7.10. Electromechanoacoustical circuit

The complete circuit for a loudspeaker in a bass-reflex enclosure is obtained by combining Figs. 6.4(b) and 7.23. To do this, the acoustical radiation element of the circuit labeled “2M _M1” in Fig. 6.4(b) is removed, and the circuit of Fig. 7.23 is substituted in its place. The resulting circuit with the transformer removed and everything referred to the acoustical side is shown in Fig. 7.24.
