Under Pressure: Loudspeakers at Altitude
"The large peak at 16kHz reported by <I>Stereophile</I>...was nowhere in evidence...The most probable explanation of this discrepancy is that the [Waveform supertweeter's] very light ribbon depends on the air load for damping, and that load is much smaller in the thin air up there at 7000' in Santa Fe than at altitudes where less lightheaded and scientifically more accountable reviewers dwell." Thus spake Peter Aczel (footnote 1), erstwhile loudspeaker designer and Editor/Publisher of the reincarnated <I>The Audio Critic</I>, a publication that advertises itself as having "unusual credibility among the top professionals in audio."
