Profile: Interfire Audio, Inc. is a manufacturer of audio electronic systems, and retails automotive sound equipment. Our product line includes amplifiers, subwoofers, speakers, mid range drivers, processors and other components. The IFH series amplifiers were designed for anyone looking for a real world, seriously performing amplifier. The ever powerful IFH series high current amplifiers have not changed much in the past five years, which is very rare, compared to a lot of other brands these days. These amps provide with the finest in audiophile quality sound. These crossover networks have been painstakingly designed to match the performance characteristics of the IFC series speakers. The results are crisp, clean highs, and transparent midrange, with no audible dips. With the IFC series components, there is beautiful music reproduction from 40 Hz to 25 kHz. All IF & IFC series component tweeters come with both angled surface and flush mount kits, giving plenty of installation possibilities to achieve near perfect imaging. These IFC series component midrange speakers feature heavy gauge polypropylene cones along with soft dust caps. While the thick injected polypropylene cone produces excellent low midrange frequencies, the soft dome dust cap naturally produces the upper midrange frequencies. The result is a smooth, natural, linear sound production.
