Rectilinear Research Corporation was a manufacturer of loudspeakers. The company was formed around 1966 and its principal was Morris I. Wiener of Plandome Manor, New York. The first known main office location for the company was at , Brooklyn, New York. Some time around 1968, the company moved headquarters, manufacturing assembly, and service center to in the Bronx. The company remained at this address until it was shuttered in 1977-8. Arnold Schwartz, James Bongiorno, Marty Gersten, Jon Dahlquist, and Richard Shahinian were at different times and at different stages working with the company as engineers to develop speaker models. The company launched its first model, the Rectilinear III, in 1966. The early versions were designed by Arnold Schwartz and later by James Bongiorno. The first known independent notice for the "III" is a retailer advertisement dated 12/4/1966. This model, as did many later Rectilinear models, received many positive reviews by audio journalists in major audio magazines, including Stereo Review, Popular Electronics, Buyer's Guide Magazine, and Stereo & Hi-Fi Times. Three of the company's print advertisements were illustrated by the artistRick Meyerowitz and ran in publications such as Rolling Stone, National Lampoon, and others in 1973 and 1974. Although formally this model always carried the name "III", it was colloquially often nicknamed the "Highboy" following the launch of the "III Lowboy" in order not to confuse the two models. Both the III "Highboy" and III Lowboy are pictured here. By 1971, Rectilinear had expanded its product range to include the following speaker models :
Some of these early 3-way models featured 10" and 12" woofers manufactured by Jensen and CTS, 5" whizzer conesquawkers manufactured by Philips Electronics of the Netherlands, and 2" and 2.5" cone tweeters by Peerless of Denmark. The Rectilinear speakers were typically, but not always, of porteddesign and finished in walnut with fabric or fretwork grilles. Many models featured one, or sometimes two, rear tone controls. The company offered some of their models as kits and "semi-kits". Later models include:

The company also produced a tilted speaker stand, the "Rectilinear Dispersion Base", intended to be used with the Model 5 speaker. Although the Rectilinear speakers were distributed through a nationwide network of up to 400 dealers, most of their sales was generated on the East Coast. Distributor in Canada was H Roy Gray Ltd., 14 Laidlaw Blvd., Markham, Ontario. International and military sales were offered by Royal Sound Co., 409North MainSt., Freeport, New York.
