OK, my carpenter has finished today his part, go his final check and the project is officially over for him. Some minor things I will ask him to correct next week. Also I will ask him to put a narrow slightly darker border between horn and the wall, to make it as but more distinctive. We will try next week a few version and I am sure will come with something sensible. Generally I do like how the horns look like, well, it will be better. I would need to find better looking air vents, not the temp crap that we put it. The sound is a different story….
What we removed the plugs and heard the horns for a first time I did expected as triumph. Instead it was a disaster. It is was not bad sound but the sound that clearly indicated that something is very wrong: supper compressed, complete absent of LF, huge HF extension. The whole horn sounds like a bad MD driver. I took a meter and measured the resonance frequency- it was like I never seen before - it has no resonance. I mean the driver from 14Hz to 150HZ gas absolutely linear impedance as it has no active load. I look at all of it and felt so tiered and I walked out if it. I think in the new room the horn is shooting into the wide open sealing and see no reflection and all my back chamber calculation and testing the worked so great for horns in basemen is absolutely not applicable now. I need to redo my entire tests with the horns shooting preaty much in open air… Now today however…
