Product Description

     ZR Speaker Lab is a small company based in Slovenia, Europe. It is specialized in production of only High-end, hand-made speakers and audio devices made from the highest quality materials. The production is limited. It is well known worldwide for its unique sound and designs.

The company was founded in 1983 by Zvone Raspor. He has more than 30 years of experience in audio field.

   
        Zvone Raspor in 1983

Everything started with the speaker service, which gradually grew and turned into speaker modifications. Since then he repaired or modified more than 15 000 speakers and many other audio devices. This gave him a very a powerful insight into every possible problem or wish that customer has about the speakers

He was teaching the flute for more than 8 years, had his own band, and collaborated with many musical groups.


Zvone Raspor today

By doing this, he gained a profound knowledge about how real instruments and vocals should sound like. He learned many important things about sound that cannot be described by conventional parameters. That perfection of sound is brought to reality through his speakers..

The philosophy of the firm is to implement the knowledge gained from the arts into the science of speakers. ZR Speaker Lab strives to give to the speakers this intangible component, which can only be described as "soul". The result is the product that can be felt and sound that one can never forget.

 

 

 

 

 

 

 




ZR 25N is an impressive High-End Hand-Crafted dome tweeter with natural-silk cone. The base of this tweeter is ZR 25 C, but it uses neodymium magnet.


 

In a flood of hissing neodymium tweeters it is very hard to find the tweeter which would have High-End characteristics combined with a great sound. This was our primary concern. The cone is impregnated with specially developed mineral coating. This reduces the parasitic resonances of the cone and sharpens the sound-stage. In combination with the specially modified copper-ring, the distortions are drastically reduced. This effect can be especially noticed at higher volumes of amplitudes. To achieve the warm mid-section of the sound-spectrum, the modified “Helmholtz” resonator (by ZR Speaker Lab) is used in combination with the special damping of the housing. The housing of the speaker is made of Inox-Stabilit (or Aluminum-Stabilit). In this way, resonance-free housing is achieved. The protective grille of the speaker is anti-magnetic, so it does not interfere with magnetic field of the magnetic motor. This helps with the linearity of the speaker. The silk cone also contributes to warm, rich and natural sound with amazing dynamic and transients. This allows you to hear the cymbals of the drums like cymbals, not just the hissing sound “sssss”, like with most neodymium tweeters. With ZR 25N you can hear and almost feel how the drummer hits the cymbal with the stick. You can hear how the sound spreads in the room, filling it with passion that he feels about his instrument.

 

 




ZR 18 DD is a state-of-the-art Hand-Crafted, direct-drive mid-woofer. It is probably the best known speaker from ZR Speaker Lab since 2004, when it was introduced for the first time. Direct drive without crossover enables the speaker to operate without phase-shifts, and with maximum dynamic combined with the live sound-stage.


 

All components of the speaker are chosen to be in tune with each other, giving the sound that is impossible to get with any-other speaker. The main components are light-weight cone, resonance free basket, optimum power of the motor, quick and precise voice- coil and specially chosen spider. It effortlessly follows the amplitudes of the amplifier, which results in transparent sound with extraordinary dynamic in full range of the speaker.

Paper has been used for decades as the best material for the cones. It has that special, natural sound that the new materials just cannot produce. Immense research has been invested into maintaining the sound of the "old school" paper cone, while simultaneously eliminating all of its weaknesses such as parasitic resonances etc. To achieve this, the cone is impregnated with two different mineral coatings, specially developed by ZR Speaker Lab just for this speaker. This gives the soul to the speaker and the sound that no other speaker on the market can match.

The voice of the vocalist can be heard in front of you naturally and purely. You can easily hear how the singer breaths, and from the details of his or her voice you can feel what he or she feels. All instruments sounds completely natural and the richness of the sound is sensational. Time delay of the concert hall slowly expands in your room, transforming it into a concert hall. It is the sound that you will adore and just want more of it.


"... The music almost "jumps at you" when playing these speakers... It is unbelievable how natural it sounds... "

 

 




Cx2 is a two-way Hand-Crafted stereo passive crossover (optional dual mono). It has a regulation of high-pass volume level so the optimal volume level between speakers can be achieved.

Noble materials (stabilit, aluminum and brass) give this crossover unique look and natural feeling when it is held in hand.

The unique design doesn't stop at the outside. It is a crossover in the full meaning of the word, not just a full box of capacitors and coils. The primary focus is the quality of sound, so it is designed to give to the speakers exactly what they need; nothing more or less. Each cut of the crossover is the same as we would cut the real picture, and then glue it back together. This crossover makes the cuts almost invisible.

It also has specially chosen highest-quality polypropylene capacitors. Each-one is measured separately. The tolerance for capacitors is +/-1%. Each voice coil is hand-wound and also measured in precision of +/- 1%. The components of this crossover have been tested for years and many satisfied customers are still using them today.
