The multi-band PT Progressive Transition mid-high frequency waveguide provides well-controlled coverage and is rotatable for cabinet positioning in either horizontal or vertical orientation. High-slope crossovers minimize band overlap and well-controlled off-axis response enhances arrayability. The cabinet is fitted with M10 threaded suspension points. Pre-engineered array bracketry is available. AM7315 is part of JBL’s AE Application Engineered Series, a versatile family of loudspeakers for a wide variety of fixed installation applications.
