Outline P4 2-Way 4″ Passive Coaxial Enclosure

The Outline P4 delivers professional point-source audio in an ultra-compact, weather-resistant package designed for demanding installation applications. Featuring authentic coaxial architecture with a 4″ woofer and integrated 1″ HF diaphragm, this IP54-rated speaker provides consistent 80° conical dispersion across its entire frequency range, ensuring precise directivity control and uniform coverage throughout the listening area. Built with injection-molded high-modulus polyurethane and incorporating structural internal 3D-grading, the cabinet is engineered for optimal acoustic performance in both indoor and protected outdoor environments. Additionally, the P4 includes selectable pin assignment logic that simplifies wiring in complex systems, while the weave-patterned pressed-steel front grille with rotatable logo shield combines robust protection with professional aesthetics. Despite its compact 158mm x 133mm x 112.5mm dimensions and lightweight 1.9 kg construction, the P4 delivers impressive acoustic output with 117 dBZpk maximum SPL and extended frequency response from 110 Hz to 21 kHz. Therefore, this Italian-engineered speaker is perfect for distributed audio systems, background music installations, and corporate AV applications where space is limited but professional sound quality cannot be compromised.
