The IP8-1153 is a high power, 15-inch, three-way, point source loudspeaker. The rotatable 18-inch (457mm) MF/HF waveguide provides well-defined coverage and a smooth off-axis response that enhances arrayability. The acoustically resultant 8th order MF/HF passive crossover produces a smooth, consistent vertical off-axis response free from the polar lobing and power response losses inherent in other similar systems. User selectable biamp or triamp operating modes expand performance capabilities further. FEA-optimized linear suspensions, high-flux neodymium motors, and integral demodulation rings ensure precise control and very low distortion at high SPL levels. The custom long-excursion LF driver delivers deep bass response and a balanced midrange in the most demanding applications. The matched diaphragms on the HF and MF compression drivers provide natural, transparent sound quality with unrivaled intelligibility and transient response accuracy that complements any source. I SERIES Point Source 800 loudspeakers provide exemplary acoustic performance, modular flexibility and elegant aesthetics for modern performance venues. Designed to support the goals of systems integrators and consultants both acoustically and mechanically, I SERIES includes a wide variety of arrayable, rotatable coverage patterns and a comprehensive selection of modular bracket systems that accelerate system design and system commissioning.
