Rudy T. Bozak (1910–1983) was a hi-fi pioneer famous for his loudspeaker designs.

"Ever since its introduction in 1951, this magnificent 14-speaker system has remained unmatched for its ability to accurately re-create any sound or combinations of sounds across the entire music spec­ trum. The Concert Grand is the supreme achievement in the faithful re-creation of sound. Each system contains 4 8-ohm B-199A bass speakers, 2 16-ohm B-209B midrange speakers, 4 B-200Y treble pairs, and an N-104 cross­over network installed in a rigidly constructed, heavily damped 16 cubic foot infinite baffle. The speaker panel and front half of the sides, top and bottom of the cabinet are 1 ½“ thick for extra rigidity. The midrange speakers are completely isolated from the woofer compartment."

The Model B-410, which has its treble array at the side, is furnished in mirror-image pairs with left and right hand versions to assure balance and afford a maximum of flexibility in stereo system setup.
