Each woofer has a long excursion voice coil and suspension, plus a 14 Oz. magnet, providing high output capability. Uniform response of the woofer is over 2.5KHz with use of the Dual Frequency™ crossover network. One woofer is directed forward while the second woofer is directed upward, which helps create a balance of reflected and direct energy in the listening room. TWEETER: Four 3" wide-range high sensitivity tweeters per enclosure provide flat power radiation beyond 15KHz. The response extends down to 1.5KHz for use with the Dual Frequency crossover network. Two tweeters in each speaker enclosure are directed outward so that most of the sound energy is reflected off the back and side walls. One tweeter is positioned so that the sound energy is directed towards the center of the room and the final tweeter is positioned to reflect sound off the back wall between the speakers and into the room, providing a strong center stereo image by filling the "hole in the middle". DUAL FREQUENCY CROSSOVER NETWORK: Located in the top woofer cup, the crossover network consists of two capacitors, two resistors, and two tweeter protection lamps. The Dual Frequency crossover network is designed to offer performance advantages by deliberately operating both the woofers and tweeters simultaneously over a significant part of the frequency range. Crossover network to have separate transition frequencies for the woofers and tweeters. By using separate frequencies, an overlap in response of almost one octave is achieved, providing smoother frequency response in the crossover region. Careful design of all components in the crossover network matches woofer and tweeter response, eliminating phase cancellation and assuring accurate frequency and transient response.
