DESCRIPTION
•Compactloudspeakerwithno compromisein soundquality
•Forportableuseor permanentinstallation
•100°conicalbeamwidth
•Passivecrossoverfor singleamplifier operation
The JF80z is an ultra compact loudspeaker, engineered for
exceptional, near-field performance. It provides surprisingly high
output and exceptional fidelity for foreground and background music
applications. It's speech projection capabilities also make it very
effective as a fill or delay element in larger audio systems. Unlike
many compact loudspeakers, the JF80z produces the high impact,
high definition sound projection expected in professional PA
applications. Its wide angle projection makes audience coverage
easy in a variety of situations. While the JF80z is well suited as is for
many applications, the addition of a subwoofer can expand its
capabilitiesformoredemanding applications.
Foam-backed grilles hide the drivers from view for pleasing
aesthetics.Top,bottomandsidemountingpointsallowenclosuresto

pole mounting, such as the K&M™ 195/8 or Ultimate Support™
BMB-200K.Standardcolorsareblackandwhite.Othercolorscanbe

The diverse applications for the JF80z include: band PA, multimedia
systems, retail spaces, presentation suites, shopping malls, smaller
houses of worship, theatres, auditoriums, lecture halls, and theme
parks.Fill/delayapplicationsinclude arenas,stadiums,concerthalls,
theatres,andhouses ofworship.
