The Outline P4 packs professional coaxial performance into an ultra-compact, IP54-rated design. With true point-source architecture and 117 dBZpk output, this Italian-engineered speaker delivers exceptional clarity for installations where space is limited but sound quality cannot be compromised. Ideal for distributed audio, corporate AV and background music applications across Australia.

The Outline P4 is a compact coaxial loudspeaker that brings high-end Italian point-source performance to installations where every millimetre counts. Designed for situations that demand clarity without drawing attention to the hardware, this passive 2-way system excels in corporate boardrooms, retail spaces, hospitality venues and protected outdoor areas across Australia.

At its heart is a true coaxial driver pairing a 4" woofer with an integrated 1" high-frequency diaphragm. This configuration produces a perfectly aligned 80° conical coverage pattern that remains consistent across the listening area, eliminating the off-axis inconsistencies common in conventional speakers. Whether mounted on walls, tucked into ceilings or flown discreetly, the P4 delivers even, natural sound from 110 Hz right up to 21 kHz.

Built to survive real-world conditions, the cabinet is formed from injection-moulded high-modulus polyurethane with internal 3D structural grading that enhances rigidity and acoustic performance. An IP54 weather-resistance rating means it can be confidently used in covered outdoor environments, while the ultra-thin proprietary off-black coating provides a discreet, professional appearance that blends into any venue aesthetic.

Installation is made simple with selectable pin assignment logic on the wiring, allowing system integrators to adapt quickly to different amplifier configurations without custom cables. The robust weave-patterned steel grille protects the drivers while the rotatable Outline logo ensures the branding always faces the right way, regardless of orientation. At just 158 x 133 x 112.5 mm and a lightweight 1.9 kg, the P4 can be mounted almost anywhere with minimal visual impact.

With a maximum output of 117 dBZpk, the P4 proves that serious performance can come in a very small package. It is the perfect choice for background music, corporate AV, distributed audio and any application where premium sound, reliable weather resistance and unobtrusive size are essential.
