David Dlugos wrote a very nice web site which explains the principles of transmission lines speakers, You'll find there interesting information about Kef drivers (like the B139). I want to thanks Axel Oberhage for the valuable information and correction he provided. 2 other websites I wrote : marklev and frenchimages. Check them out !

Thanks :

I would like to thank here all the friendly people who helped me to build this website. Thank you for the pictures and information you sent me. All the IMF speakers owners are very happy with their speakers, and still use them, except when their wife needs room in the house :) Thanks everybody !

I'm looking for a pair of IMF, if you live in Europe, drop me a mail !
