Lumina III fits a three-way system into a cabinet only nine inches wide. A dedicated 6-inch midrange handles voices, while two 6-inch woofers add enough area for solid bass to 40 Hz.
Reviews have praised its smooth balance, useful dynamics, and ability to work with many kinds of music. It is the Lumina floorstander for a medium room when a narrow footprint and easy placement matter more than the deeper bass and greater weight of Lumina V.
