2,000 to 18,000 Hz response with 106 dB sensitivity.

“With more and more of our OEM customers utilizing multi-driver horns, or combinations of small format woofers and high frequency drivers in line array columns, there was a clear demand for a high quality mini driver,” says Ron Tizzard, Director of Sales B&C Speakers.
The Florence, Italy, company details the 1” exit DE110 features a 36mm, high temperature polymer diaphragm “with unique ribs that smooth the frequency response above 8,000 Hz, resulting in very flat response curve from 2,000-18,000 Hz. Even with this small footprint, the DE110 is rated for a respectable 50 watts of program power, 25% more than the previous generation offered by B&C.”
