INTRODUCTION

Niles once again raises the bar. With our first OS Indoor/Outdoor models we revealed a radical new understanding of loudspeaker capabilities. Niles original OS Indoor/Outdoor loudspeakers are constantly praised for their ability to deliver exemplary reliability and outstanding sound quality. These attributes have made Niles OS Indoor/Outdoor loudspeakers the best selling loudspeakers in their class.

The goal of our new OS Indoor/Outdoor line-up is to raise this bar with refined appearance and superior sonic performance. Once again establishing a benchmark by which all others are judged. 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 our integrated approach to driver and cabinet design. By integrating the woofer basket into the baffle of the cabinet we are 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 isn’t 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. After the installation is complete, you will be astonished by the experience of hearing such clean and powerful sound coming from such an elegant appearing loudspeaker.
