Kiwis (or Aussies), have you tried these?

Found these kevlar drivers...

...by accident.

Scroll down a little. Yellow cones.

Kevlar. Big magnet. The TS params are listed, follow the link.

Anyone used them?

For NZ-available drivers they look incredibly well priced. Remind me of others, but can't think what.

Sorry haven't tried them, but Surplustronics always seems to have some nice treasures every now and again. I just wished I lived in Auckland 🙁

Would be interested to know how the sound if you get around to trying them

Sreten, I did see that link on the site but it kept bringing me back to the same page.

Anyway, here's the Skytronics page:

Anyone in the UK used them?

I have a pair of polys 902.214 in the box for two years now. I would like to measure those yellow cakes. No reference to Le though on T/S.pdf or any information for it's output in frequency. Nice buy and good for testing. You can never go wrong. Next manufacturer close in parameters is a 10" Beyma for double that price but good documentation and better quality and Vas, being the same syze and type of cone. More powerfull for this brand though and to prove it the vented coil in the back. If you buy the 6.5" (fs=50Hz) then is a good main speaker (or mid) or whatever, but be cautioned with the hard kevlar cone.

Here's the WinISD plot for the 6.5" unit.

20l box tuned to 40hz.
