Satnet 480 - CDT Audio 2 Way Midrange, Tweeter Crossovers

Features:

Satnet 480 is an upgrade of Satnet 456 with an extra set of terminals for an image tweeter. This operates in parallel the main tweeter. Both are protected. The film capacitors are larger. Level control is by slide switch instead of jumper.

The passive crossover has a very important job in the component speaker system. It needs to divide the duties of precise musical reproduction to the appropriate speakers without introducing any phase shifts or distortion into the music.

Engineering a perfect complement to the highly acclaimed High Definition drivers was an equally challenging task taking months of research with both laboratory and real-time listening testing. The "Phase Perfect" crossovers, called SatNet, are an engineering breakthrough for car audio. They use a very ingeniously designed fifth order, elliptic type network that creates very distinct advantages over conventional "Butterworth" or "Linkwitz-Riley" passive filter topologies. This crossover topology is so unique that this is the VERY FIRST TIME it has ever been used commercially in a car audio application.

Rather than try to use some commercially available "me too" crossover design that blends speakers about as well as trying to fit a square peg in a round hole, we chose to step ahead in crossover design. You won't find this design in any other car audio component speaker system, period. Technically speaking, the SatNet crossover design is a fourth order/24 dB per octave design supplemented by a series first order/6 dB per octave on the front end.

The unique combination of the two creates a virtual 10th order or 60 dB 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. That makes for a much more natural sounding component system, as if it were that one perfect speaker. The steep roll off of the SatNet crossover also means more power handling for the tweeter and less chance for damage from low frequencies. This means you have less chance of blowing up the tweeters when turning up the volume.

Other less sophisticated passive crossover designs use automatic resetting capacitors, circuit breakers, or even small light bulbs that "soak the power" to make up for the lack of correct power transfer to the tweeters.

You won't find any light bulbs in the CDT "Phase Perfect" High Definition Crossovers. What you will find is the ideal link to some of the best car loudspeakers you'll ever listen to, the CDT High Definition Speaker Systems.
