Together with the CKL enclosure you will find a 4-way SPEAKON® cable connector. Always respect
polarity.
Make sure to securely plug in the SPEAKON® connector, i.e. fully inserting it to the socket and rotating
it to the right until noticing the locking mechanism.
6. AMPLIFICATION
6.1. Operation of one or two pairs of CKL110 speaker enclosures
Any amplifier capable of delivering an output power between 350W and 700W is perfectly suitable for
driving a pair of CKLs. Eclers amplification lines include several power amplifier models which can
perfectly fulfil this task. In case of operating two speaker enclosures in parallel, the required output
power of the amplifier should lie between 700W and 1400W at 4
Ω
.
This enclosure has been designed for the reproduction of voice signals mainly. If the enclosure is to be
installed in an acoustically deficient space (poor intelligibility, highly reverberant), it is recommended to
use an external active filter with a cut-off frequency lying between 140 and 170 Hz, keeping the high-
pass signal. 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.
Remember that the CKL110 includes a passive filter which separates mid and high frequencies.
