This public address system has a 2-way coaxial construction with a 6.5" cone driver and a 0.75" liquid-cooled soft-dome tweeter. These speakers produce a more constant sound off-axis because to their coaxial design, which is beneficial in contexts where indirect listening occurs. The drivers themselves are constructed using a high-temperature anodized aluminium voice coil former and a high-temperature voice coil to provide consistent performance throughout many years of operation. It is coated in butyl rubber, which provides additional longevity and acoustic dampening.
