No general rule exists for determining the number of CKL SM115 speakers required for a given number
of mid-high enclosures. This will depend greatly on the acoustics of the room or space where the
speakers are to be installed, in particular on reverberation time. Frequently, the reverberation time of
large rooms is very high, meaning that the reproduction of bass frequencies will add "mud" to the sound
quality and will have a negative effect on speech intelligibility. The CKL110 has been designed for
playback of vocal signals in fixed installations. It can be used alone or together with the CKL SM115
(which has the same dimensions and shape) to extend the system's frequency response towards mid
and low frequencies. Alone or together with the CKL SM115 the system offers high efficiency levels. This
makes it suitable for all applications where long throw of voice signals is the main priority.
As a guideline for non-reverberant spaces, never install more than one CKL SM115 for each CKL110. In
the real world, many rooms are highly reverberant. In this case, installing for example 2 CKL SM115 for
8 CKL110 is perfectly enough. It could also be preferable not to install any CKL SM115 if the acoustics of
the room or space are very poor. Our Projects Department will help you out in finding the optimal number
of speaker enclosures that suit your requirements by drawing a virtual model and running a computer
simulation of your project.

6.4. Rigging speaker enclosures

Following general guidelines must be considered:

Always place acoustic enclosures on solid and firm ground

No obstacles should lie between the loudspeakers 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.
The whole CKL range features an effective rigging system, the
same type as used in air cargo shipments (ISO 7166 standard),
consisting in 6 adjustable cargo rails, which allow flying single

enclosures
enclosures. Two rails are placed at each side and two at the rear
wall of the cabinet. The fittings at the side are internally connected
with a metal brace. These side fittings allow flying the enclosure
and linking it to the next row of enclosures. Up to a maximum of 3
rows per column are allowed. Finally, the rear rails allow tilting the
enclosure or group of enclosures.

IMPORTANT

The rear rails have been designed basically for tilting the
enclosures. They should not carry any weight.
ATTENTION
The chains or steel cables used to

always run parallel to the vertical
axis of the loudspeaker cabinet. They must
