PROBLEM TO BE SOLVED: To provide a speaker system, where a Kelton type woofer is configured in a cabinet, which can produce a low frequency sound with a sufficient sound pressure even when the cabinet is downsized. SOLUTION: In the speaker system of this invention where the inside of the cabinet 1 is partitioned by a 1st partition wall 2 and a 2nd partition wall, a 1st acoustic chamber 15 is formed by the inner wall of the cabinet 1 and the 1st partition wall 2, a 2nd acoustic chamber 16 is formed between the 1st partition wall 2 and the 2nd partition wall 12, and a 3rd acoustic chamber 17 is formed between the inner wall of the cabinet 1 and the 2nd partition wall 12. A squaker/tweeter 3 is placed in the 1st acoustic chamber 15, and a woofer 5 is fitted to the 2nd partition wall 12. The 3rd acoustic chamber 17 is open to the outside of the cabinet 1 via a duct 4. The thickness of the 1st partition wall 2 is determined so as to be bent by a sound wave emitted from the woofer 5.
