Bose Spatial Control Receiver And Bose 10.2 Speakers

One the cleanest bose receivers out there 100watts per channel , and to pair with a bose 10.2 speakers the receiver comes with original Documentation from bose and original shipping box .clean superb sound for the old school sound You looking for The Bose 10.2 “Stereo Everywhere” speaker system is a direct descendant of the company’s earlier Direct/Reflecting speakers. Unlike conventional forward-radiating speakers, whose full stereo properties are usually audible only in a restricted portion of the listening room (typically along a line midway between the two speakers), the 10.2 has specific directional and frequency-response properties designed to generate an exceptionally strong, three-dimensional stereo sound image throughout the listening area. To achieve such a sound image, Bose uses a controlled dispersion pattern in which the signal radiated at a 45-degree angle into the room is 5 to 10 dB louder than in other directions. The 10.2 speaker has four drivers. Two 10-inch woofers are mounted 90 degrees apart on the speaker’s front and inward sides near the top of the columnar cabinet, about 33 inches from the floor. The combined radiation pattern of these drivers slants 45 degrees inward in the frequency range of 600 to 1,200 Hz. Two 3-inch cone tweeters', angled respectively 45 degrees inward and outward from the forward axis of the system, are mounted in front of the forward-facing woofer. The tweeters operate out of phase with each other, the inward-facing unit being in phase with the woofer behind it, which tilts the speaker’s overall radiation pattern 45 degrees inward (toward the in-phase tweeter) in the frequency range of 1,200 to 2,500 Hz, where both the woofers and the tweeters contribute to the total sound output. From 2,500 to 5,000 Hz, the tweeters alone operate, and their opposite-phased cones produce a figure-eight pattern favoring the inside and outside, with a forward null. Above 5,000 Hz, the outward-facing tweeter is shut off by the crossover network, leaving the natural directivity of the inward driver to beam its energy along its own 45-degree axis.
