Scansonic MB2.5B Floorstanding Speaker
4 200,00 €
The Scansonic MB2.5B is a passive 2.5-way floorstanding speaker for a home stereo system with a separate amplifier. Two 5.25-inch carbon-cone drivers divide the reproduction of the midrange and bass frequencies between them, with the second driver providing support in the bass region. A sealed ribbon tweeter completes the three-driver configuration. The front bass-reflex port provides greater flexibility when choosing a position in the room.
The Scansonic MB2.5B speaker is a passive 2.5-way floorstanding speaker for a home stereo system. It is designed for use with a separate amplifier and is suitable for listeners seeking a speaker with a narrow cabinet. Two 5.25-inch carbon-cone drivers divide the reproduction of the midrange and bass frequencies between them. A sealed ribbon tweeter completes this three-driver configuration.
Driver configuration
In the 2.5-way design, one 5.25-inch driver reproduces both midrange and bass frequencies. A second bass driver of the same size provides additional support primarily in the lower-frequency region.
The ribbon tweeter uses a sealed design. The drivers are divided at crossover frequencies of 500 Hz and 2600 Hz. A minimum-phase crossover is used.
Cabinet and appearance
The substantial cabinet is curved, extensively braced and strengthened with carbon-fibre reinforcements. Rounded edges reduce diffraction and the cabinet’s influence on the frequency response. Viewed from the front, the speaker has an angular appearance, while its curved cabinet lines become more prominent from the side.
The restrained Nordic styling is available in three specified finishes: Black Silk, White Silk and Walnut.
Connections and amplifier selection
This is a passive speaker, so it requires an external amplifier and speaker cable. Its stated impedance is greater than 6 ohms. We recommend a quality amplifier rated at more than 50 W. This is a recommendation, not a confirmed minimum power requirement.
Consider amplifier power together with your preferred listening volume and the size of the room. Power figures should also be compared under equivalent measurement conditions. No such conditions are provided for this model’s amplifier recommendation.
Positioning in the room
The front bass-reflex port makes placement more flexible than a port located at the rear of the cabinet. Even so, the distance from the wall can affect the amount of bass. Begin with the speakers positioned farther into the room, then adjust their placement while listening to a familiar recording.
Adjustable aluminium feet help you level each speaker on the floor. Make sure the cabinet is stable and keep both speakers at a similar distance from the listening position. Turning them slightly towards the listener can alter the treble balance and stereo image.
The 178 mm width helps conserve floor space, although the cabinet is 286 mm deep. Each speaker weighs 15.6 kg. When moving it, plan for a secure grip and protect the floor surface.
How to interpret the stated figures
No tolerance or measurement conditions are supplied for the stated 36 Hz-40 kHz frequency range. It therefore should not be compared directly with figures for speakers measured under different conditions. The specification describes the stated reproduction limits, but not how evenly the speaker performs across that range.
The voltage, power, distance and impedance conditions for the stated 88 dB sensitivity are also unspecified. When choosing an amplifier, the overall matching of the system is more important than this figure alone.

FAQ
What is this speaker intended for?
It is intended for a home stereo system with a separate amplifier. Its narrow cabinet is useful when a smaller speaker width is preferred.
How do I connect it to a stereo amplifier?
Connect the speaker to the amplifier’s speaker output using speaker cable. Because it is passive, it cannot be connected directly to a line-level audio source.
What kind of amplifier should I choose?
The store recommends a quality amplifier rated at more than 50 W, but this is not a confirmed minimum power requirement.
Can the speaker be placed close to a wall?
The front port provides greater placement flexibility, but walls can still affect the bass balance. Determine the final distance by listening from your usual seating position.
How should I begin positioning the speakers?
Place both speakers at an equal distance from the listening position. Level the feet, then adjust the distance from the walls and the angle towards the listener in small steps.
