?Products? This is a used product. KENWOOD LSF-777 Reference Speaker System Serial No. Rare This speaker system was developed as a reference speaker, embodying the point source concept. It is equipped with a 15cm cone woofer in the low frequency range and a 2.8cm soft dome tweeter in the high frequency range. The network section employs a SS (Subtraction Series) network, which uses a method in which the same current flows to the two units near the crossover frequency. The circuit configuration ensures that the total energy of the two units is always equal to the input energy to achieve an ideal crossover curve. The front baffle uses a DDD (Diffused Diffraction Design) baffle to prevent diffracted sound waves from adversely affecting sound quality. Diffraction is dispersed and reduced by minimizing the number of corners and by not making the distance from the unit to the corners equidistant. The enclosure is made of real wood and MDF, and a die-cast aluminum baffle is used to eliminate resonance. Gold-plated speaker terminals with banana plugs are used for the speaker terminals.
