Loudspeakers 703is 45°. Above the second resonance the impedance rises slowly. It will be seen that the
design of a successful moving coil loudspeaker owes as much to art as science ( Figures
23.21 and 23.22 ). CAD can and does simplify much of the detail work, but after the basic
design parameters (diaphragm size, magnetic fi eld strength, conductor length, etc.) have
been calculated, the nub of the problem is what diaphragm material, adhesives, cradle
material and shape, and so on to use—the art of loudspeaker design is 5% inspiration,
95% perspiration, plus the essential compromise.
