The Holophony Number Four are bookshelf loudspeakers made of 27-mm oiled bamboo plywood.  This is two-way configuration, but is able to reproduce the full frequency range, even in low tones. It has 7 dB lower sensitivity than higher models, but can handle more power (20W instead of 15W). All specifications are given in the table Pricelist.

Included in the set are isolation ball feet Receptor, for additional payment we offer anti-vibration stands:

H4b-1s H4b-14s

H4b-6s

H4b5s

H4b-4s

The optional stands with a total height of 60 cm have a weight of 18 kg / pc and are provided at the bottom with the highest class magnetic feet (lifting loudspeakers on the air cushion), and at the top with wooden balls from feet Receptor No. 1. The lower and upper platform of the stand is isolated from its column with anti-vibration material. The column of the stand is filled with a mixture of lead and anti-vibration materials.

The bottom of the loudspeakers has the same recesses for the balls as the top of the stand, which protects the loudspeakers from sliding off the stand even when it is pushed. As a standard, we use 4 balls, but in the case of difficulties with getting full adhesion of each of them, we use 3 balls (a fifth, middle recess is used for this).
