Our Statement.
With the CPD 09, KS AUDIO and Innosonix set a new standard:
CPD 09 PoE++ loudspeakers can not only outperform extremely expensive high-end systems in sound quality — they also offer precision-controlled and variable dispersion, remarkable high output, and seamless integration.
All of this delivered through one simple Ethernet cable.
PoE is no longer a compromise.
PoE++ (Power over Ethernet).
The CPD 09 receives its power (PoE++), audio signal (AoIP), and remote control data (Ethernet) — all through a single network cable.
This significantly reduces cabling requirements and saves space, especially in network racks or remote corners of a building. As a result, installation and deployment costs are also lower.
Traditionally, network cables have been used primarily for data transmission and are not designed to carry high currents. This meant that PoE++ could previously only power low-consumption network devices such as phones or access points. However, with the introduction of PoE++ (IEEE 802.3bt), it has become possible to transmit significantly more Power over Ethernet, enough to supply energy-hungry devices.
With the development of the CPD 09 PoE++ amplifier, Innosonix engineers have taken a major step forward. They have succeeded not only in creating an exceptionally powerful amplifier, but one with enormous power reserves, capable of reproducing complex, dynamic audio signals with full detail and stability — even over extended periods of operation.
The result has to be heard to be believed.
CPD 09 - Smart Loudspeaker Technology for Seamless Integration
At KS AUDIO, we understand that modern installations demand more than just great sound, they require smart, scalable, and network-ready solutions. That’s why we developed the CPD 09, a next-generation full-range loudspeaker designed in collaboration with Innosonix GmbH, experts in advanced amplifier, DSP and remote/control software technology.
The CPD 09 delivers outstanding audio performance with features that simplify installation and control:
Power over Ethernet (PoE++) for single-cable connectivity, no external power supply needed
DANTE™ AoIP and full network integration for streamlined audio distribution
Remote management and monitoring for configuration and diagnostics over standard IP networks
Cardioid dispersion even in the mid-low frequencies, reducing unwanted rear sound
Adjustable vertical coverage for precise targeting in complex acoustic environments
Whether for corporate, hospitality, education, or performance venues, the CPD 09 combines cutting-edge functionality with flexible deployment options—making it the smart choice for modern AV integration.
Architecture and Design in the Digital Age
Modern architecture is no longer just about form and aesthetics. In today’s buildings, technological infrastructure plays an increasingly important role.
When designing new office buildings, public facilities, and residential complexes, architects and designers not only consider natural light, spatial efficiency, and sustainability, but also digital connectivity.
A key element of this is the installation of internet and network infrastructure. Already in the design phase, careful planning is given to the placement of server rooms, cable ducts, Wi-Fi access points, and the implementation of Power over Ethernet (PoE), which allows devices such as cameras, sensors, and loudspeakers to be powered and connected through a single network cable.
The CPD 09 is designed specifically to meet the demands of professionals who expect the highest standards in audio production, in every sense of the word.
With the simplest infrastructure, you can now deliver a speech, host a musical interlude, or play pre-recorded music anywhere in a building. No more hauling racks of equipment or large speaker systems.
The CPD 09 is also an outstanding solution for mobile installations. A single, lightweight Ethernet cable is all it takes to conquer even the most complex audio challenges. The speaker includes a 36 mm mounting flange on the bottom for easy use with standard speaker stands, which can optionally be omitted for fixed installations such as the practical carrying handle on top for maximum portability.
The CPD 09 is the versatile tool of choice for the most demanding audio professionals.

VALTEC™ Variable Acoustic Lens Technology – BEAM-STEERING
The CPD 09 leverages the powerful potential of VALTEC™ technology in a unique and purpose-driven way. While our website details the full scope of VALTEC™ and its dynamic influence on wavefront shaping via rotatable acoustic lenses, the implementation in the CPD 09 has been specially optimized for targeted beam control.
In the CPD 09, final wavefront curvature is shaped within the HDSP™ waveguide, making VALTEC™ responsible for managing the initial energy distribution into the waveguide. The rotatable VALTEC™ lenses allow precise steering of the compression driver’s output, directing acoustic energy either primarily toward the upper or lower section of the HDSP™ entrance, or any point in between.
