Influential early analysis found truncated line sources have little to recommend them

Evidence

Lipshitz and Vanderkooy (1986) provide a thorough theoretical background to the behavior of “finite length” (not full height), truncated, line sources and they point out a number of problems, ultimately concluding that “there is little to recommend the use of line sources as acoustic radiators”. They did grant that full-height lines had potential if the −3 dB/octave tilt in the frequency response is corrected. — Toole, Floyd E, Sound reproduction- the acoustics and…, 1280
