SPL and speaker placement

Kinda surprised nobody said anything about this yet. How about using an analyzer with the mic in the same area as your listening position? Then while moving your speakers to various positions you can see in data form if it's an improvement or not. I'm using a 25 year old (or older) H.H.Scott 830z and the thing is still working just as well as the day it was built. I bought it from a stereo store I used to work for that had it's own unlicensed low power (yea, right!) FM radio station. It only played music with the occasional ID announcement every 45min. or so on a Pioneer CT-9R reel-to-reel, or was that a 909? (Sorry, cd players were still too expensive back then). It was so we could demo equipment without the interruption of commercials. Sure wish I could have gotten my hands on the Soundcraftsmen eq that was in there. Getting back to the analyzer. It could be just as effective to use one of those hand held battery operated jobs from Radio Shack. Food for thought.

O.K. so I'm a little miffed right now but it'll pass. I did an impromptu resonance test on the cabs yesterday by pounding my fist on the top. It rattled!! The sound was coming from inside the cab. It sounded as if the midrange driver was bouncing on the support shelf. Opened it up and it was. Cut out a small piece of peel-n-stick felt and put it on the offending contact area. Problem solved. Went to do likewise to the other speak and got a big surprise. It had the same problem.....plus one. The midrange horn was cross-threaded!! Put on the felt as before and carefully removed the horn, re-wrapped the threads with Teflon tape and reassembled the whole thing. Sure hope that's all that's wrong with these things. But they sound good and getting better. Only 92 hours to go on the break-in-period!
