I am now on my second permutation of these - Well not exactly, if you count all the mobile speakers that incorporate this design, but for the focus of this discussion consider only "stationary" designs. When I was still in high school, my friend's older brother had a house, wife and kids as well as a kick ass stereo. Top end Sansui electronics and a pair of beautiful large DIY speaks that were an "end table" design. 4 cu-ft easily and he indicated that he used a 12" coaxial driver. It remains one of the best systems I have heard. Don't know which one he used, but I remember that they were real popular as bare drivers in the electronics catalogs (Allied, Layfayette, Olson) of the times. Some had these gracefully curved die cast alum frames and by and large they looked pretty good. This was 35 years ago. Recently Adire did the HE 8.1, 10.1, 12.1 series that were well received, and if Dan Wiggins thought the design had merits, then at least I am in good company - So, I am a fanboy and I know that David and Larry have heard these too. Anybody else? Especially you old guys? What did you think, what do you remember? I am convinced that the "point source" concept is a good one. What has been your experiance?
