The Selenium 15PW6 15" PA woofer brings 400 watts RMS power handling and a solid bass punch to professional sound reinforcement system applications. A lightweight long fibre pulp cone and newly designed impregnated fabric surround ensure the speaker's moving parts assembly is controlled and resilient. Tonal quality is tight, articulate, and low in distortion, particularly in the bass and lower midrange frequencies. The 15PW6's high-temp copper wire voice coil is wound on a durable polyimide former, guaranteeing maximum heat resistance and excellent mechanical strength. A reinforced and epoxy coated stamped steel frame withstands harsh handling and tough environments. The hefty 24.9kg ceramic ferrite magnet provides high motor strength, assisted by Finite Element Analysis (FEA) optimization.
