Fostex Loudspeaker L-Pads

We stock two models of the Fostex L-pad range, a 100W version and a 200W version. The purpose of the L-pad is to adjust the relative volume of drivers connected to them by adding resistance in series and parallel, thus maintaining a constant 8-ohm load impedance.

The fundamental internal structure of an L-pad consists of a combined network of two variable power resistors. One resistor is connected in series with the speaker, while the other is in parallel. This configuration ensures a consistent impedance regardless of the resistor settings. Consequently, it enables precise tuning and balancing of multi-unit systems. Importantly, as the impedance remains constant, the crossover remains unaffected.
