[QUOTE="gbyleveldt, post: 55533, member: 122"] Ian, do an impedance sweep of that tweeter, undamped and mounted in the WG, and check it's resonant Freq. It really does sound like the WG has shifted the Fr of that tweet and this may very well be close enough to the XO point of the HP filter to change it's response. That may explain the low Q? Just taking a flyer here and still very rusty. It may very well explain why you didn't have an issue with the DCX, as the impedance of the tweet will affect a passive XO but will have no effect on the low output impedance of an amplifier connected directly to it.
