Something strange with the sound excursion funnel

#1 · June 10, 2011, 2:20 pm

Hello! There is a problem - when entering into beam excursion funnel, sound jammed. And it starts some kind of crack or something like that. This occurs specifically in one place (and I've speculation that it's somehow connected with the angle of inclination excursion funnel). Maybe someone has encountered the same problem?
