Eminence Speaker has struck up an exclusive license agreement with Evenstar, a wholly owned subsidiary of SLS Audio, to use and sub-license its new D-fend technology within the professional audio and musical instrument markets. D-fend is an all-digital, programmable loudspeaker protection and attenuation circuit designed to solve the problems associated with protecting loudspeakers from excessive power conditions. Incorporating such features as digital signal processing with onboard digital filtering, customizable microprocessor and MOSFET construction, the D-fend protection circuit reportedly enables a designer to use this technology prior to passive filtration and allows different sensitivity settings in specific frequency bands, such as woofer over-excursion bands or high-frequency peak damage regions.
