jwc Posted October 21, 2017 Author Share Posted October 21, 2017 I'm sure he has had a laugh out of me many times. I just want to tighten the woofer screws from the inside and make sure the driver is flush. Quote Link to comment Share on other sites More sharing options...
mark1101 Posted October 21, 2017 Share Posted October 21, 2017 Looks like the rod is threaded and the retaining nut is holding the cover on. You may be able to grab with vise grips and loosen to help loosening the retaining nut sitting on the cover. Looks like at least the retaining nut and maybe the rod has to come out get the cover off. Maybe a drop of wd-40 on the threads where the retaining but sits. Guessing. Quote Link to comment Share on other sites More sharing options...
jwc Posted October 21, 2017 Author Share Posted October 21, 2017 That Center nut does come loose but doesn't come all the way off the pole. Once I do that the pole gets loose and wiggles. The four screws are taken out of the lid and it does not budge. I'm just assuming it's stuck. Quote Link to comment Share on other sites More sharing options...
Marvel Posted October 21, 2017 Share Posted October 21, 2017 I'm guessing you are no longer interested in the MWMs. No progress on getting them loose yet. Those KP600s look nice in the room. More WAF than a pair of Avantegarde speakers. Bruce Quote Link to comment Share on other sites More sharing options...

twistedcrankcammer Posted October 26, 2017 Share Posted October 26, 2017 Hey JC! Did you call Kev?? I had mine apart before to recone that 10 inch, but just6 don't remember any more for sure. I do remember it coming apart real easily though. You could ask Kev to ask Roy as well if he does not remember Rog Quote Link to comment Share on other sites More sharing options...
twistedcrankcammer Posted October 26, 2017 Share Posted October 26, 2017 JC, If I do remember correctly, I think all you have to do is remove the 4 that go through the perimeter of the wood. Then you have to brake the seal as there is like a rubber / tar weather strip around the perimeter bottom of that fiberglass and plywood. I believe the re-rod is just nutted on the other side of the plywood, and the other 4 screws are what ho;lds that 10 inch woofer in place. So if those 4 screws towards the horn are tight, your driver is tight. No real reason to take it apart unless blown or you have a voice coil rubbing!

jwc Posted October 28, 2017 Author Share Posted October 28, 2017 Yea I still have them packed away somewhere. I haven't fully decided to sell them yet. I may now need them as back up....let me think on it. Quote Link to comment Share on other sites More sharing options...
jwc Posted October 28, 2017 Author Share Posted October 28, 2017 I was able to pull a lid off one of the MB unit. The applied gasket is sticky. I actually have to use a small flat head screw driver and a hammer to slightly tap through the lid holes to jar loose. I do not tap on the fiberglass. So as I figured...the center pole doesn't come out. Just leave it there. I have a few of the MB modules that are bugging me because it appears the woofer isn't mounted exactly straight. Probably not enough to matter..... The one here I had to loosen the woofer inside to slightly to straighten....and it still wasn't right. I therefore removed the woofer, filed the holes in the fiberglass a little to allow the woofer to mount more center line. Looks way better but could be more perfect. There is a couple that will have to be addressed. All this stuff is in great condition for being 30 years old. I applied a new gasket/foam. The gasket on the woofer looks like new as well as the woofer/driver. jc Quote Link to comment Share on other sites More sharing options...

Wanted to look inside the Midbass Horn Module to check for correct driver and tighten down the woofer screws. However, I have to get in to the "capsule" (lol) to get access to the 4 woofer screws inside. I can't get this lid off. That middle bolt on the post only screws to loosen slightly. I don't know what is on the other side. I Can take the 4 screws off the lid....and this lid doesn't budge. Any suggestions? Just take out the 4 bolts and the post comes off with the lid. You can then go inside and remove 4 more more nuts and bolts that hold the driver in place and pull the driver. I just finished doing that yesterday.

Difficult to do without damaging the fiberglass. The gasket is really stuck on some of these. Quote Link to comment Share on other sites More sharing options...

Moderators Travis In Austin Posted January 12, 2019 Moderators Share Posted January 12, 2019 Hey, by coincidence, somebody left a KP-600 system outside the Museum Steam Generating Plant Museum building out at the airport with a note that said: "We just don't have the room for these darlings any longer and we heard you will give them a good home where they will be loved and appreciated. They love to be flown and played loud." They were brought inside out of the cold and rain. They will indeed get a great home! 4 Quote Link to comment Share on other sites More sharing options...

Moderators dtel Posted January 12, 2019 Moderators Share Posted January 12, 2019 It was a very nice thing to do, and thanks to the moving guy. Thanks to both of you, it's a very nice thing to do for the museum, and the history, to make sure a copy is saved. Thank you JC 1 Quote Link to comment Share on other sites More sharing options...
