1 Aligning Cabinets with
DuoTilt™
The novel integrated DuoTilt™ pole mount allows
sound energy to be utilized far more efficiently.
With two angles of tilt to choose from, 3° and 7°, the
enclosure can be aimed directly at the audience.
The cabinet is stabilized at its center of gravity – no
wobbling, unwanted tilting, or unintentional turning.
Your choice of DuoTilt™ angle – 3° or 7° – depends
on the required speaker height and the size of the
room. If you set mid/high units on fully extended
tripods or mounting poles, select 7° to minimize
ceiling reflections.
If you want to address an audience where more
listeners are farther away from the speakers, use the
HK Audio® DuoTilt™ at the 3° angle.
Mono Tilt 3™ (PR:O 8 A) offers one angle of tilt.
