The CPD SUB produces the frequencies that your ears expect in large spaces: Not only at 80Hz with a 4m wavelength, but also one Octave deeper while retaining constant and efficient upper low frequencies. Like any KS AUDIO speaker system, CPD SUB has a high audio-quality that is not compromised by its power.
This is achieved by using four heavy duty, 10”- long excursion woofers with a 30 mm voice-coil. Low moving mass combined with Push-Pull technology produces a precise in-and out transient response. The drivers are paired in 2 separate, specially engineered enclosures with exact acoustically tuned properties. This minimizes any possible distortion.
The speaker cabinet itself has very little vibration due to its strategically reinforced plywood construction. Input mono sum as a standard.
The speaker cabinet construction is, like any KS AUDIO system, built from birch plywood with an extremely durable PU-coating. All RAL colors available. Handles, an M20 pole mount, and protective grill, with or without acoustic foam, are further features of this premium product. The rear mounted DSP-controller / PWM amplifier operates very efficiently without the need of a – sometimes distractingly loud - cooling fan. The FIR crossover and filter are specially matched to the drivers, with corresponding compressors and limiters to ensure safe operation. Electronically balanced in/outs via XLR F+M connectors. In addition to the power switch, the control panel also has a selectable digital volume / delay control to individually adjust for each venue and offers a digital delay reaching up to 40 m for decentralized PA systems.
With 2-Channel redundancy, the volume control allows for adjustment with a range of +/-9dB. Another special feature is the DSP Controller with its integrated Delay. Which allows hands-on adjustment, or the creation of a focused directivity Bass-array without any additional equipment. The limiter prevents overloading, provides for frequency response correction, and has a Subsonic-filter. The integrated PMW controller-amplifier can be remotely controlled via Ethernet connection by KS AUDIO REMOTE 3 software.
