Here is our family of Zeta Zero loudspeakers-all available models, colors and technical specifications and below The Pricelist.

BODY:

All  Zeta Zero loudspeakers are hand made and crafted  from hundreds of  real wood layers and metal -no plastic is used at all in the body. All rights of designs  reserved by international law.

COLOURS:

Loudspeakers are finished in semi-gloss and available in regular price in 4 basic colors:

Black, Sahara, Deep Bronze/Chocolate (almost mahogony), as well as Full Colorless. Two of them-deep bronze and colorless are  transparent so you can see  beautiful lyers and the structure of  wood.

Also available by request  and  by extra payment other  colors and full gloss.

 

ELECTRONICS:

Not only do we make loudspeakers, but we also create also extraordinary audio home cinema electronics including multichannel audio/video preamp and special analog power amp-see below. These electronic gems are dedicated only to the most demanding audiophile listeners. These are based on so called reference measurements  and professional level  electronic circuits.

                                           

 

 

 

DRIVERS and  Leads:

                                                      

One of the most powerfull and most complicated ultrawide-band ribbon loudspeaker-drivers ever made. Build  of well over quarter of a thousand of components and advanced 21st century materials. Fully computerized. And featuring a self-cooling active system.

And  our specialultra high current leads are over 1" thick ; silver-plated;  4-way for  bi-wiring.   This lead is made of up to 8004  silver plated copper strings for the best possible sound properties. No compromises in Zeta Zero. We do this  lead for custom orders.

Our bass drivers- powerful ultra low frequency bass units for our new version MK2 and MK3  Zeta Zero Venus Edition. The first driver's power - 2500 Watts. The amplitude of movement (Xmax)- as much as 100mm! The weight - over 21kg.

 

Our second ultra bass driver is probably the most powerfull 15" bass unit on Earth! 3000 Watts RMS and 8000 Watts music power ! The weigh of this bass monster- 47kg !

 For comparison, other companies use  bass speakers of power up to about 300 Watt and  Xmax  up to 15mm. 

Compare it to 100mm  of   bass speaker used in Zeta Zero!

These drivers gives you an unbelievable dimension of deep bass that even  the best modern 3D public cinema can't compare with!

TECHNICAL PARAMETERS:

 

Before we present our models and important parameters, we would like to show one small but very interesting and significant topic from the audio measurements of Zeta Zero loudspeakers. 

 

The actual frequency response plot of high frequencies  of our ribbon drivers from our Venus  model speakers. The actual measurements were done by a reference capsule Bruel&Kajer model 4136  and for comparison 4135 + professional 200V B&K conditioner and preamp Bruel&Kajer model 2606 and 2010 with frequency response up to 200kHz and digital graphic representation made by audio laboratory measurement digital system "Clio".

As you can see it, is unusually flat with a gently decreacing response up to nearly 90kHz! The reason- the ultra-wide frequency response  of the transducer. It is vitally important to get  realistic true  high quality sound because "the magic" of sound is hidden in the so called "harmonics" often located much higher than the basic acustic frequency of a signal. For example, the harmonics of a real violin are still present over 2000 kHz! Even in the best world class loudspeakers the frequency response limit is often around 30 to sometimes 40 kHz. What is worse, often on much lower frequencies usually one octave down (sometimes on as low as  14- 18kHz) there are very harmful  strong resonances, and over them the frequency response plot falls nearly vertically down.

 

Here  in Zeta Zero we have  a response from Heaven. No resonaces, no limits on 20 or even 40 kHz, and a very genlty falling  line  up to around 90 kHz. Perfect plot response for Perfect Sound !

 

This is one of our Zeta Zero sound secrets- this ultra-wide and extremely flat frequency response  up to that magic 90 kHz. This frequency response pared together with the extreme power and durability of Zeta Zero are two factors usually not found together in loudspeakers made by most of our world competitors !

ZETA ZERO model "GOLIAT"      

Zeta Zero Goliat-  Big. Ugly. Not at all in keeping with the artistic, human shape of our other speakers, but...VERY powerful!    It is a unique system of first class home speakers with two dedicated dual external amplifiers and an external electronic "phase driver". It effectively combines audiophile quality, exceptional frequency response, impulse response and perfect sound with  impressive power- Model A – 2,8kW(2800W) of continuous RMS power; Model B - up to 6400W RMS. 

Due to a record amplitude of the kevlar membrane movement (Xmax up to 75mm) of the powerful main sub-bass drivers  and built-in patented magnetic brakes, it is probably the only high-end set in the world with an unprecedented ability to play ultra-bass sounds and stimuli with stunning power and precision.It generates lower than 16Hz in practice and as low as nearly 11Hz. It is able to deliver authentic concert sound intensity of, for example, pipe organs even at frequencies close to infrasound. It can provide the listener with an unforgettable and exciting experience on the borderline of vibration so desired by every discerning music lover and audiophile. Ribbon Tweeters are built on technology and materials from our flagship model of "Zeta Zero New Age".
