HK Audio Premium Pro 18 SA Active Subwoofer

Tired of toting heavy power amp racks and fussing with outboard controllers and crossovers? Do you want to travel light, carry less cargo, and set up your rig with a few effortless twists of the wrists? Then check out the active versions of the PREMIUM PR:O line.

This line's engine room is an ultra light power amp block featuring ultra efficient Class-D technology that delivers 600 watts yet remains phenomenally cool. Unbelievable but true, this cabinet weighs just a couple of pounds more than its passive cousins! Having all the power circuitry on board means more than mere convenience. Our engineers were able to select and match every component in the signal chain, and then fine-tune the circuitry to suit the speakers for best response and reliability. Every enclosure apart from the PR:O 12 MA and the two subwoofers features a fully adjustable Tone Control that adapts it to the given sound reinforcement demands. The PR:O 18 Sub A / PR:O 210 Sub A ships with a variable crossover.

Sporting an 18" woofer in a bass reflex housing, this bin builds a rock-solid bass foundation for every sound system. The specially designed crossover feeds the correct frequencies to the mid-/high-range unit connected via the Satellite Out. The active PR:O 18 Sub A model comes with 600 watts power circuitry and an active stereo crossover facilitating combinations with powered satellites.
