Speaker system

Abstract

In a speaker system employing a bass reflex or Kelton type cabinet intends to solve deterioration in efficiency of a speaker caused by an increase in impedance otherwise occurring on both sides of the antiresonance frequency, and to improve the sound radiating efficiency. The speaker system comprises a plurality of dual-voice-coil speaker units (20) which are attached to a bass reflex or Kelton type cabinet (50) and made up of first voice coils (21) connected in parallel to each other with the same polarities joined into one terminal and second voice coils (22) connected in parallel to each other with their same polarities joined into one terminal, and one impedance compensation circuit (10) connected in series to the plurality of second voice coils, which are connected in parallel to each other, for thereby keeping constant the input impedance as a parameter of the speaker system.
