RadioShack Optimus Pro LX5 loudspeaker
It was a classic American tale: hearing that the head honcho of RadioShack was in town, the principals of Oregon-based high-end loudspeaker manufacturer Linaeum found out where he was staying and called him to see if RadioShack would be interested in marketing their speakers. They were rewarded for their daring by being given an introduction to the right RadioShack department head, and before you could say time-coherent, a deal was struck for RadioShack to manufacture a new line of three "audiophile" loudspeakers featuring a version of the unique Linaeum tweeter. The less-expensive Optimus Pro X77 and LX4 models use a baffle-mounted tweeter that radiates just to the front; the top-of-the-line Optimus Pro LX5 reviewed here mounts a bi-directional tweeter on the top of a diecast aluminum enclosure.
