They have now been used in 3 different applications - a function centre ball room on top of a single 21 inch sub, outside with your typical rock band, and a school for speeches and choirs reinforcement for about 700 people. They worked exactly as I had hoped. They are loud, clear, smooth with no harshness. They threw forever maintaining excellent tonal balance at a great distance.The double 12” W style mid seems to work perfectly up to 800Hz as does the BMS 4594 for the rest of the spectrum.A double 18 inch “no compromise” sub will not keep up with the DIY mid high.I loaned them to a friend who used them for a small charity even to raise some money for the people affected by the recent bushfires. Five bands over the afternoon with very ordinary stage setup but a cost effective solution that maximized the donation $$. In general people were amazed that so much sound could come out of such small speakers; it just didn’t look right. “Wow that’s amazing, so clear” was the typical comment.More or less no EQ was needed other than 3 dB at 100Hz. I did however adjust some of my original settings before the show started. I will measure what I changed and try to polish things a little more.In the meantime the Eighteen Sound XT1464 horns have arrived. I have done some quick comparisons to the RCF HF950. They behave slightly better and are about 2dB more efficient below 2 KHz. Even though the XT1464 was slightly better, given what you need to do to get a 1.4 inch throat horn of this size to provided 90 degree coverage, the RCF are excellent.When I get an opportunity I will sketch up the design of this prototype.</blockquote>
