ZGZ-801
Closed-box, high-efficiency speaker system
The ZGZ-801 reference loudspeaker system features a closed enclosure design with a volume of 75 liters. It features custom low and midrange drivers with aluminum baskets of increased rigidity with a lightweight cellulose diaphragm, operating in a 3-way system using a crossover of advanced design. The set is characterized by high efficiency, dynamics, effectiveness and smooth impedance characteristics. It blends perfectly with any amplifier.

Unique design
The ZGZ-801 is a rare closed-cabinet design with custom drivers with a configuration inspired by the d'Appolito layout. The set is a 3-way system using a crossover of advanced design.
The result is a loudspeaker system with high dynamics, efficiency and mild impedance characteristics.
All this means that these gentle giants will also play great with tube amplifiers.
Closed-case design
We used a fully enclosed solid cabinet with an internal volume of 75 liters and a 3-way audio path system with dual woofers. This design allows for a fast impulse response, so we can enjoy clear and unstretched sounds, which is especially noticeable at low frequencies.
The closed design also has the advantage of a gently sloping bass response, making the bass more natural and pleasing to the ear. The enclosure used also gives a wide range of maneuverability in terms of positioning the set in the listening room due to the absence of characteristic coloration in the bass section, often heard in the most popular designs.Thanks to the high dynamic range, our set will play extremely clearly both at high volume and in quiet evening playback.
High efficiency and exceptional vocals
The 91 dB efficiency (measured in an anechoic chamber) resulting from the use of two drivers in the lowest band and high-efficiency drivers in the mid and high bands gives it the ability to work effectively with a wide range of amplifiers, both solid-state and tube.
The midrange driver used operates at high power handling and has a built-in phase equalizer. The division frequencies have been selected so that they are not in the range most sensitive to the human ear. This allows us to enjoy a very clear and faithful reproduction of vocals.
Smooth impedance characteristics
Smooth impedance characteristics with no local low extremes, making it possible to connect to amplifiers sensitive to changes in load impedance.
Hi-End Crossover
Advanced passive crossover with a 3rd order tweeter, midrange and 2nd order woofer path design with Zobel circuit and band-pass filter. We used top-notch components, including air coils and metallized polypropylene capacitors, which enhance the linearity of the frequency response with no visible divide in the bandwidth.
Transducers made especially for us
Custom low and midrange drivers with aluminum baskets of increased rigidity with a lightweight cellulose diaphragm. All transducers were made in Poland and Norway according to Unitra engineers' instructions. We used two 8-inch woofers with lightweight cellulose diaphragm and aluminum basket. An 8-inch driver with a woven polypropylene diaphragm and phase equalizer is responsible for the midrange, and the whole is completed by a 27mm textile dome
Double box design
The design of the enclosure is based on an uncommon on the market "box-in-box" arrangement for greater rigidity of the structure. The resulting weight of the set of more than 70 kg has a significant impact on the reduction of vibrations of the enclosure walls and parasitic resonances generated as a result, which positively translates into sound quality.
Finishing with natural materials
The enclosures are finished with natural wood veneer made from selected leaves and hand oiled. In addition to the standard black grilles, we also have more classic ones, for which we used Polish linen.
