[QUOTE="Joris Wijgerde, post: 213959, member: 13728"] Finally had a chance to do some decent measurements outside (even though it was a bit windy). Measurements were performed using a UMIK1 taped to a broomstick on a ladder, speaker facing upwards. The mic was placed at about 1m right between the upper woofer and horn) Pretty happy with the result so far, the speaker sounds great. EQ & crossover is all armonia on a Powersoft M50Q, LR24 slopes. (90Hz highpass, crossover between woofers and horn at 550Hz) I'm pretty new to interpreting waterfall (or spectrogram) plots, but as far as I understand the spike around 115Hz illustrates something I was expecting. The cabinet lacks proper bracing on the side panels, hopefully stiffening up the cabinet will reduce decay times and tighten up the lower end of the response. Any tips on how to improve this further are more than welcome! Also, Peter, if you prefer I can move this to a new thread but because it's been rather quiet here I was hoping the discussion can help others. [/QUOTE]
