Karat Reference 2 DC Technical Information Continued

In this section, you'll find a scan of the R2 DC network (out of the PCB program EAGLE).

On the left you can see the midrange network with impedance correction and 12dB band pass. In the mid you'll find the tweeter network with a 12dB high pass and also the impedance correction. On the right side the bass network is shown. It contains our DC technology (12dB high pass) and a 12dB low pass.

There you can see that it is a "normal" passive network with one board for every route. There are a lot of components on the board because of the low internal losses and the high power capability we wanted to reach. And this is possible only by using huge inductivities and resistors and capacitors in parallel or series arrangement.

DC (displacement control) is a development of Canton that prevents the woofer above sub harmonic (inaudible) waves and compensates the roll off of the driver as shown in the picture below. This is a picture that explains the comparable SC technology (because I've no picture about the DC technology). The difference between DC and SC is that DC is a "passive version" and SC is a "active version " ( with operational amplifiers) in for example half active solutions like our Ergo RC-A.

With the DC technology we are able to reach a lower -3dB cut off frequency at the same enclosure volume or otherwise a smaller enclosure at the same cut off frequency compared to speakers without this technique. And because of the lower excursion of the diaphragm at frequencies below the cut off frequency the driver is able to produce a higher maximum sound pressure level.
