Rudy Bozak was not in favor of using ports or vents to tune loudspeaker enclosures for greater low-frequency output from a smaller box. He was a purist; he felt that the impulse and transient response of ported designs was inferior and that the augmented bass was too boomy. By the late 1970s, this stance was considered old fashioned; the greater majority of home and professional loudspeakers were using ported designs. As the first ported loudspeaker model was being prototyped at his former company, Rudy Bozak remained skeptical but was willing to stand back and observe the results achieved using the new scientific design methods.
