The new Niles OS Indoor/Outdoor loudspeakers owe much of their performance and sound quality advantage to design elements pioneered in the award-winning Niles DS Directed Soundfield loudspeakers. Their engineering advances come from Niles" integrated approach to driver and cabinet design. By integrating the woofer basket into the baffle of the cabinet they have been able to increase the woofer cone-area to cabinet-width ratio. Thus enabling OS Indoor/Outdoor loudspeakers to provide levels of bass performance that substantially exceed their physical size. However, deeper and more powerful bass isnât the only refinement in the new OS Indoor/Outdoor line-up. A new and modern style enables OS Indoor/Outdoor loudspeakers to blend seamlessly with the architectural elements both indoors and out. You"ll be astonished by the experience of hearing such clean and powerful sound coming from such elegant appearing loudspeakers.
