D900

About

The Tannoy D900 is a floorstanding loudspeaker that forms part of Tannoy's discontinued Definition series, which included models like the D100, D300, D500, D700, and the center-channel D750. It features a unique trapezoidal cabinet design that helps to minimize standing waves and provide optimal sound projection. The D900 utilizes a 3-way configuration with a pair of 12-inch polypropylene-coned drivers combined with a 1-inch horn-loaded metal-dome tweeter, which is mounted concentrically with the midrange driver, creating a cohesive soundstage. This model is known for its exceptional bass response, offering deeper low frequencies compared to its smaller counterparts, the D700 and D500, making it ideal for dynamic genres of music while also maintaining clarity in vocal performances. The claimed sensitivity of the D900 stands at approximately 93dB with a maximum SPL of 118dB, indicating its capacity to handle high levels of playback without distortion. The frequency response is stated at ± 3dB from 35Hz to 30kHz, showcasing its capability to reproduce a wide range of audio frequencies. The speaker is designed with an easy-to-drive nominal impedance of 6 ohms, but the load can dip as low as 3 ohms, which may require careful amplification matching. In practice, users have reported that the D900 provides a sound signature that remains consistent across various volume levels, delivering a rich and engaging listening experience that excels in both large orchestral pieces and more intimate musical settings.
