Sony SS-9300 (c. 1970s)

A barrel-shaped, omnidirectional speaker system designed for full-room sound dispersion.

Overview

The Sony SS-9300 is a floor-standing speaker system from the mid-1970s. You can't miss it: the cabinet is a barrel, and the sound goes out in every direction. It has five 10 cm full-range cone drivers mounted radially, which gives a diffuse listening experience. The spherical cabinet construction is meant to minimize resonance and improve acoustic performance. It came in walnut and tamo finishes with an open-pore texture, and a dedicated cushion was included so the speaker could double as a seat. Sony positioned it slightly smaller than the SS-9500 in its speaker lineup.

Design

The SS-9300 uses a barrel-shaped (樽型) enclosure with spherical material processing to add mechanical strength and reduce unwanted resonance. The five full-range drivers are mounted radially and emit sound omnidirectionally. With the dedicated cushion in place, the unit works as a seat.
