WARNING! The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and mainte-

nance (servicing) instructions in this manual.

•Before placing, installing, rigging, or suspending any speaker product, inspect all hardware, suspension, enclosures, 

transducers, brackets and associated equipment for damage. Any missing, corroded, deformed, or non-load rated com-

ponent could significantly reduce the strength of the installation or placement. Any such condition severely reduces 

the safety of the installation and should be immediately corrected. Use only hardware which is rated for the loading 

conditions of the installation and any possible short-term, unexpected overloading. Never exceed the rating of the 

hardware or equipment.

•Consult a licensed, Professional Engineer regarding physical equipment installation. All local, state and national reg-

ulations regarding the safety and operation of equipment are understood and adhered to.

•Use only load rated hardware to attach to the eyebolts or pull-back bar when suspending these products.

•Do not suspend these products from any structural element on the enclosure other than the load rated M10 suspension 

points.

•Do not suspend the HPR152i or HPR153i horizontally under any circumstances using this or any other hardware.
