Kloss as well while at Advent, he introduced the Advent Video Beam 1000, the first color big screen television for home use. While, in 1981, there were certainly more advanced machines on the market, the Advent 201 more than held its own in terms of sound quality. Some 10 years later, I became friends with a 201 owner. In 1971, he introduced the world's first cassette deck with Dolby noise reduction, the Advent 201. Kloss worked diligently in the pursuit of changing the compact cassette from a format suitable only for dictation, to a format capable of reproducing true high fidelity. I owned a pair of Large Advents while in my late teens, and I still remember them quite fondly.Īdditionally, while at Advent, Mr. They became the best selling loudspeakers of their time. He introduced two acoustic suspension speakers, in different sizes, aptly dubbed the Small Advent and Large Advent. There, as in previous endeavors, he experienced great success.

Also introduced was the Model 11, a portable phonograph that was the first product to use solid-state technology. Kloss became a co-founder of KLH, where he introduced the Model 8, a good sounding, high selectivity table radio. While acoustic suspension designs can reproduce deep bass, they tend to be less efficient than other designs, requiring more amplifier power. The popularity of acoustic suspension speakers led other manufacturers to make more powerful amplifiers. Before acoustic suspension speakers came to the forefront, high quality speakers tended to be quite large, to reproduce the lowest frequencies. Along with engineer Edgar Villchur, he used his talent for invention in the development of the AR Model 1, the first acoustic suspension bookshelf loudspeaker. He was 72.Īfter graduating from the Massachusetts Institute of Technology, he joined Acoustic Research in 1952.
