Architect7, great to hear from a fellow Open-baffle enthusiast.
I would like to read more about your open-baffle experiences - your successful or promising designs and your open baffle plans and projects you believe might need some more refinements.
BTW, in the open-baffle arena, I'm currently working on a speaker using three stacked BG Neo10 midranges (cover midrange about 250 Hz to 3 kHz – see DIYAudio (“StudioTech” postings) and see Parts Express for info on this midrange driver), a RAAL 140-15D ribbon tweeter with the optional amorphous core transformer, and a 15'' B&C Neo woofer covering down to say, 70 Hz, to limit woofer cone excursion and use reasonable EQ. Below 70 Hz will use Velodyne DD-15 sub where I believe it's usually better than most open baffle subs – IMO, unless you spend megabucks on big drivers, highly EQ'd open baffle subs tend to have just too much distortion below about 40 Hz.
Hope to see future open-baffle posts. As for me, I'm rather busy and can't post very much these days.
If I do post more about my open-baffle project, I wonder if this thread is considered the proper place
