Ohhh aye, I did know that the sound is slightly phased on scoops but I never thought that the high frequencies won't make it through the horn. It makes sense though! I'm determined to learn everything about scoops... Thats the task I've set myself over the past few days since I've been ill just sat on here all day. I have learnt a hell of a lot as well. |

because its around these freq where the sound is directly radiated (more like 90hz actually), rather thn through the horn path.
so you either delay for the high or low freq..

will give you the ms

You can't just guesstimate/measure the horn length and base the delay on the path difference. The combined acoustic and electronic response of each frequency range acts as a bandpass filter with its own phase response. You need to measure the devices under test to determine the delay required. A Behringer measurement mic is cheap and most software can be downloaded as a trial. Measuring will also let you get the best out of a digital crossover by tweaking the frequency response of each frequency range.

wow.. its been a while since i asked this question.. i should have monitored it better..
the reason i asked the question was because i had a gig coming up (just passed this weekend) and wanted to us my scoops with my double 18s... i chickened out and just took 8 double 18s... bass was bananas but scoops or horn type cabinets would have carried farther to my liking....
i'll read the comments and i'll probably be asking a series of question on how to better my system performance in the coming weeks... 3 way vs. 2 way, dual 15s midtop vs single 15s.. etc.
thanks again for everyones comments
