hello Christian, could you post a photo without the stick? if the paper cone is not damaged, you can cut and clean the foam around, and glue a new surround on it, let it drie upside down, you can reallign the spider when you glued the outside of the cone to the inside of the surround, and after that you can try to reallign the speaker untill you don't hear a scraping sound anymore, but just glue diagonally, when it is drie, you do the oppisite , untill you had the whole speaker done. I think i still have pix of a glued- refoamed woofer that i did in the past (think a little bit bigger) I used clothespins and pieces of foam to press the edges against the metal chassis. If you want the pix i can send them, but think they are too big to upload here

Hi Thank you for the helpful hints. For me it looks like the stick has left two dents in the paper cone while it was there for several years and I'm not sure how to bring the cone back to shape, maybe with hot steam. I will take out the speaker next days, foam surrounds are already ordered. I give more information after that. Regards Christian  

Hi In between I dissassembled the 8" and 10" woofers from the cabinet. The coils are measuring all good so far. I decided to bring them back in shape as following: Took some aluminium profiles 10X10 mm and put them underneath the cone to lift the cone upards about 1 cm above the metal frame. Sprayed with a small amount of water front and back of the cone and let them laying cone downwards on the table over night. The weight of the chassis gave the right amount of pressure to the cones and next day it looked very good for me. on the picture you could see the result. Does anybuddy have a good source for the front fabric? Mine have some small holes and not looking good anymore.

Hi Christian - good progress! For the fabric: I used akustikstoff.com (for my 8000s & 6000s) and liked it. Regards, Johan

Hi Yesterday the foam surround from "Good Old HiFi" NL arrived. So I started to refoam the 4 woofers. First I started with the 8" woofer, cleaned the cast frame and carefully sraped the old glue from the plastic cone. My favorite solvent Mellerud glue remover made a good job. Before: Login to view image After: Login to view image After cleaning I glued the foamsurround as much possible centered to the cone. I've made a marking arround the cone to see how far the glue should be painted. Put the glue to the backside of the inner foam let it dry for about 5 minutes and pressed it firmly to the cone. After that I clamped the outer foamring with clothpins to the frame and made a test with a conected amp and my mobilephone and the "Tonegenerator" app at 25 up to 50 Hz to hear if the voicecoil is aligned an centered. No adjustments where requiered. The 8" woofers need no chimming in my case and I glued the foam to the cast frame. You could see on the last picture. Up to the 10" woofer. I started with glueremover very carefully only on the old rotten glue because the cone is made of paper and I would not to get to much moisture into the paper. After about 10 minutes I could peel off the old glue with my fingernail. There is a minimal layer of paper wich comes off with the old glue but that's no problem. As you cn see there is a damage left from the stick wich was mentioned in the first post. The new foam surround covers exactly thes damages so I'm happy. ;-)) Login to view image Next was the same steps as the 8" woofer, I glued the foam to the cone , tested with clothpins and made a marking around the outer foam to know where the foam has to be glued on the frame. Login to view image The cone centered itself like the 8" woofer, no alignement nessesary. Here is the result:   cheers;-)) Login to view image Complete set of woofers after 5 hours: Login to view image Thanks for watching! Next is the renew of the fabric grilles, new capacitors on the filterboard and refreshing the wooden case. Kind regards Christian

Hi, here are some news... I cleaned the wood with a magic eraser and a light soaped water with a neutral soap. Login to view image After letting it dry I put some renovating oil on the wood and let it shine again. Login to view image I recapped the Crossover network with new bipolar caps, just business as usual, old ones out new ones in. Login to view image After that I assembled the chassis into the front frame and made the wireconnections to the speakers. Mounted the frame to the speakers and made a testride. Wow that sounds absolutly amaizing. Here is the not really finished speaker,  fabric was not delivered today  ;-) Login to view image Login to view image    

Well done. Excellent work on these beauties. ?? Superb speakers I’ve been trying to get for ages. I had to do with the lesser MC120-2. Almost there, but not quite !

And how does it sound? :D

As I already wrote, the speakers sounding absoloutely amazing. Far different from the M 150 of course more deep bass. Have the MC 120.2 in another room, did never expect such a good fundamental sound, missing nothing. Next day I hope to compare with my Nubert Nuline 102. It´s not a real comparison ;-) Now it´s time to say goodby to my 5.1 set and switch back to stereo with Beomaster 8000, Beogram 8000, Beocord 9000, Beovox MS150.2 and a MC 40 cabinet. Maybe I connect a pair of CX 100 to the secondary speakeroutlets to have a "rear speaker". Have a nice week Christian
