Kloss then resumed work on increasing the fidelity of cassette tapes, a format that had originally been developed to be used only for voice dictation. They were usually offered in both wood veneer and vinyl-covered 'utility' cabinet versions, which other than appearance were acoustically identical. It rivaled the sound of the then top-line AR Model 3a (which used three drivers and a 12-inch (30 cm) woofer), but only cost about half as much.Īdvent produced a number of different versions of the 2-way Advent, including the Advent Loudspeaker, the Smaller Advent Loudspeaker, the 'New' Advent Loudspeaker, Advent/2, Advent/3, 4000 series, and 5000 series, to name a few. To earn some money, he decided to build a high-performance low-cost dual driver speaker system with 10-inch (25 cm) woofer called simply The Advent Loudspeaker (later given the retronym the Larger Advent, after introduction of The Smaller Advent Loudspeaker). Around 1968, Kloss quit KLH to develop a low-cost projection television, but had trouble financing the leading-edge research and development that was still required. The name came from the legal description the advent corporation used in the incorporation documents as a placeholder name before the actual name was selected. Later models also supported recording on tape.Īdvent Corporation was a consumer audio and video hardware company founded in Cambridge, Massachusetts by Henry Kloss in 1967.
