Cap and L-pad resistor quality is critical even in the cheaper models.

I do not use any L-pad resistors with tweeters. If you need to reduce the tweeter output I drop the caps and move the tweeter up at the transition slope. Do not forget that the EV tweeters are dead over 16kHz and all that I need form then is juts to add ½ octave at the top.

The main problem with ribbons is that they need a steep crossover, which is inherently problematic. The other problem is that they seem to have more non linear distortion than good conventional types. Multitone burst tests show this. It is audible as a sort of shimmery silver sound - especially at high SPL, but for low efficiency systems they work OK. Details and image are good to excellent, but integration is a bitch. Best integration I got was with a simple quasi second order series type, which seemed to lock the drivers together. I was shooting for something that started shallow but increased cutoff below the crossover point, sort of like what was just mentioned.

You nailed down the ribbons perfectly. The only thing that I would add that when ribbons sound I feel that that ribbons have diarrhea nd afraid to make any fast movements. Although I still would like to hear those new HE ribbon drivers.

BTW, if you would like to be really entertained then get this :-)
