2 150,00 €
Scansonic MB-Center B is a center speaker designed for the dialogue channel in an MB Series home cinema system. Its sealed ribbon tweeter and two 5.25-inch drivers cover the frequency region important for speech intelligibility. The curved, braced bass-reflex cabinet has adjustable aluminium feet that help level the 10.3 kg speaker securely. An amplifier rated at more than 50 W is recommended.
Scansonic MB-Center B is a center-channel loudspeaker featuring a sealed ribbon tweeter and two 5.25-inch bass/midrange drivers.
Role in a home cinema system
The center channel reproduces most film dialogue and much of the action taking place in the middle of the screen. This speaker is tuned with particular attention to the frequency range that is important for clear speech articulation. It is designed for use with other Scansonic MB Series speakers.
The MB-Center B uses the same bass/midrange driver section as the MB-2.5.
Driver design
The sealed ribbon tweeter has a diaphragm made from layers of Kapton and aluminium. The two 5.25-inch drivers use carbon cones. Their overhung magnetic system has a voice coil that is longer than the magnetic gap.
The internal crossover points are 250 Hz and 3.5 kHz. A first-order slope is applied at 250 Hz, while the tweeter is divided at 3.5 kHz with a second-order acoustic slope. These settings are part of the factory-designed crossover and are not controls that the user needs to adjust.
Cabinet and placement
The curved, heavily braced bass-reflex cabinet measures 480 mm wide and 178 mm high. Its 286 mm depth should be considered when selecting a shelf or television cabinet. The speaker weighs 10.3 kg, so it requires a stable supporting surface.
Adjustable aluminium feet help level the speaker on the chosen surface. Position it as close as practical to the horizontal center of the screen. If the height of the furniture permits, aim the tweeter towards the main listening position.
Connection and system setup
Connect the speaker by speaker cable to the center-channel output of an AV amplifier. Maintain matching polarity at both ends of the cable. Once connected, set the center-channel distance and level for the main listening position.
The stated impedance is greater than 4 Ω, but this figure does not define a separate nominal or minimum impedance. The store recommends a good-quality amplifier rated at more than 50 W. This is an amplifier recommendation, not a declared power-handling limit for the speaker.
The frequency range is given as 45 Hz to 40 kHz, but no dB tolerance or measurement conditions are specified. Set the AV amplifier’s bass-management crossover according to the complete speaker system, the room and the subwoofer being used.

FAQ
What is this center speaker designed for?
It is designed for the center soundtrack channel in an MB Series home cinema system. Its design gives priority to the frequency range that is important for dialogue.
How do I connect it to an AV amplifier?
Connect a speaker cable to the amplifier’s center-channel output. Observe the correct polarity, then calibrate the channel level and distance for your listening position.
Do I need to set 250 Hz and 3.5 kHz on the amplifier?
No. These are the speaker’s internal crossover points. The AV amplifier’s bass-management settings are configured separately according to the complete system.
Where should I place it?
Position it in line with the center of the screen, either above or below it. Allow enough space for the 286 mm cabinet depth and use a stable supporting surface.
Is more than 50 W a mandatory minimum?
No. It is an amplifier recommendation, not a specified minimum requirement or a power-handling limit for the speaker. Choose the final listening level according to the room and listening distance.
