It all started with a pair of old midrange Isophon drivers I purchased on ebay honestly without really knowing what I'm doing. i mounted them on small cardboard baffles and was amazed how open the sound was compared to my transmission line speakers I was using for about 12 or 13 years. Of course there was no bass at all. After this short insight into open baffle design the idea what could be possible didn't let go of me. I looked out for a affordable driver and read about the CSS FR125S, I think it was on the site of Tom Zurowski. Fortunately the driver was available here in Germany and not so expensive. Next thing was to find a baffle design. I wanted to play it safe as a newbie and decided to go for the JELabs (http://members.myactv.net/~je2a3/open.htm) design:

This set up was satisfying and offered sufficient bass for me. Listening to music was fun again. After about a year or so I realized that something bothered me a little and that was a kind of harshness in the high frequencies spoiling long and relaxed listening sessions.
So my research began all over again reading articles on all those websites when I remembered an article on TNT-Audio about Hawthorne Audio and their Silver Iris 15" coaxial driver.
The TNT-Reviews can be found here :Silver Iris solo (http://www.tnt-audio.com/casse/ha_si_part1_e.html) and here:Silver Iris duets (http://www.tnt-audio.com/casse/ha_si_part2_e.html).
Some further reading convinced me that the Silver Iris could be the right driver for me and i ordered them at Hawthorne Audio. First thing was to mount them in my existing baffles:

Now the Silver Iris don't need a large or wide baffle and in my small listening room I had the feeling after a while that they didn't reach their full potential in those rather large JELabs baffles. Next thing was to go down in size:

I'll continue later sometime.
