3 Acoustimass ¨ 10 Bass Module Description (Refer to Figure 1) Left woofer Reproduces all left channel low frequency information. This woofer is loaded by the Acoustimass 10 enclosure in such a way as to produce deep bass energy. Right woofer Reproduces all right channel low frequency information. This woofer is loaded by the Acoustimass 10 enclosure in such a way as to produce deep bass energy. Surround woofer Reproduces all left and right surround channel low frequency information. This woofer uses a dual voice coil that electromagnetically sums the left and right surround channel bass energy. The woofer cone then reproduces the summed left and right surround channel and sends it into the energy summing chamber (acoustic spring C). Acoustic Spring A This is the volume of air in the rear chamber (in front of the left and right channel woofers). This volume of air acts like a spring and acoustically couples the fronts of the left and right woofers to acoustic mass A. Acoustic Mass A This is the longer of the two internal ports and, together with Acoustic spring A, serves to reproduce the lower frequencies of the bass module, while reducing the cone excursion of the left and right woofers over this lower frequency range (35Hz to 60Hz). Acoustic Spring B This is the volume of air in the middle chamber (behind the left and right channel woofers). This volume of air acts like a spring and acoustically couples the rear of the left and right woofers to acoustic mass B. Acoustic Mass B This is the shorter of the two internal ports and, together with Acoustic spring B, serves to reproduce the upper frequencies of the bass module, while reducing the cone excursion of the left and right woofers over this upper frequency range (120Hz to 200Hz). Acoustic Spring C (The Energy Summing Chamber) This is the front most volume of air inside the AM-10 bass module. This is where the bass is summed. Within this chamber, the front channel bass energy is received via acoustic mass A and B, the surround channel bass energy is received directly from the surround woofer.
