Who makes the best "Coaxial" Tweeter/Midrange design?

Pretty much the same guy, but I'd go with T.A.D

Andrew Jones,  was with Kef,  He did the Elac and I believe Pioneer owns TAD, but Andrew does it all there. 

You know, its been 5 + years since I've seen a pair, but I've modified a couple of different pair of cheap speakers from Best Buy... It was an Insignia  NS-B2111.  They needed parts improvements, impedance correction and some diffraction control, but man, these things ended up singing quite well. I think I paid about $60 a pair for them. My brother still uses a set with a sub as his main speakers.

I changed the crossover a bit (changed slope, all polyprop caps, better coil), added zcomp, added felt to the tweeter ring and stiffened the cabinet.... 
You would fall over with the difference!
