Bottom line: For the likely applications in which these speakers would be specified, they really shine. They’re not perfect, but they’re not expensive, and I would rate their bang-for-the-buck quite high. I would definitely specify these speakers for any of the types of installs touted by the manufacturer—restaurant, retail, corporate/industrial, theatrical, bar/hotel, and under-balcony fill.
