The Precision 8D gets much of its clarity from a cast chassis Tannoy Dual Concentric driver. It's really two drivers properly merged into one, with the high-frequency mounted on the back of the low-frequency unit so that both drivers are on the same axis. As a result sound energy is propagated from the same point and delivered through the center of the low-frequency cone, providing a true point source. The Precision 8D's integrated approach provides a constant time delay over the frequency spectrum, offering better transient performance and sound quality with better harmonic alignment. The crucial benefit at the mix position is the delivery of a more natural and cleaner sound with greatly enhanced intelligibility. Another key benefit of the Precision 8D's dual design is a very wide "sweet spot" with an exceptionally even response throughout the listening area and extraordinary transient response.
