Technics - SB-302 Speaker set

Technics SB-302 vintage 3-way monitor speakers, produced during the absolute golden age of Japanese hi-fi (circa 1974–1976) by Matsushita Electric. Technically in 100% good working condition and visually in nice vintage condition with light signs of use consistent with age.

For true vintage audio and design enthusiasts, the SB-302 is a particularly interesting piece of 1970s technology. What immediately stands out is the iconic acoustic lens (diffuser) for the tweeter. This high-quality design element – at the time mainly used on the heaviest high-end studio monitors – provides an unprecedented wide and even horizontal dispersion of the high frequencies. As a result, the stereo image is set large and the sweet spot in the listening room is greatly widened.

Aesthetically the speaker exudes pure mid-century craftsmanship: a heavy, wood-finished enclosure that beautifully contrasts with the dark, matte-black baffle and the recognizable light-colored, ribbed woofer cone. The ribbed structure (corrugated cone) is not merely cosmetic; it is a technical solution to counteract resonances and distortion (cone break-up) in the diaphragm. Because the SB-302 is designed as a closed system (acoustic suspension), the impressive 250 mm woofer delivers an extremely tight, fast, and controlled bass fundament without any wooliness. The dedicated 120 mm midrange driver ensures that vocals and instruments distinctly come forward from the bass. Through the continuously adjustable attenuator on the front panel, the high end can be seamlessly tuned to the room’s acoustics. A relatively rare, very musical speaker that makes a strong impression both sonically and in industrial design.
