Your interpretation is correct.
With the same cost,
for long distance such as studio / outdoor, active speaker performs better. It is because passive speaker uses line power which has big power and signal loss over distance. Also, active speaker has built-in amp which doesn't need matching.
for short distance such as home, standalone amp with passive speaker is preferred. Standalone amp has good space for versatile circuits (power supply, filters, equalizer, volume control). Moreover, power loss is insignificant for short distance.
About the speaker driver unit, there is no design difference between active and passive speakers. |
