About the 821
The RBH Sound Premier 821 is a high-fidelity, high-output large bookshelf speaker designed for both 2-channel music systems and home theater use. RBH describes it as the bigger sibling to the Reference 621, using dual 8-inch black-anodized aluminum woofers and a large AMT tweeter to deliver extended low-frequency performance, detailed highs, and strong dynamic range. It is available in black or white satin finish and is sold per single speaker. The published product page does not list every electrical specification, but it emphasizes reference-level performance, high power handling, and use as a main or effect channel in larger surround systems.
