HK PREM-PRO-15 800 Watt 15" Passive Speaker

With its 15" woofer, the HK Audio PR:O 15 offers the same clarity and projection as the PR:O 12 but with extended low-mid and bass performance, making it a strong candidate for standalone use—no subwoofer required. Its feedback-resistant tuning, solid SPL handling, and classic passive design make it a reliable workhorse for bands, DJs, and live sound installs.
