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.

mbl Magnetostatic Super Tweeter


MBL Magnetostatic Super Tweeter
Over the 28 mm dome a new magnetostatic driver is used as a super tweeter. The decision to use this design is the result of some fundamental physical considerations. For the representation of frequencies exceeding 30 kHz in an authentic way only a ribbon tweeter, electrostatic or, as in this case, a magnetostatic transducer can be considered. Ribbons and electrostats have disadvantages compared to a genuine magnetostat. For example an electrostat requires a separate high voltage power supply to the transducer and has a smaller dynamic range as compared to a magnetostat. A ribbon tweeter does not offer the longterm stability and has a very narrow sound dispersion.

Only the magnetostat comprises all the advantages such as:
Extremely low mass, resulting in a perfect transient response.
High dynamics transparency and fidelity in detail
No partial oscillation
Good radiation characteristics
Linear frequency range up to over 50 kHz
Accustically neutral foil - no sonic signature
Constant impedance
Very high long-term stability
