Acoustic Research TSW 510 (late 1980s)
The TSW 510 is a three-way, sealed (acoustic suspension) tower speaker that appears to date from the late 1980s. Documentation is thin. No original catalog pages, retail price, or detailed engineering specs have surfaced, but enough listings and owner accounts exist to sketch a reasonable picture.
The known driver complement is a 10-inch woofer, a 6.5-inch midrange, and a ¾-inch titanium dome liquid-cooled tweeter with an acoustic lens. One Korean-language seller calls the woofer 12 inches. That conflicts with the more commonly cited 10-inch figure, and since most sources list 10 inches, that is the spec noted here. One listing describes the cabinet as solid wood construction, and a Korean owner says the model sits second in the TSW series.
A Craigslist seller who had the foam surrounds replaced on both the woofer and midrange drivers reported the speakers "work perfect at all volumes" and are "very efficient and light the room up," handling up to 150 watts. Another seller of new old stock asked $600, while used examples have appeared around $199. Foam surround deterioration is clearly the common failure point. Replacement kits and professionally refoamed examples are widely available, and one replacement tweeter diaphragm listing confirms the ¾-inch dome size.
Little else is known about the TSW 510. No frequency response, impedance, sensitivity, or crossover figures are documented anywhere in the sources reviewed. The "British-made" claim from one Korean listing is likely wrong, since Acoustic Research was historically an American company, and should be treated with skepticism.
