| Welcome to the home page of Pinsh loudspeakers. This site is quite comprehensive already and is growing steadily under carefully controlled conditions. Our objective here is to provide you with sensible, relevant and jargon-free information. Afterwards you will certainly want to audition one or more of our models. |

| Before exploring the site, we thought you might want a glimpse or brief insight into what we do. So here is a quick introduction. |

Conventional loudspeakers use a voice coil wound with many turns of conductive metal glued onto a voice coil former usually made of paper, kapton, aluminium etc. This combination is then glued onto a ‘spider’, (a jargon term for a casting or machined block with open sides, a bit like a spider’s web and cone in the case of a woofer and onto a spherical dome in the case of a high quality tweeter or midrange. The average weight of a dome tweeter being in the order of 1 gram and dome midrange of 3 grams.
The frequency response of mid and treble dome units range from 600Hz to 20,000Hz. In simple English this means that the dome has to move 20,000 times in one second, i.e. to move 1 gram only for a distance of half a millimetre 20,000 times, the total distance covered will be 2 meters in a second.
Total mass moved in one second backwards and forwards is 4,000 grams or 4kgs. Due to this problem of mass and the high speed that has to be achieved, there is energy storage in the dome. This results in: |
|
|
| |
 |
Poorer transient response |
|
| |
|
Slower rise times |
| |
|
Higher distortion |
| |
|
Higher power requirements from the amplifier |
| |
Pinsh has solved these problems with their uniquely engineered Ribbon Technology and the results can be heard in the home at surprisingly modest entry costs. |
