Constant impedance volume controls.
L-Pad attenuators are used to adjust the output levels of speakers somewhat like a volume control. The basic internal configuration of an L-pad is a ganged network of two variable power resistors, one in series with the speaker and the other in parallel thus providing a constant impedance regardless of their setting; this allows fine tuning and balancing of multiple unit systems. As the impedance remains constant, the crossover is unaffected.
Though primarily associated with midrange and treble drivers, the higher powered L-Pads can be used to control low frequency drivers; many of our customers use these in guitar amplifiers.
We stock 4 ohm, 8 ohm and the elusive 16 ohm versions.
