  Introduction to ribbons
    There isn’t any jargon here and we have tried hard to steer way from the clichés and exaggerations that seem so common these days on audio websites. With this in mind, this page is divided into sections which are deliberately brief. However as the site evolves it is highly likely that enhanced and expanded descriptions will be available.
       
    What is a Pinsh ribbon driver?  
       
    It is a single strip of pure metal moving in a magnetic field. The mass of this strip is 0.006 gram i.e. 167 times lighter than the most expensive dome tweeter. The moving mass of our midrange is 0.024 grams i.e. 125 times lighter than the most expensive conventional midrange.

The ribbon is immersed in a powerful magnetic field which exerts a vice-like grip control over it so that the ribbon stops and starts precisely in time with the signal from the amplifier.

The metal strip can withstand temperatures in excess of 550 degrees centigrade. Furthermore it acts like a heat sink and direct radiator cooling itself with its rapid movements (like a built-in fan) since the atmosphere is in direct contact with both sides.

The above description covers our bass, midrange, tweeter, super tweeters, hyper tweeters and ultra tweeters. Yes we have a successful full range pure ribbon bass speaker.
 
       
    What are the technological advantages of ribbon structure?  
       
 

There are no additional moving parts like spiders, domes and voice coils and formers including adhesives – all of which have thermal limit. Our zero- store ribbon has no damping, neither is it enclosed in a sealed chamber, both the front and the rear of the moving metal strip are in direct contact with the atmosphere.

What are the audible advantages of ribbon technology?

Distortion is exceptionally low to almost zero and not ordinarily audible. This means that the other components in the audio chain become the primary sources of signal distortion.

The frequency response is linear and the upper limits are 100khz, although the human ear can hear up to 20,000Hz there are super harmonics called formants of the lower frequencies that when present gives you the sense of completeness of the sound. Or put differently, when absent, the sound feels more hi-fi and less natural.

 
       
    What about our ribbon/ bass hybrids?  
       
    Currently most Pinsh loudspeakers use cone drivers for bass response with properly designed crossovers to enable seamless integration with the ribbon mid and treble drivers.

Some Pinsh models use transmission line loading for the woofers. This is because it’s s the only enclosure that does not restrict the movement of the cone and does not add colouration to the bass. We have chosen a cone material that is very rigid at the appropriate frequencies of its function.

A transmission line is basically a long tunnel, at the one end a cone driver is attached and the other end is open. The tunnel is tuned with 100 per cent pure sheep's wool, so that the sound is allowed to escape gracefully at the other end. This mechanical technique provides an additional half an octave of high quality bass when compared to the free air resistance of the driver.
