        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.

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 Saturn is an outstanding High-End Hand-Crafted tweeter, based on ZR-25N. It has a total of three neodymium magnets which produce very accurate transients and higher velocity of frequency following.

Many people mistakenly think that the sound of the tweeter is important only above the low-cut frequency. To achieve the best sound-stage possible, the tweeter should be in tune with the mid-woofer and supporting it. They must work together in harmony. Immense research has been invested into solving this problem.

The housing of Saturn allows the tweeter to be vertically moved up to +/-30 deg after it was installed. This means that the sound-beam of the tweeter can be adjusted, enabling the achievement of the perfect listening point with the mid- woofer at any distance. This massively improves linearity and makes the sound much clearer and more natural.

It is constructed to have a great dynamic, yet the sound is not aggressive at all. The vocal of the singer can be heard so pure and rich in details, as the singer would be right in front of you. The massive improvement compared with other tweeters can be heard in the sound of cymbals. With most of the tweeters, when the drummer hits the cymbal with the stick, you can only hear a hissing sound "sssss". With Saturn, you can hear and almost feel the strike. The sound expands in the room and floats around you long after the strike. When the voice of the singer is soft and gentle, Saturn projects it perfectly with its natural-silk cone. The sound of this tweeter is so unique and recognizable, that it cannot be matched by any other tweeter on the market.

 

 

 

 




ZR No.1 is our top-of-the-range Hand-Crafted mid-woofer. It is a masterpiece in design and the best-sounding speaker that we have ever produced. It combines all the best characteristics of our speakers.

The sound is typical ZR-sound: accurate bass, warm and transparent mid-high range combined with extraordinary dynamics. The speaker shocks you the first second that you take it out of the box. Instantly it can be felt that a lot of care and attention has been put into perfecting all details, because the build quality is amazing. All surfaces are silky-smooth and only the best materials are used. The speaker also looks spectacular, and because of its Stabilit basket, it feels warm and natural in hands. All metal parts of the resonance-free basket are hand-polished to perfection and gold-plated with 24K gold.

Immense research has been invested into testing different magnets for the motor of the speaker. The best results have been achieved with four neodymium magnets. The cooling system for the spider is also specially designed. It reduces the compression of the air in magnetic motor to a minimum, which results in richer and more natural sound. The cone has also been specially designed by ZR Speaker Lab just for this speaker. It is hand made from Kevlar and weighs only 2.3g (uncoated). The deviation of weight between cones is only 0.05 g (each cone is weighted). The production of these speakers is very limited.

The dynamic of the speaker is amazing in full sound spectrum. It works great with any amplifier, which includes 3 W "triode" tube amplifiers. Special care has been put into perfection of the mid-section of the sound spectrum. This means that the voice of the vocalist and all other instruments sounds warm, rich and natural. When you listen to the contrabass sequence, you can hear its whole wooden volume, not only base notes. The sound of the string expands in the room and floats around you for a long time in full dynamics (quiet-loud-quiet). When listening to the snare-drum you can easily hear the strike of the wooden stick on the membrane and the vibrations that spread out of the drum. Just this speaker alone transforms a very good sound system into something that leaves you breathless every time you listen the music.
