The new IDR™ (Improved Dispersion Recess) technology and an aluminum faceplate with a new refined texture offers extraordinary acoustical characteristics and exceptional quality finish. Small faceplate allows very close placement to woofer or midrange for improved sound integration. Fully shielded for A/V use.
