Advent OLA Original Large

The Original Large Advent (OLA) is a true 1970s hi‑fi legend—Henry Kloss’ iconic acoustic‑suspension design that delivered big, room‑filling sound from a deceptively simple, walnut‑veneered box. Introduced in 1969 as “The Advent Loudspeaker,” it featured the famous Masonite‑ring 10" woofer and the classic orange “fried‑egg” tweeter, a combo that gave these speakers their warm, full, and surprisingly powerful voice. Whether stacked in pairs or enjoyed solo, the OLA became one of the most beloved and best‑selling vintage speakers ever, prized for its smooth balance, deep bass, and no‑nonsense engineering.
