The Orian Bookshelf Speaker will deliver big and spacious sound with powerful output capability. The 5-1/4” coaxial midrange/tweeter uses an open back enclosure to produce an uncolored and natural response while taking advantage of reflections for a wide enveloping soundstage. The high excursion 8” woofers pump out room shaking bass with extension into the lowest octaves. This kit includes everything you need to build a pair of high-output bookshelf speakers, including: knock-down cabinets, drivers, crossover components, damping material, wire, and screws.
