Audiosphere Research were a brand that were low cost big box speakers. I sold them in the 70's you could buy a speaker like you have for the same price as a Dynaco A25 XL. The tweeters were usually piezo or CTS cones. The cost of components and construction were better than some brands, but far below others.
