I started looking for a new pair of drivers to replace the Fostex for my Mets and since past 3 months have been looking around. Though there were plenty of options, the one that could fit the requirements of parameters, cost and delivery was not more. Typically its said that if you look around too much for a particular thing, then at the end you purchase more with your heart and intuition rather than your head and logic. I think this is what happened to me when I ordered the Soviet era driver from the 1980s. I have gone to the extent of looking at Lowther, Voxativ, AER drivers which was miles above my budget. Also considered many vintage Alnico types etc. But the Alnico would require a subwoofer as they are more for mids and highs. Also was reconsidering Fostex and the Dayton point source full ranger. Both the Fostex and Dayton are more technical sound and I knew what to expect from their associated hype. Finally came across this driver. It was purchased on intuition and there are plenty of DIY speakers with this driver ranging from BLH, Horn, TQWT, Sealed, OB etc. This driver like any Russian product is built like a "Tank" with a thick cast iron basket (no painting) and looks pretty heavy (unlike the thin basket used in Chinese driver which needs to be painted to avoid rusting).
Like my project this driver is also DIY. Typical TS parameters are not given much importance. More importance to the driver material - paper used, suspension used, glue used for sticking the spider, suspension and cone at the voice coil. Details of the voice coil, guage of wire used, number of turns, number of layers etc. are mentioned in the specs other than the usual TS parameter. Also surprisingly, harmonic distortion of this driver gets mentioned above all. Another surprise when I ordered this driver was - the seller asked me if I want some changes in the driver like the suspension used and the colour of the suspension required. So this driver is not over the shelf, but is made after ordering - a true DIY driver but has many followers in Russia.
The driver after its modification will be shipped in a weeks time and will post impressions after I have worked with them.
Thanks for looking.
