Sony SS-X1A Speaker System

A compact, magnetically shielded bookshelf speaker system designed for use with Sony Trinitron televisions and stereo systems.

Overview

The Sony SS-X1A is a compact 2-way speaker system for TVs and stereo setups, particularly Sony's Trinitron television models. It was sold as an optional accessory for the Sony Profeel KX-1901 and KX-2501 television sets. It's small, but the sound is good enough for small rooms. The system uses an air suspension design and is magnetically shielded, so it can sit near a CRT display without causing interference.

Design

The enclosure uses air suspension to get more bass out of a compact cabinet. The speakers are magnetically shielded so they can be used safely near CRT televisions like Sony's Trinitron models.

Context

Sony positioned the SS-X1A as an optional audio upgrade for two specific television sets, the Profeel KX-1901 and KX-2501. It was meant to go with the picture quality of Trinitron TVs and give them better sound in a space-saving package.

Market

The SS-X1A was listed at ¥8,500 per unit around 1983. Some sellers now consider it rare. A recent listing on Etsy offered a pair for $149.99 (with 20% off), described as in good condition, tested, and working well, with minor cosmetic marks.
