"My studies have shown that compression drivers have no perceivable nonlinear distortions at any level - even 124 dB."Does this include behaviour under power at relatively low frequencies? You cross a 1" exit driver at around 900Hz-1kHz which is considdered very low in pro-sound circles. How does the loading of an OS compare to say an exponential (or others) for high-SPL use (assuming same mouth area)?
