The third character of the model denotation refers to the type of product H (horn), the first group of digits denotes the height of the particular model, whereas the second group of digits indicates the depth of the cabinet.
- diameter of the bass-midrange unit; H, W, D – height, width, depth

BVH 110 and 120 are designed to be set approx. 70 cm away from the rear wall. They can be placed closer to the wall for bass reinforcement. The mutual distance between the loudspeakers is not crucial unless the room in itself is problematic.
For those who do not have the possibility of keeping the loudspeakers at that distance away from the wall, we have designed FVH 125-45, the back side of which can be placed next to the wall. Driver units and the type of construction are selected so as to equalize the bassrange, without any shift in the midrange and treble.
The cabinets are mostly made of 18-30 mm MDF plates. Most often, cabinets are veneered in African
kotto (lighter veneer) and mahogany (darker veneer) or at customer's wish. Basic models are obtainable with a nitro-cellulose lacquer or polyurethane paint finish, and upon request with a car paint or even shellack finish (more grinding and several coatings). Upon request, the cabinets can be finished in vinyl, leather, cork, artificial and natural marble or any other material that does not disturb the inner constructional parameters.
The exclusive series (SE) is made of real wood (Pine, Larch, Maple, Walnut, Cherry, Steemed Beech).
Notch filter AD712 for levelling of
strong peaks in problematic rooms. It uses only
one transistor in series, whereas the rest of
the assembly is in parallel (it has no effect on
the quality of the signal). Regulation of
frequency (100-400 Hz) and amplitude (0-12 dB).
Device has it's own housing, uses its own power
supply and is installed between the preamplifier
and the amplifier. In case of integrated
amplifiers, a special circuit board is installed
within the existing device (when the filter is
no longer needed, the device is easily returned
to its original condition).
