Somewhat of a revolution in low frequency audio - Acoustic Research's 1-W of 1954. AR got a Patent on their acoustic suspension design and their 1-W was advertised to have a frequency response down to 32 cycles per second with very low distortion unlike the stove sized loudspeakers of the day. Question; how many of these were produced and how long did they stay in production ?

Doesn't say when production actually began, Acoustic Research was founded in 1952 and incorporated in '54. The AR-1 was patented in '56. Looks like a couple thousand were sold that year. In '57 the AR-2 came out for less than half the price and sales rocketed to $1,000,000. The AR-3 arrived a year later in '58 and was sold for at least 10 years.

Fisher was another company quick to use the acoustic suspension principle and dome tweeters.

Allied was still selling the AR-1 in 1963, alongside the newer -2 and -3 models. It was absent in Allied's '69 catalog, by then offering several variants of the AR-2, -3 and -4.

I wrote the article below years ago, but never found out total production figures on the AR-1 or how long hey stayed on the market. I'm more of a KLH collector & have some early examples from 1957-8.

Thanks, I enjoyed reading that.

http://www.classicspeakerpages.net/IP.Board/ has an AR and a KLF sub-forum. Read quite a bit about the older AR loudspeakers there.

The AR-1W was in the line from 1955-1961.
