Sony SS-X300 (1990s)
A two-way bass reflex loudspeaker with a 25 cm mica-reinforced polypropylene woofer and soft dome tweeter.
Overview
The Sony SS-X300 is a floor-standing loudspeaker from the 1990s, designed for high-fidelity audio reproduction. It features a 2-way bass reflex configuration with a 25 cm woofer and 5 cm tweeter, delivering a frequency response from 35 Hz to 20 kHz. A reviewer notes these speakers are "very well balanced" with "good bass extension" and "smooth highs," describing them as "very easy to listen to" despite not being the most detailed or transparent by modern standards. They are regarded as a well-engineered, musical design typical of Sony's late '80s to early '90s speaker engineering.
