The acoustics use a 2” compression driver with beryllium membrane and a pair of 380 mm (15") woofers with a paper diaphragm. Although the approach seems a bit old-fashioned, the time alignment system with a flat impedance curve guarantees ideal coupling even with tube amplification.
The speakers of this brand are distinguished by their powerful, detailed and natural sound. With the right amplification, they are able to fill a huge room with sound.
According to the developers, the sophistication of this model lies in the quality and realistic sound. And of course, you can't ignore the unusual design.
The Blumenhofer Classic 1722 is a vintage—style bookshelf speaker. The case is made of MDF 18 mm, Bass Reflex systems with front phase inverters.
Blumenhofer Classic 1733 is a floorstanding loudspeaker. The case is made of 18 mm HDF, Bass Reflex system with front-mounted bass inverters. It is covered with a veneer of valuable wood species.
