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.
The Blumenhofer Concert X is an acoustic model that features a wooden horn and beryllium tweeter for a natural and detailed 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.
