Scansonic MB3.5 B Floor-stander
Sorry, this product is temporarily out of stock.
The MB3.5 B is a slim floor-stander with two 4.5” carbon-coned drivers, a sealed ribbon tweeter and two 6.5” woofers. The MB3.5 B works as a 2.5-way speaker, where the two midrange-woofers are supported by two 6.5” aluminum coned woofers. The two carbon midrange-woofers are run in series for increased power handling. The cabinet is heavy, braced and curved, with carbon reinforcements. The speaker is crossed over at 2.6 kHz and the two added side woofers assist up to 200 Hz.
The MB-series features high quality crossover with top quality components and a complete cable harness from Ansuz Acoustics. The filter has been carefully tailored to linearize the frequency region where cone and cabinet geometry play a role and also to carefully tune the speaker to a natural sounding frequency response.

Michael Lang, STEREO magazine (Germany) May 2015:
"...the floor-standing loudspeakers of the MB Series, the Scandinavian convinces completely. In addition to the virtues of the little sister MB-1, bass foundation and the huge dynamic reserves are two of its best qualities. A bullseye!"
Placing your Scansonic HD Loudspeakers for Optimal Performance
Though rear-ported, your Scansonic HD are easy to place in your listening room. Please follow these simple guidelines:
- In general, Scansonic HD like to be placed far apart, but relatively close to the listener. - Assuming your room can accommodate such placement, Scansonic HD like to be placed approximately 9-12 feet apart (measured from the central, vertical axis of the speaker drivers).
- Imagine a line running left to right from the front of one speaker to the other. This is the lateral plane of the loudspeakers. Now, from the center-point of this line (i.e. halfway between the left and right speaker), place a measuring tape perpendicular to this line, running perpendicular from the lateral plane of the loudspeakers and aiming towards your listening position. Your listening position should be directly on this line, approximately 6'-8' from the lateral plane of the loudspeakers.
Let's start by adjusting the speakers for the proper tonal balance...
- Scansonic HD need to be placed at least three feet from the back wall, i.e. the wall behind the speakers. Place the speakers at least three feet from the back wall and at least nine feet apart. Using a piece of music with which you're familiar, and which has significant bass content, move the speakers front and back until natural, powerful bass is achieved.
- Next, vary the distance between the speakers and side walls. This will allow you to adjust mid- and high-frequencies for proper balance.
- IMPORTANT: although Scansonic HD MB-series loudspeakers need to be placed several feet from the back wall, as described above, they can tolerate placement within a few inches of the closest side wall. Don't be afraid to experiment with such placement of speakers, as spreading the speakers farther apart and therefore close to the nearest side walls is often essential for best spatial performance.
Now, let's dial-in the speakers for best spatial performance, i.e., image focus and soundstage width...
- Scansonic HD speakers like a bit of toe-in. Aim each speaker so it points just to the outside of each shoulder, i.e. the left speaker should be aimed just to the left of your left shoulder, the right speaker aimed just to the right of your right shoulder.
- Once aimed per above, adjust for best compromise between image focus and soundstage size. Increase toe-in to achieve greater image focus, increase toe-out to enhance soundstage width. You may also want to move the speakers slightly closer together or farther apart and assess the effects upon image focus and/or soundstage width. Please note: very small movements of an inch or less can have a significant impact: proceed slowly!
- As per our recommendations included in 'Tonal Adjustments' directly above, Scansonic HDs can be placed within a few inches of the nearest side wall (This is a unique attribute for a high performance loudspeaker). Experiment with moving the speakers farther apart and closer together and choose the location that achieves the best tonal and spatial performance.
