installation fl exibility
For installation fl exibility, the new HSi 430 and HSi 435
loudspeakers are designed for use either in simple pairs for
stereo use or in multiples for larger areas. Their “metal can”
backs make them ideal for ceiling installations, with a variety of
easy install features for existing ceilings. Additionally, for new
construction installations, the HSi speakers off er an optional
new construction bracket, the NCBR3, that acts as a perfect
guide when cutting the ceiling/wallboard.
