Driver component w/crossover
When you see the DAD-1 driver, it looks like a tweeter …and it really is. But beyond its appearance it does much, much more than any other tweeter design out there.
Originally, the HDSS® (High Definition Sound Standard) model TWEP51 was and still is offered as a pair of these tweeters for use in automotive applications. Then it was discovered that one of these drivers added to the center channel in home theater sound systems would miraculously clear up unintelligible dialog; so an introduction to that market was initiated through this website.
Using patented ETL™ (Embedded Transmission Line) technology, the DAD-1 driver is critically damped for its full bandwidth and void of diaphragm breakup. This normalizes acoustic impedance and maintains proper dispersion for the bandwidth of the driver. No metal or unnatural material is used for diaphragm breakup control with a dome employing silk material for its natural damping qualities.
Without getting into cross-over networks and the way a conventional tweeter performs in a given 2-way loudspeaker system, the DAD significantly augments overall sound clarity for virtually anyone who, through aging, suffers a natural loss of hearing acuity, especially in the higher frequency range. The five significant things that enhance the overall performance of the interfaced loudspeaker with which it is used are:
1) Increases clarity in the 3.5 – 4 kHz range where human hearing has its greatest sensitivity
2) Forces the integrated speaker to be sympathetic at this range and smooths out its frequency response throughout its entire range
3) Enhances the dispersion characteristics of the speaker - facilitates off-axis imaging (allows “sweet spot” listening anywhere in the room)
4) Enhances and clarifies sound stage imaging
5) Provides the fast impulse response for lower frequencies to provide the proper character for bass sounds.
