The Model Five loudspeaker is designed around two guiding principles that perfect its sound quality. The first principle is the acoustic suspension design. Unlike bass-reflex systems, the acoustic suspension design is not optimized to favor one frequency band at the expense of another. The volume of the air in the enclosure ensures that the 10-inch woofer will always be in control, and the low-frequency performance will remain clean even at the highest cone excursions. Secondly, the dedicated midrange driver is specifically designed to reproduce the important, middle part of the audio spectrum- the area where the ear is the most sensitive and where distortion is most easily heard. This guarantees the output is clean and detailed at all levels.
