What is stereo?

There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Tannoy System 8 NFM II

 The integration of all the features described HERE is what makes the whole loudspekaer system even greater than sum of the individual parts.
  • The style of the cabinet is not arbitrary, it has been arrived at by considering the acoustic principles of diffraction and energy storage.
  • The trim rings around the rubber surrounds are there to smooth out the otherwise discontinuous contour to the HF wavefront.
  • The smooth lines around the port tubes ensure laminar air flow at low frequencies where the air in the ports has maximum velocity.
  • The shapes of the LF cones contiune the hyperbolic waveguide for the HF energy propagation.
  • The cabinet bracing and internal construction ensures that the HF unit can deliver the detail into the sound field.
  • The application of the Differential Material Technology approach to component behaviour under vibration and magnetic fields has lead to custom crossover components, custom cabling and a split crossover design being employed.
 The result of all these innovations is a family of monitoring loudspeakers from Tannoy; speaker which are quite remarkable in resolving the finest detail over the whole audio spectrum.
The new Monitor Series loudspeakers prove that Tannoy still leads the world in applying the science of loudspeaker design to the practical monitoring situation. These monitors are tools to be used in producing even more artistic and satisfying developments within the live and recorded sound stage.
