The LFC-210im is the first subwoofer model to appear in the “invisible mount” (im) series of products from Pro Audio Technology. Like all im models, the LFC-210im can be mounted within a standard 2" x 4" architectural wall and can be finished with an optional low-profile, minimum-frame, perforated grille to completely disappear into the home environment. The LFC-210im, at last, brings trademark PRO visceral-yet-tuneful subwoofer performance to the in-wall format. Unlike in-wall sub designs from other manufacturers, the LFC-210im is a true bass-reflex design allowing it to move more air, with greater efficiency and lower distortion. The result is powerful low frequency performance usually only possible from bulky, large format subwoofers. At the heart of the LFC-210im lie two long-throw, carbon-fiber 10" woofers with equivalent radiating area of a single 14" woofer. Four total high-power voice coils (two per driver) insure high power handling and high efficiency. Combined with the precisely tuned bass-reflex enclosure, these drivers provide low frequency performance of startling quantity and quality. With a maximum output of 114dB (in wall) the LFC-210im can be used as a primary or auxiliary subwoofer in a dedicated theater system, or as a (sub)woofer in high-output distributed audio applications.
