CPD 10 - HDSP™

By using KS AUDIO own developed HDSP™ waveguide there are two significant differences in comparison to normal CD horns; firstly, the horizontal radiation angle varies depending on the vertical angle, and secondly, the major part of the sound energy is radiated downward in a varies curved wavefront towards the audience, and not towards the walls or the ceiling. 

Several acoustic principles were combined in order to achieve this. The energy of the high-frequency driver is formed in a waveguide with varying path lengths to a vertically curved line, which is then radiated into a horn with a width of 120° in the lower part and 60° in the upper part. 

In the transition to the low-mid frequency membrane, the sound signal is electronically delayed and phase corrected in such a way that the main inclined radiation axis is sustained over a wide frequency range. Likewise, the crossover frequency is selected in a way that the bundling resulting from the diameter of the membrane is equivalent to that of the mid-high frequency horn. 

The CPD 10 compliments the KS CPD-Series compact 2-way systems with its small dimensions, and the unique directivity of HDSP technology. The result is consistently even hi quality audio dispersion with the highest sound pressure level, while simultaneously having the lightest weight possible. The power capacity equals this quality: The 10′′-long excursion low-mid speaker can handle 700Wrms and the 1.4′′ driver 100Wrms.

With the CPD 10, particular attention has been paid to a correct transition in dispersion of the HF unit and the 10” woofer. Within the entire dispersion range of the CPD 10, the listener experiences a straight frequency response over the entire bandwidth of the speaker. This is unique for any speaker but very special with the complicated dispersion behaviour of the CPD 10.

Both the 10′′ LF driver and the 1.4′′ HF driver have strong but light Neodymium Magnets. The 3′′ diaphragm of the compression driver consist of a special aluminum alloy that has a clearly reduced distortion factor in comparison to a titanium diaphragm. With the CPD 10, KS AUDIO has res- ponded to the demanding needs of the professional sound engineer with a universally usable 2-way sound system with the highest audio quality, yet in a compact size. There are many applications in which it can be used: Theatre, Live-stage Music, in large rooms or tents, as a delay system for far away areas, or as a compact mid/high system in conjunction with any KS AUDIO sub woofer.

The rear mounted, separately housed, 2-way PWM + MOSFET Controller /amplifier operates without the need of a cooling fan thus avoiding the typical fan noise found in most amplifiers. The electronically balanced analog in/out and AES/EBU section is equipped with XLR F+M connectors. The unit is controlled via digital rotary knob, menu configuration shown on LCD graphic display. All adjusted levels, filters, and delay- settings are permanently saved.

Once more KS AUDIO presents an improvement: Audio Over Ethernet direct from your console or PC into the
active loudspeaker via DANTE™ option! Furthermore, every Loudspeaker can be addressed to an adjustable IP address, and over the same network all functions of the system

can be monitored and controlled via KS AUDIO REMOTE software.

The speaker cabinet construction is, like all KS AUDIO systems, built from birch plywood with an extremely robust charcoal colored Polyurethane coating. At your request the finish can be changed to any desired color from the RAL color charts. Another special feature are the two multipurpose fittings on the back of the speaker. Allowing the installation of different fly-ware and connectors, which are safely interlocked by means of quick release ball-lock-pins. There is a pole mount in the bottom of the cabinet and a protective steel grill on the front, with acoustic foam.
