User manual TANNOY PRECISION DESCRIPTION

[. . . ] Taking full advantage of significant advances in digital speaker measuring techniques such as KlippellTM symmetry and nonlinear distortion analysis, laser scanning interferometry, acoustic CAD simulation and our own cutting edge acoustic technologies, Tannoy engineers have developed two new active monitors. The new Precision D range incorporates the latest Tannoy Dual ConcentricTM driver and WideBandTM Technology to deliver near field monitoring speaker designs that set new standards of acoustic performance and accuracy. [. . . ] The crucial benefit at the mix position is the delivery of a more natural and cleaner sound with greatly enhanced intelligibility. Characteristic of the Dual design is a very wide 'sweet spot' with an exceptionally even response throughout the listening area and extraordinary transient response. This phase accurate Tannoy designed drive unit has, for all these reasons, been the choice of professional studio engineers for decades. Tannoy has been at the forefront of developing loudspeakers with WideBandTM performance. Extending the high frequency roll-off out to 51kHz corrects the time or phase response at the upper end of audibility, resulting in enhanced accuracy and `air', improved clarity within the essential mid band area, and even enhancing definition of low frequencies. Tannoy WideBandTM Technology is an essential component of the Precision monitor design delivering increased tonal accuracy of the individual instruments in the recording process - a mix-critical factor allowing the best EQ and placement decisions to be made. Tannoy engineers have researched ways of dealing effectively with the acoustic effects of mid, near and close field listening distances, in order to compensate for the relative size and distance of the acoustic source and resultant spherical / plane wave dilemmas. Additionally, the effect of boundaries near a monitor speaker, such as walls, support tables and mixing console surfaces can change the air load on the low frequency cone piston and consequently the radiating efficiency in the 100Hz to 800Hz region. A set of DIP switches on the rear control panel of the new Precision D active monitors allow the selection of an optimum speaker response for real life and often difficult monitoring situations so that the frequency response at the listener's ears is always as linear and flat as possible. Optimisation can be preset for far field (>2m), mid field (1~2m), near field (~1m) and close field (<0. 5m) situations in combination with free space (4pi), half space (2pi), quarter space (pi) and extreme eighth space (pi/2) corner situations. Precision D Active monitors can therefore be optimised for varying listening distances in difficult acoustic spaces; varying meter bridge positions, against and adjacent to walls or reflecting surfaces, in corners, in corners on shelves or brackets, table top / space restricted PC/Mac based sound editing environments and stand mounted or soffit mounted configurations.
