Many lovers of music have one problem in common: they want to listen to good music at a high quality of reproduction but they do not have the room to place the loudspeakers they would like to buy or they cannot find the right speakers to blend in with their furnishings and taste. What they need is loudspeakers that do not look like loudspeakers.

And so we developed the PORTRAIT design, which can be hung on the wall and looks like a picture. The objective was to keep the cabinet as flat as possible. The PORTRAIT will be satisfied with only 40 mm in depth. If you take the time to make some more complex cut-outs, you can even reduce this to 34 mm.

This is made possible by the use of particularly slim 13 cm FR 12 - 8 Ohmloudspeakers as woofers. Combined with the SC 5 - 8 Ohm tweeter and the specially designed crossover, this produces a sophisticated satellite speaker unit. Due to the small cabinet, low bass cannot be produced by the PORTRAIT. As a result, the bass range below 100 Hz is best covered by a subwoofer (e.g. SUB-W 20.39 ).

This combination with a powerful subwoofer means that the PORTRAITset-up is a visually appealing and acoustically highly effective system which can, if required, be extended. If the wall space in front of and behind the listening position are free, additional PORTRAIT speakers can be hung to produce a multi-channel system for home theatre and music.

The point about the PORTRAIT is the option of fitting a fabric front to the cabinet which can vary, depending on the surroundings, e.g. single-coloured or brightly coloured silk. Of course, one can always put one's creative skills to work and make one's own silk covers adorned with favourite motifs. There are no limits to your imagination.
