I bought my first trio of Mirage speakers (L/C/R–bought something cheaper for the surrounds) 23 years ago and have bought or recommended Mirage several more times since then. My current home theater uses Mirage Nanosat Prestiges.
Of the models for sale here, the only ones I’ve played with personally are the OMD-5’s, which I helped a friend pick out for all 5 channels of his home theater a few years ago, and the QPR (quality:price ratio) is sky high on those things. The omni tweeter design really does give them a more expansive sound than most conventional bookshelf speakers, and the overall sound quality matches or exceeds many speakers costing 3-4x the price offered here. I would have bought OMD-5s for my own home theater instead of the Nanosats if I only had the space.
Since Mirage’s acquisition by Audiovox, they seem to be disappearing from the mid-fi retail channels and showing up mainly on deal sites like this. My guess is that they’ll eventually discontinue the line altogether, so get 'em while you can.
