The Outline P15 represents the pinnacle of point-source speaker design, combining Italian engineering excellence with professional-grade performance. At its heart lies a true coaxial configuration featuring a premium 15″ neodymium low-frequency driver with a 3″ voice coil paired with a 1.3″ exit neodymium high-frequency driver. Furthermore, this innovative design ensures optimal sound control with a precise 80° x 60° spread pattern. The system delivers clear sound across the entire frequency range of 45 Hz to 19.5 kHz. As a result, every audience member experiences consistent coverage. Moreover, the system produces impressive maximum output levels of 118.3 dBZ with peaks reaching 136.7 dBZpk. Built from certified baltic birch plywood, the cabinet features premium dovetail-joint construction reinforced with structural braces for maximum stiffness. Additionally, the enclosure is protected by high-grade polyurea coating in the proprietary Solar gris finish. The IP54 rating ensures reliable operation even in challenging environmental conditions. What’s more, the thoughtfully designed asymmetrical cabinet enables versatile deployment as either a main PA speaker or stage monitor, with monitor angles of 30° and 55° available. The weave-patterned pressed-steel front grille protects the drivers while maintaining acoustic clarity. Meanwhile, the rotatable “always-ortho” logo shield ensures professional appearance in any orientation. Engineered for professional touring applications, the P15 includes integrated rear-mounted handles for easy transport and positioning. In addition, multiple mounting points (6 x M8, 4 x M6) enable secure rigging in fixed installations or flown arrays. The dual Neutrik Speakon NL4 connectors in parallel simplify system wiring and ensure reliable connections. Weighing just 24.8 kg with compact dimensions of 674 x 463 x 390 mm, the P15 balances portability with robust construction perfectly. Therefore, whether deployed as a main PA system for corporate events or as stage monitors for live performances, the P15 delivers consistent, professional results every time.
