Using three-dimensional mapping technology developed by Lyngdorf, the Model D (incidentally, the designation for Steinway's flagship concert grand) is able to adapt to the acoustic characteristics of its environment for optimum audio performance. Each unit is installed and "voiced" by a Steinway Lyngdorf specialist. The unit's pair of "open-baffle" speakers, each over six-and-a-half-feet tall, contains solid blocks of aluminum to provide for uniform sound distribution without excess bass.
The Model D was first launched in May and has since been previewed in Los Angeles, San Francisco and Dallas. The Ritz hotel in Paris and the Core Club in New York City have made arrangements to acquire the system. Production for 2007 is set under 100.
