AR 18 (c. 1978)

Little is documented about the AR 18. Almost everything the record shows comes from a single period advertisement. The AR 18 was a compact bookshelf speaker, called "the little fellow" in that ad, and positioned as the entry-level companion to the flagship AR 9. High Fidelity (October 1978, p.115) ran the ad, which used a Mutt and Jeff comic-strip motif to contrast the two models: the 18 at about $70 and the 9 at roughly $750. That price suggests the 18 was aimed at the budget-minded buyer, with an AR badge and presumably AR's design philosophy in a small, affordable package.

Beyond its existence and approximate price, no specifications have been located. That means no driver sizes, cabinet volume, frequency response, sensitivity or crossover details. No service manual, brochure or owner's manual has surfaced in the materials reviewed. The 18 does not appear in AR's typical product-family listings from the period, and no production run, introduction date or discontinuation year is recorded. It may have been a short-lived model or a regional release.
