Despite its small frame size, the CPD W2 reproduces the lowest frequencies in an accurate as well as powerful way.
The construction is classic – 2 × 15′′ vented cabinet design of superior quality.
What makes the CPD W2 very special are two high-capacity long-excursion speakers with 100mm voice coils and fiber-reinforced membranes, as well as the construction of the waveguide for frequencies in the range of 40Hz.
The cabinet is inside divided into two independent chambers that suppress standing waves and wall resonances efficiently. At the same time, operating reliability is increased since the two speakers are acoustically dampened separately. However, the ventilation ports apply to both chambers, which results in a higher sensitivity and lower distortion levels due to the minor flow velocity at the tunnel walls.
The slim appearance of CPD W2 makes it either particularly suitable for applications with limited room availability or smart integration into a wall niche or stage portal. Furthermore, explicit the tall enclosure design simplifies lifting mid-high cabinets onto an optimum stacking height.
In the CPD W2 a DSP controlled amplifier is embedded as a slide-in module in the rear panel. It provides the required performance, response correction and safe protection for the loudspeaker. The power stage is designed to be particularly efficient and works without cooling fans, using “cold” PWM technology. The wide-range switching power supply is capable of handling all AC voltages between 110V and 240V. The inrush current is limited by electronic control. Connection is provided via PowerCon F+M connectors which allow daisy-chaining, e.g. to the full-range speaker.
The symmetrical input has XLR F+M connectors. There are 2 channels avail- able, so that the bass content from a stereo signal can be reproduced via a single mono woofer. Another special feature is the automatic recognition and changeover of a pending digital audio signal according to AES/EBU standard. Apart from the power switch, the following additional control elements are available: buttons for “sensitivity” for individual adaptation to the operating site, for delay settings in m and ms, low-pass filter or selection of the digital audio channel. The settings are clearly legible on self-luminous displays.
Further settings, such as a parametric equalizer, can be downloaded and saved via integrated Ethernet switch by the KS REMOTE software.
