The SUB PA 240 was developed to support the PA 110 H. The PAW 46, 46-cm (18“), woofer used here with its large, six-way vented voice coil, is of a design which enables it to work at high output levels and still maintain clear, precise sound. In the recommended cabinet, it manages a very impressive sound pressure of 95 dB (1w/1m) at 30 Hz lower limiting frequency.
The large-format bass reflex tube effectively suppresses flow losses and flow noise. In order to provide the necessary rigidity of the cabinet, a number of strengthening braces are required.
