The efficiency or sensitivity, which is sound pressure level (SPL) at 1m and 1W power input, is
105dB. The maximum SPL produced at 1m reaches 136dB SPL.
The maximum RMS power is 600W RMS at 8, while the program power capacity is 1200W at
8.
DPC118 LOUDSPEAKER CABINET (CKL7000T, CKL5000T and CKL3000T systems)
Low-dimensioned loudspeaker cabinet for low frequency playback. Bandpass type acoustical
design. Assembled with 18 mm thick birch plywood from Finland covered with a scratch and shock
resistant polyurethane paint finish.
It employs a high performance 18'' speaker attached to a horn in order to increase efficiency. The
speaker is protected against shocks, dust and splashes by a metal grille and an acoustically transparent
foam. Provided with 3 lateral handles.
The efficiency or sensitivity, which is sound pressure level (SPL) at 1m and 1W power input, is
106dB. The maximum SPL produced at 1m reaches 140dB SPL.
The maximum RMS power is 1100W RMS at 8, while the program power capacity is 2200W at 8.

3. INSTALLATION

3.1. Placement and mounting

As a general rule and due to its portable conception, staking
loudspeaker cabinets is the recommended way of setting CKL-T system.
This means mounting CKL100T (i.e., CKL7000T system) on top of CKL
SM115 cabinet and this on top on DPC118 units.
The bass reinforcement cabinets DPC118 should be paired so that
their marks are face to face (see diagram).
Bass enclosures are more efficient when placed directly on the floor
in landscape orientation rather than vertical for a better sound quality.
Additionally, the acoustic conditions of the venue as well as the
audience number, should be taken into account. Following general
guidelines must be considered:
Always place acoustic enclosures on solid and firm ground.
No obstacles should lie between the loudspeaker and the audience. High frequencies, as
opposed to low frequencies, tend to be much more directional and any obstacle in the acoustic wave
path represents attenuation in the frequency response of the system. For large audiences better sound
propagation will be obtained if loudspeaker cabinets are placed in a higher position.
Avoid exposing the system to sun for long periods and to rain.
