A three-way speaker comprises a high frequency transducer, a mid-frequency transducer, a low frequency transducer, and a hollow speaker cabinet defining a pyramidal mid-frequency transducer compartment and a low frequency transducer compartment isolated from the mid-frequency transducer compartment. The high frequency transducer is mounted in a first hole of the cabinet opening in the low frequency transducer compartment, the mid-frequency transducer is mounted in a second hole of the cabinet opening in the mid-frequency transducer compartment, and the low frequency transducer is mounted in a third hole of the cabinet opening in the low frequency transducer compartment. Therefore, the isolated mid- frequency transducer compartment and low frequency transducer compartment also isolates the mid-frequency transducer from a displacement of air produced by the low frequency transducer in the low frequency transducer compartment. This prevents the mid- frequency transducer to produce distortion caused by this displacement of air. Also, the pyramidal mid- frequency transducer compartment improves the performance of the mid-frequency transducer in the frequency range 150-1500 Hz.
