Specialties at the tanara:
Among other reasons we went without 22mm MDF to achieve the fineness by using the much more expensive 18mm tank wood. Tank wood has through it’s higher density significantly better characteristics at mid to high range then MDF. Also it is more stiff even at low material thickness.
The tanara uses planar drivers for the midrange and the tweeter. They are mounted in a totally separate internal housing, so a housing inside a housing exists. Resulting an excellent isolation between bass section and midrange/treble is achieved.
Two drivers for the bass are mounted horizontally and do work in a common chamber. This construction allows a close to 100% elimination of the unwanted vibrations of the bass drivers. At the same time the isolation to the midrange/treble section and to ground is getting significantly better.
The concept of the behold tanara forces partly active driving (bi-amping). No crossover to separate bass to midrange/treble is present. The crossover frequency lies at 211Hz. The tanara always needs to be driven with an external active crossover.
For the separation of the midrange to treble at passive crossover at 2kHz is build-in. To achieve the relative high electrical decay of 36/32dB per octave of those filters two 6-pol LC-filters are used. A filter bank of that kind normally cannot be found at other speakers and never within this range of price. To get the necessary coil quality only Mundorf air coils (type 140 and 200) have been employed.
While using a Gentle G192 driving the tanara all the unavoidable discontinuities of the drivers and passive crossover regarding to amplitude, phase and delay are eliminated to almost zero. Inevitable this leads to a quality in playback of music competitors get stuck at the beginning having this price segment in mind.
