The CLAM21041 is a line array module for fixed installations.
The specially designed horn and wave guides flattens the sound waves to a perfectly non-delayed symmetrical wave front with a 110 x 15 dispersion pattern.
The passive construction allows for economical use of external amplifiers and DSP processors, (available presets in all our processors and amplifiers with built-in dsp´s)
Since the CLAM line array are designed only for fixed installations, we have omitted all external features like handles, advanced tour-friendly hardware etc, to reduce manufacturing and materials cost, so that the module can perform like the most expensive tour line arrays, but cost a fraction, the splay tilting hardware was designed to be easy to use, safe and economical.

Most hardwares for line arrays are designed for tour and rental applications,
with versatility and “on-the-road” thinking, resulting in very expensive hardwares, usually costing as much as 20% of the actual speaker, this is of very little use in fixed installations.
We have also looked into how line arrays often are installed, and the CLAM21041 are actually two line array modules in one cabinet...
Each driver and woofer has a perfect alignment, resulting in a seamless linear wave front.
The cabinet were designed to be as shallow as possible (only 280 mm.) knowing that depth is often a problem when installing Line arrays.
