Ok so it's defiantly to do with the horn cavity! Good thinking peter.As a very rough experiment I tried placing two heavy books into the spare space in the cavity which completely remove the dip at 750hz.We've found the culprit! It seems the gap i've left to squeeze the driver in is the perfect distance to cause reflections at the crossover point!(Green = No book Red = With book)[ATTACH=full]209188[/ATTACH]P.S this is a super rough measurment taken indoors.
