Among the top group of three closely ranked finalists in this test, the CDT HD-62ST wins the gold because, when mounted in the doors, it simply sounded the best. It combined the superb octave-to-octave balance of the Altecs with the magnificent transparency and resolution of the Boston's and the Polk's.
When describing the sound of the HD-62ST system, everything I say is actually about the beauty of the recordings --a golden tenor voice singing Handel, the seductively intimate sound of Jennifer Warnes and her (clearly audible) backup singers, the rich tone of a saxophone, the very different textures of a bass fiddle alternately bowed and plucked, the variety of instrumental tones in a symphony orchestra or a well-played synthesizer, the crisp impact of percussion, and the startling power of a trumpet call.
The trouble with speakers like the HD-62ST system is that their wonderful sound makes me late for appointments; when I arrive at my destination, I don't want to get out of my car.
