He did get a patent a long time ago when he was a young fellow at McIntosh. After reading Taylor & Griffin, it is obviiously full of holes.

True. Oh, how true.

Of course, only problem with a curved array is, er, it's a curved array, not a line-array, so you loose some of the major benefits (giant stereo sweet area rather than tiny sweet spot etc). I'm not suggesting they sound bad -far from it, but they do have their limitations.

I still don't buy these Jordan / Bandor mini arrays. Massive respect for TJ though I have, not even he can break the laws of physics.

With a 4 unit array at about 8" tall is fairly easy to get into the far field if you have a largish room. At that point it acts much like a 2x8" oval.

Those that have tried more find that 4 is about the limit of the number you can stack.

Roger got da patent number rong

I like the idea of a focussed array. I have used 6 X 5.5 inch drivers in a vertical line on a largish open baffle and they do integrate around 12 feet away.
I now have 9 X 5.5 inch drivers. I was thinking of a 3X3 array, curved slightly in both vertical and horizontal axis to focus the sound at the listening position. much less room interaction I think from early experiments.
The downside is a small sweet spot.
upside is:
9X powerhandling
much more efficient
lower distortion (smaller cone movement)
9 holes to cut + srews and etc.

puts the full back into full range

Good point Dave. Reckon I'd still rather have a larger driver though. ;-)

I had the joy of hearing the 2" Jordans 30 years ago, they were an amazing little driver. In a vertical straight array of 4, the vertical dispersion was very narrow, height was critical. And they lacked lower midrange "bite" needed for sax etc. IMHO

It seems though, if the array is much higher, a true cylindrical wave front is created, and dispersion is no longer an issue.

Out of my budget. More $ than my first home.
