The cost would be too high indeed.

I did some measurements in room with UMIK and REW. The red line is listening position (psychoacoustic smoothing and raw) and the green line is near field top driver (0.5 m distance). I guess it confirms my impression of a non-agressive sound with the treble roll off.

These little boxes are just awesome to try different omnidirectional-like arrangements. I must definitely try also the 4 tweeter Sonab/Carlsson OA style speaker setup (placed around a top firing woofer) with them.

Yours roll off more and faster than mine did as I remember (of course it doesn't appear I saved any of the graphs ). I get the feeling that the unit-to-unit or maybe batch-to-batch repeatability on these isn't strong. The data sheet curve looks different as well.

edit: ah, but I did post them -- Ambience tweeters using small BMR drivers

Today I finally did a quick and dirty test. I placed the ambient speakers to temporary stands. The effect is interesting and the speakers definitely add ambience. Now, without them, the sound seems a bit too dry, it is addictive. I have to play around with the level and also frequency limitations on the ambient speakers. I am really happy with the result.
