A passive radiator speaker uses a second passive driver, or drone, to produce similar low-frequency extension, or efficiency increase, or enclosure size reduction, similar to ported enclosures. Small [ 28 ] [ 29 ] and Hurlburt [ 30 ] have published the results of research into the analysis and design of passive-radiator loudspeaker systems.

A passive crossover just needs to be connected by wiring to the power amplifier signal. Passive crossovers are usually arranged in a Cauer topology to achieve a Butterworth filter effect. Passive filters use resistors combined with reactive components such as capacitors and inductors. Very high-performance passive crossovers are likely to be ...
