These SOUND PROJECTORS feature almost the sound pressure of a horn speaker but have a wide-band such as a dynamic speaker system. Both of them (CS-015 and CS-030) have installed a top-quality „twin-cone“-speaker chassis and a high-quality matching transformer, which are specially equipped for outdoor use.
That is why it is also ideally applicable for pretentious and professional voice and music reproduction outside, e.g. outdoor swimming pools, sports fields etc.
It is possible to rig up a number of these sound projectors, on top of each other, by using similar phasing of the signal connection. This effects a narrowing of the vertical  transmission angle at 1/4/8 kHz, which has the same effect as a column speaker.
Of course the CS-015 and CS-030 are also able to be connected at low-impedance. It is only necessary to connect the built-in matching transformer to the appropriate wire bond).

Please consider the following features:

• Both models have a very attractive design and are made of a shock- and scratch-resistant plastic.
• The colour is creme white, similar to RAL 9001.
• The impedance matching is done very easily by clamping on the appropriate leads of the connection multi-core.The leads are marked appropriately and cannot be confounded.
• By simply changing the plug connections on the matching transformer, the speaker can also be used at low-impedance (8 ohms).
