CPD W15 Powered | T4 W Unpowered Subs

The CPD W15 / T4 W subwoofer is another powerhouse packed full of KS Audio innovation. The speaker cabinet is a classic reflex design -- 2 x 15” -- driven by a 1,200W rms PWM amplifier. What makes the CPD W15 unique is the highly durable long throw driver with a 100 mm voice coil and reinforced cone, plus a directivity for frequencies in the range of 40Hz. The two bass reflex openings, like on our other CPD subs, is highly efficient, with minimal distortion at the tunnel openings.

Despite its powerful output, the CPD W15 is still reasonably sized--making it an excellent choice for venues with little space available. With an M20 threaded pole mount, the CPD W15 becomes an ideal stand base--it is the perfect low frequency extension when used in combination with the CPD 15 top box, bringing it to the ideal audience height.

The CPD W15 also features KS Audio's excellent implementation of Audio Over Ethernet--direct from your console or PC and into the active loudspeaker. For years, audio engineers have looked for a better solution for how to send real-time audio over a network. In a large fixed installation, it is normal to use an audio network. However, correct set up of the system takes experience, and in the normally short setup times of touring, a mistake-free setup is nearly impossible. This is especially true in theaters, opera houses, and live sound stages, where constant modification and adjustment, grounding issues, lighting dimmers, and questionable cables make a standard setup impossible. However, it does not need to be so complicated: you can install a network with quality off-the-shelf components. On your menu, your active loudspeakers will be given a channel number, and you assign your PC or digital mixer to transmit the output signals on these channels. You can setup your loudspeaker anywhere in your network and always have it immediately on the same output.

No need for searching, new patches, or diagrams for the next build-up, and no disturbances in the network audio signal. Installation of audio over a data network cannot be easier--it truly becomes plug and play. With 16 audio channels on one cable, it saves setup time and significantly reduces system costs, as ethernet cables and connectors are much less expensive than standard analog multi-core cables and connectors. If you want to continue to work with your current console but it has no direct network access, KS Audio offers a 19" single rack space module that converts any ADAT signal into a compatible network audio signal. Furthermore, every loudspeaker can be assigned an adjustable IP address, and over the same network all functions of the system can be monitored and controlled with the PC Remote 3 software.

Every component in the system also has the latest technology: neodymium magnets, a wide-range switch mode power supply with PFC, PWM, and FET amplifiers, as well as digital signal processing with FIR filters. The electronically balanced analog and AES/EBU inputs are in the form of XLR connectors, with an active output. The unit is operated through a menu, using a digital rotary knob, and an LCD graphic display. All adjusted levels, filters, and delay settings are permanently saved. The rear mounted, separately housed, PWM Controller / amplifier operates without the need of a cooling fan, thus avoiding the typical loud noise found in most self-powered systems.The speaker box construction is, like all KS Audio systems, built from birch plywood with a polyurethane coating.

T4 W: Same as CPD W15 but unpowered.
