Commentary
A 38 cm coaxial speaker unit that combines a 38 cm cone woofer and a 13 cm cone tweeter.
Since there is no built-in network, it must be used in a Model3125 dividing network with a crossover frequency of 1.2 kHz or in a multi-amplifier system.
An enclosure with an internal volume of 113 to 170L is most suitable, and a bass-reflex enclosure and a back-load horn 4530 are most suitable.
