Hi I am making progress on the CAD version of the 90 degree box. The two prototypes have already been out on festival duty and have performed brilliantly. The next step is putting the CAD prototype together which is proving to be quite a task. I have gone for a laminate curve for the horn flare instead of cutting a few different angles. Also decided to use high density foam for the curves to try and cut down on weight. I will be testing the curved flare at our friendly university anechoic chamber when I have fitted the drivers. The original prototypes are processed with Lake LM26 and we managed to get the FR nice and flat from about 80Hz up to 16000 or there about plus or minus 2dB. Initial thoughts live were that the sound is very clean with small changes to system eq being instantly noticeable. Running them with 4, 18 inch subs a side we were registering high SPL,s at front of stage 112dB with average levels at FOH of between 95/105 I will post results as soon as I have some. I did E-Mail Peter about two weeks ago with a progress report have not heard back as of yet but my mail may have been trashed.
