let's see what's inside...

well, I guess i never mentioned what the speakers are, that might be useful, each side has an array of 10 dvdosc elements. they are wired in 3's with the top on it's own amp. but I think I want to change it so that it's 2,2,3,3. that way I can adjust the top 2 (the only ones throwing all the way t the back) and add a little more HF, it sounds a little dull in the top of the terrace when I was up there the other day.
anyways, I opened up each speaker, pulled out the horn cleaned them all and then ran tone and pink noise through them, i logged the graph of each one with their serial #'s so i can go back every year and see how they are performing... i found one of the mid range drivers was loose, and there was a lot of paint chips and hairs(or threads) inside, but other than that, they were in pretty good shape.

here i am making sure that the amp i am testing with is set to the right max voltage and polarity...


i put the measurement mic touching the ground to eliminate reflections.


lookin' at the screen, having no idea if what i was seeing was proper or not. it all ended up being slightly more of a comparison of all the speakers to each other, not really to what they were necessarily supposed to be. :(


the back panel comes off and then 4 hex screws take the back of the horn off, unfortunately, if you want to put it back together you have to torque it to a specific ft. lb. so i got to buy a $50 screwdriver just for that...


and finally i'm done, with one side, luckily i wrote down their order so it will go back together with no issues.
