We continue to roam the Alexis Park complex, our antennae tuned for innovative home theater products. Among the most interesting: Legacy Audio's "Harmony" loudspeaker, perhaps the first truly high-performance in-wall we've ever heard. This unique design features a rigid back plate that's screwed into place in a sheetrock cutout between two studs on standard 16" centers. The fully assembled front baffle then slides into place and is secured by two screws. Unlike other in-wall designs that attempt to disappear, the Harmony actually protrudes about two inches from the surface of the wall. Its craftsmanship matched its sonic appeal—it was surprisingly deep and dynamic, but very natural sounding through the midrange and highs.
