Speaker Breakup
(Full version, TDM Only)
The Speaker Breakup slider lets you specify how much distortion is produced by the current speaker model. Increasing the Speaker Breakup setting adds distortion that is a combination of cone breakup and other types of speaker distortion (emulated by the speaker cabinet model). Range is from 1 to 10.
Below certain frequencies, the speaker cone vibrates as one piece. Above those frequencies (typically between 1 kHz and 4 kHz), the cone vibrates in sections. By the time a wave travels from the apex at the voice coil out to the edge of the speaker cone, a new wave has started at the voice coil. The result is comb filtering and other anomalies that contribute to the texture of the overall sound.
