The AEROFON is the masterful result of more than 40 years of painstaking research into the design and manufacture of loudspeakers employing full-range drivers and horn enclosures. The developer of the sublime AER drivers, Filip Keller, is one of the foremost international manufacturers of full-range loudspeakers, whilst Markus Boldyreff is one of the leading developers of innovative horn cabinets. Both men are united as one, relentlessly travelling towards the limit of what is feasible through their unwavering pursuit of the optimum in sound reproduction.

Open Baffle Horn with BD3B

The Excenter is a new horn speaker which not only looks unique, but sounds unique. The impressive power and intensity with which the large Excenterhorn reproduces music is reminiscent of the colossal sound of speakers with a large membrane area or large emitters, however, they far outnumber them. Playback is dynamic and detailed; instruments and voices are reproduced with remarkable finesse, plasticity and authenticity.

Open Baffle

During the development of the Custom, the focus was on transparency. This applies to both its reproduction and design. Not only does it sound fantastic, but it also blends in perfectly with modern living room designs. The Custom delivers great sound, but keeps a low profile when it comes to its look, thus exactly conveying the idea of a contemporary open baffle speaker.
