[QUOTE="Norval, post: 784055, member: 62"] Jus a add on to my prior comment. I just re-read your first post, and see you mention x-over at 100Hz and 4ooo Hz. I can with almost 100% certainty say, that was probably what you aimed for, but the actuals are where you have the drop outs, (750 and 4k). I can with the same amount of confidence say the problem is most likely to disappear if you reverse the polarity on the mid. Having said that, you don't want the centre to centre spacing between the mid and tweeter to be more than the wavelength at x-over. At 3500 Hz that is only 100mm. [/QUOTE]
