bandwidth. Their shape and structure is mathematically evaluated well before building the first prototype. Afterwards, their performance is tested with methods that range from modal analysis to laser vibrotomy.

All voice coils are of the edgewound ribbon type, and made of aluminum to reduce mass and achieve the best electro-acoustic performance. The magnet assembly is designed and optimized with up-to-date software for Finite Element Analysis (FEA) and complemented, where needed, by a copper cap to improve frequency extension and linearity.

Equal care is taken in the design of phase plugs, whose role in enhancing performance and reducing distortion artifacts is critical for compression drivers. The precision and transparency of B&C compression drivers is constantly improved by the progress in acoustical modeling and simulation.

B&C DE38 1" Neodymium Mylar Horn Compression Driver 2-Bolt
B&C DE38 1" Neodymium Mylar Horn Compression Driver 2-Bolt is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from One great driver!I purchased two of these drivers to use on my Transylvania power company "The Tubes". The frequency response of these drivers on my waveguides is excellent. Don't let these small drivers fool you they are very sensitive and will play very loud. The Mylar diaphragms are so much softer sounding than titanium or aluminum. If you don't like the harsh sound of titanium or aluminum these are the drivers for you. I would say the build quality of the drivers is very good. I have had these drivers now for a few months and they sound better each day as they break in. These would be a great retrofit to replace out of date drivers.

Rated 5 out of 5 by from Great Smooth HF DriverI bought this high frequency driver to upgrade my QSC HPR 122i after being dissatisfied with the HF projection and lack of presence of its original HF driver. After searching for options that have the right physical fit and acoustic response, I decided to give this DE38 a try. Swapping out the compression driver was a snap, a drop-in fit. After I finished the swap and turn on for audio test, I was pleasantly surprised by its smoothness and clarity. Wow, this driver made the QSC HPR122i came to life. I might add that the Mylar diaphragm is quite different from the Titanium/aluminum diaphragm HF drivers I'm used to. It's smooth response does not have the metallic sound of harshness. (some higher order THD) The speaker now can be pushed to higher SPL without hurting the ears. I am really glad I have this upgrade.
