Scansonic MB3.5B Floorstanding Speaker

5 700,00 €

The Scansonic MB3.5B is a slim 2.5-way floorstanding speaker for medium-sized and larger rooms. Its side-firing 6.5-inch bass drivers allow the cabinet to retain a narrow profile while supporting the low-frequency foundation. A ribbon tweeter complements two drivers with carbon-fibre cones. An amplifier rated above 50 W is recommended.

Description

The Scansonic MB3.5B floorstanding speaker is designed for medium-sized and larger rooms. Its slim 2.5-way configuration combines a ribbon tweeter with side-firing bass drivers, allowing the front of the cabinet to remain narrow without giving up dedicated low-frequency support.

Driver System and Crossover

High frequencies are reproduced by a sealed ribbon tweeter. Two 4.5-inch mid/bass drivers use carbon-fibre cones and are connected in series so that they can handle more power.

Two side-firing 6.5-inch bass drivers with aluminium cones complement the front drivers. They operate up to 150 Hz, while the upper crossover point is set at 2600 Hz.

The crossover uses high-quality components and is tuned to minimise its effect on phase. It also corrects the frequency region influenced by the geometry of the cones and cabinet. The purpose of this tuning is to achieve a natural, balanced frequency response rather than emphasising a particular part of the spectrum.

Cabinet and Placement

The curved cabinet is heavy and extensively braced, including carbon-fibre reinforcements. This substantial construction is intended to keep cabinet resonances under control. The vented enclosure uses a forward-facing bass-reflex port.

Because the port faces forwards, its airflow is not directed straight towards the wall behind the speaker. Even so, sufficient open space should be left around the cabinet for unrestricted air movement. In particular, do not place the side-firing bass drivers directly against walls or furniture.

As a starting point, position both speakers at a similar distance from their respective side walls. You can then adjust their spacing and distance from nearby surfaces while listening to bass balance and soundstage presentation from the main listening position. Adjustable aluminium feet help level each cabinet on the floor.

Amplifier Selection and Connection

This is a passive loudspeaker and therefore requires a separate amplifier. Connect it to amplified speaker outputs using speaker cable. When wiring a stereo pair, maintain the same polarity for both channels.

A high-quality amplifier rated above 50 W is recommended. This figure is an amplifier recommendation, not a statement of the speaker’s maximum permitted power. The specified speaker impedance is greater than 5 ohms.

The stated sensitivity of 89 dB is provided without measurement conditions. Amplifier selection should therefore take account of the load presented by the complete speaker system and the listening level required in the room, rather than relying on the sensitivity figure alone.

Frequency Range and Finishes

The quoted 27 Hz-40 kHz frequency range is published without a tolerance or measurement conditions. It should be treated as a general specification rather than a promise of a particular audible level or bass result in every room.

Available finishes are silk-matt black, silk-matt white and matt walnut. The dimensions and driver system remain the same for every finish option.

FAQ

What amplifier do these speakers require?

A high-quality amplifier rated above 50 W is recommended. It should operate reliably with a load greater than 5 ohms.

How do I connect the speakers to a stereo amplifier or AV receiver?

Connect them to the amplified speaker outputs with speaker cables. Do not use a line-level output, because the speakers do not contain built-in amplification.

How much space should I leave around the cabinet?

Leave clear space on both sides because the bass drivers are mounted there. Choose the final distance from nearby surfaces by listening from the main seating position.

Why is this described as a 2.5-way system?

The side-firing bass drivers supplement the main drivers only in the lower-frequency region. The design is therefore not classified as a separate three-way system.

Does the 27 Hz lower limit guarantee the same result in every room?

No. The published limit does not include a tolerance or measurement conditions. The room and the position of the speakers also affect the bass you hear.
