Aiwa SX-R275
Little is documented about the Aiwa SX-R275 beyond its service paperwork and scattered resale listings. What the record shows is a small satellite loudspeaker - a 1-way, single-driver design built around a 2-inch driver, with an 8-ohm impedance and a 40-watt rating (quoted variously as RMS and music power depending on the listing). It was a surround satellite in a 5.1 setup, and it was sold alongside at least one matching sibling, the SX-R276. A center channel from the same family, the SX-C605, also appears in period bundles. The speaker is passive. One user report notes the SX-R275/R276 pair produces no output unless fed from a TV or external amplifier, which is what you'd expect from a satellite with no onboard electronics.
The strongest documentation is a 22-page Aiwa service manual filed under the Home Cinema category. It confirms the model designation and that Aiwa treated the speaker as a surround component rather than a standalone product. Sears PartsDirect lists it under "compact disc stereo system" parts, and the manual's connection notes warn to power down before wiring and to be careful mounting so as not to spoil the finish. That's about the extent of the technical record. No dimensions, weight, sensitivity, crossover frequency, cabinet material, or original retail price survive in the sources we can verify. Production years are likewise unrecorded. One aggregator page claims the SX-R275 includes a remote control and an iOS/Android app for EQ and volume. That claim is almost certainly wrong for a passive satellite and should be disregarded.
On the secondary market these turn up cheaply and often as new old stock, including factory-sealed pairs. Recent prices run from roughly $11 to $40, with a Greek listing showing a new pair at €23 and a Pakistani listing bundling a pair with a 2.1 system at Rs 11,000. They're not collectible in any serious sense.
