Invisible Speaker Lounge

There exist really beautiful and elegant design speakers, as we well know from our own history from the late 1990s. With our sleek and timeless upright Ceratec Classic speaker models, which still look the same, but over the years have undergone technical improvements, we especially meet the female taste. About 10 years ago we started with the development of our invisible speaker range. A paradigm shift, but ultimately a logical decision. At that time there were about two or three competitors, which also occupied themselves with invisible speakers. However, what motivated us to work on our own product line was the fact that all hitherto existing solutions, even though having overcome the hurdles of invisible installation, were sonically not really convincing.

Being rooted in the loudspeaker development sector it therefore was our aim to create an invisible speaker who really had the qualities of a normal dynamic speaker. This also included the possibility of using conventional amplifiers. Although other manufacturers were on the same path, we instead wanted to focus on a group of customers who consciously would perceive tonal differences and for those invisible speakers resembled a sonic „no-go“.

Invisible speakers from cerasonar – a reasonable solution for all music lovers, whose female partner doesn’t like „large“ speakers in the living room. And this without compromising the aural pleasure.

Every visitor will be surprised where the full and fat sound comes from. And the owner will  be delighted that the sound not only is full and fat, but very natural even without the use of special amplification.
