BEC AI-70 ลำโพง Column Array ขนาดดอก 3 x (20×120 mm) 60 วัตต์ ขนาดเล็ก เพรียว บาง

The Audio Innovations loudspeakers doesn’t have conventional dynamic drivers, but “manetostatic drivers” of each 20mm x 120mm insize. In the AI-70 and AI-100, there are three placed one above the other, in the AI-120 there are four. And these are not, like ordinary membranes, driven in the middle, but similar to a magnetostat over the whole surface. The result: you get a large, homogeneous and evenly vibrating surface, which also has the ability to bundle the sound vertically and less horizontally. The principle is known from professional sound pressure, when it comes to filling large spaces, which is usually achieved with a horn design, but where you experience other disadvantages in terms of sound quality..

In the Audio Innovations speakers is the structure itself that achieves the desired effect. Whether you are right in front of the loudspeaker or a few meters away, the noise level varies considerably less than with conventional speakers. This also affects the spatial sense, because the typical stereo triangle with the “sweet spot”, as best listing location, is not here. In the horizontal plane the elegant transducers attain an impressive beam angle of 160 degrees and only 40 degrees in the vertical direction.

In addition to the desired bundling this has the advantage that the acoustics does not have as much influence. Smooth floors or ceilings, which would otherwise lead to unwanted reflections, will not get so much noise in this construction plan, so you will also have less reflected sound but only direct.. Another advantage of the used design: The chassis used has a very linear impedance, which does not unnecessarily limit the performance of the amplifier. This is more for technicians, but it allows these speakers much less critically than others to work with the electronics and therefore makes no high demands on the amplifier used.
