Yes, once they start showing up in cars you know they're cashing in. Mark Levinson, HK, of course 8ose. I wonder if it's still: 1) Founder with passion sells quality 2) His children run the company for a while and they sell variations of the same thing 3) Founder dies and his adult children sell the company off and the buyers turn the products to trash.
Right now I am building a 7.1 setup using the ACI Sapphire IIti for every upper-range speaker except the center that I made myself. The 30-year-old L & R Sapphires have beaten anything I have designed including the rather good MTM surrounds I just threw out. Almost there - Found a fresh pair of stock Sapphires for the sides, and the used 7K-011DBl drivers are mounted in a duplicate cabinet for each of the rears. If the 7K011-DB's are communist knockoffs I'll put them in my center channel so all the speakers will have that 80's kevlar look.

There was number of kits with the 7K011 DBL. Focal did one called 133 if I remember correctly. Mike Dzurko's mix with Scan tweeter was quite nice. I guess with current tweeters being able to cross below 2k, the 7K011 DBL could make not a bad loudspeakers, but don't expect a lot low end from them. The new version is 7K 4211DB from '98 on.
Focal was one of the most popular brands for diy including Poland in '80 and '90. I bet they are as French as they can be. Have pair 5NV4412 a newer version 5N412DBL from '98 that will get new spiders from Poland (STX) and will play music again - very nice sounding 5".

Excellent!
My Audio Concepts Sapphire IIti clone is almost done. The Jack Caldwell crossover is coming together. I substituted a tweeter with a similar impedance curve but less sensitivity so I have changed the resistor values for more output in the high-pass crossover. Hopefully it will see the same curve as the original tweeter had!
I would be interested in tuning famous crossover designs for modern drivers so as to maintain the same qualities as the originals. Great sport!
 
Guys, it just dawned on me - I have the original Focal T120ti tweeters up front with external crossovers. I can get zma readings for the T120 with its stock padding resistors, and for my less-efficient Peerless DA32TX00-08's with no series resistance, and then try to match the curve in the crossover range. I have to pick up 4 dB in the highs.
