Sony APM-77 W

A bookshelf-type 3-way speaker system that's all APM, with performance comparable to floor-standing studio monitors. The flat and square woofer is driven by 4 independent voice coils with direct dual-surface drive for outstanding low frequency response and resolution.

Maximum power handling capacity of 200 W.

 The Sony APM-77 is the original "affordable" APM loudspeaker. It sported a stark grey finish and was thus quite futuristic. However, as the 1980s turned out to be far more conventional than expected, it is the later APM-77W (W for Wood) that is well remembered. Unfortunately, wood or not, the APM-77 didn't sell that well although it does provide a very balanced sound.

APM drivers are made of an aluminium honeycomb mainframe with ultra-thin aluminium covers - 100x more rigid than paper cones. The japanese magazine Audio Accessory often used Sony's APM loudspeakers for its reviews.
