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 311E speakers


This model is a 2½-way, 4  bookshelf speaker. In common with the mbl 300E, the cabinet utilizes a 170 mm Kevla cone - now as a woofer/midrange driver, a 28 mm soft dome tweeter and the magnetostatic super tweeter.
The sound "blooms" from the speaker, rich in nuances, with high resolution and a clear, structured bass.

Features:
Magnetostatic super tweeter, for ultra high frequency bandwidth features a 4 mm aluminum mounting plate with sound dispersion grooves
Super tweeter housed in a separate closed chamber to avoid air compression
Soft dome tweeter with excellent linearity ±0,5 dB
Midrange driver utilizes a lightweight stiff Kevlar membrane for fast pulse response
Newly developed crossovers made from top-class materials (air coils, metal-oxide resistors, etc.)
Crossover design for bi-wiring, bi-amping
Wiring with top-quality low oxygen single crystal OCC/OFC copper cables
Low-resonance 22 mm MDF cabinet
Unique exterior asymmetric panel face with curved edges-reduces edge defraction
Prefabricated cabinet base for mounting to MBL custom designed acoustically correct stands
