ES-200US - CDT Audio 2-way Crossovers with UpStage Technology Built-In

Engineering a perfect compliment to the highly acclaimed CDT drivers was an equally challenging task. "The Elliptic" crossovers, called SatNet, are an engineering breakthrough for car audio.

They use an ingeniously designed fifth order, elliptic type network that creates very distinct advantages over conventional "Butterworth" or "Linkwitz-Riley" passive filter topologies. This topology is so unique that this is the VERY FIRST TIME it has been used commercially in a car audio application.

Technically speaking, the SatNet crossover design is a fourth order/24dB per octave design supplemented by a series first order/6dB per octave on the front end. The unique combination of the two creates a virtual 10th order, 60dB per octave crossover where the critical crossover point between the mid and tweeter is.
The benefits of the design are many. First, the power transition between midrange and tweeter is virtually identical. Phase response problems and polarity shifts are almost entirely eliminated. What you HEAR, is a much more natural sounding component system, as if it were that one perfect speaker. And further engineering improvement are our "Transient optimized"
designs which you find in the 560-200Z,200US and HEX-5000.

All combined, you have the ideal link to some of the best car audio loudspeakers you'll ever listen to.

This versatile crossover module implements a two-way crossover with large high quality parts or alternately may be programmed to drive an upstage high mounted second tweeter. This dual functionality is jumper selectable. In simple two-way mode the tapped inductor of the Satnet 560 is used. Dual jumpers moved together change the crossover to upstage mode. In the upstage mode the drive to the mid-woofer and tweeter are tapered off to interface with the upstage tweeter. This tapering is adjustable with three L settings and two C settings. This alters the crossover frequency and response shape (damping). The image tweeter furthermore has seven selectable levels available. This compact silver bullet module implements the upstage system while holding complexity to an absolute minimum. Upstage crossover is typically at 8kHz. Main tweeter crossover is at 3.7kHz. No protectors are used.
