ACOUSTICAL DESIGN ASPECTS

We try to reduce early room interaction as much as possible, and thereby avoid unwanted coloration of sound. The KAD K5 speaker system is designed to beam music towards the listener and to keep it away from the surrounding walls, floor and ceiling as much as possible. This benefits the musical experience at the listening position, and the soundstage will become more lively and transparent.

The KAD K5 system is based on one guiding sound directivity principle known as the d’Appolito MTM configuration for the mid-range (MF). The mid-woofers thereby extend to a cross-over frequency low enough to hand over to a double sub-woofer pair at the rear of the K5 cabinet.

DIGITAL TO ANALOGUE CONVERSION (DAC)

Each KAD K5 speaker system uses four separate D/A conversion channels for optimized signal- to-noise performance. Two 32-bit/384kHz DACs are used for that purpose, one DAC chip is managing the MF/HF driver section and one DAC chip drives the double rear LF driver section;

CLASS-D AMPLIFICATION

The motor in the K5 speaker system is formed by three separate channels of amplification delivering upto 1000 Watt-rms @ 1%THD-N in total. The Class-D amplification is of high-end quality and performs under normal listening conditions at less than 0.005% harmonic distortion.

DRIVER FREQUENCY CROSS-OVER FILTERING

The purpose of the multi driver concept of the KAD K5 system is to ideally create a source agnostic loudspeaker, capable of reproducing Classic, Jazz or pure acoustic Voice recordings with utmost precision and transparency and of course the K5 does not shy away from Techno or Rock music either. Paramount to achieve this goal is to have optimal phase and frequency alignment of all driver units, virtually working together as one. The KAD K5 speaker system uses cross-over frequencies at 80 Hz (LR 24db/oct) for the LF drivers and 2.3 kHz (256 tap FIR ~180dB/oct) between the MF and HF drivers.
