6.2. Operation with more than two pairs of CKL speaker enclosures
In case of working with 6, 8, 10 or more speaker enclosures, we recommend using a 2-channel amplifier
for each 2 or 4 speaker enclosures. The low level audio signal should be distributed from amplifier to
amplifier through their stack outputs. For this reason it is important to check if the amplifiers offer this
stacking possibility. All Ecler power amplifiers have this feature. Further considerations mentioned in the
previous paragraph also apply.
6.3. Installation of CKL110 with CKL SM115 bass reinforcement enclosures
As mentioned earlier, the CKL SM115 represents an ideal complement for the CKL110 in all those
situations where it is necessary to extend the frequency response of the system towards the bass end,
consequently improving the reproduction of music signals. This speaker enclosure does not include any
passive filter, meaning that the use of an external active crossover with tunable crossover frequency and
minimum filter slope of 18dB/oct (recommended 24dB/oct) is necessary. Inside Eclers product range,
two products can fulfil this need: The FAP30L, 2-way stereo crossover with limiter or the UCM20 board,
which can be directly installed inside the back of the APA series of power amplifiers.
The recommended crossover frequency is 150Hz.
