PUI Audio Enclosed Speaker Components are optimized drive units paired with ABS (UL94V-0) enclosures that offer sound quality and durability. Each model maximizes the SPL of the loudspeaker unit within its usable range. The variations offer 8Ω impedance, 500mW to 5W power rating, and sound pressure levels ranging from 79dB to 97dB. Each is equipped with 150mm wire lead (26AWG) attached for convenience in connectivity within any application. PUI Audio Enclosed Speaker Components utilize aluminum, mylar, or treated paper cone material with neodymium or rare Earth magnet material. These components are available in an oval, round, or square shape. Typical applications include medical, fire, safety, security, and industrial.
