Quick update on the project -

- Still trying to resolve the issue with UPS. They took the speakers from my house and back to their facility for inspection and returned the speakers after 10 days and sent me a invoice for 51 USD 😭. 

- Meanwhile, after moving parts between the two speakers now I have 1 working speaker.

- I am now looking for two items to restore the 2nd speaker -

       1. 6.8mH coil on the crossover. I looked on the internet and everything available is too heavy and             big. 

        2. 8" mid-range speaker (damaged cone). 

My only hope is this forum. If anyone has any of the above parts, do PM me. 

Thanks !!

Hi

Search for this Scan Speak Midrange Speaker.

Fits nice and has the same specificatioms like original.

Not very cheap but new.

Often the drivercoils come loose from the diaphragma, sometimes, not always the coils are burnt.

So it´s your decision to buy a used one or a new one.

Merry Christmas.

Thanks Chrischi.

The 3" speakers are fine, it's the 8" speaker that's damaged.

But thanks for the info.

Happy holidays !!

I did get some time today to open the second speaker and the crossover PCB. The 6.8mH coil is 40mm x 39.5mm.

So the closest match is - https://www.tme.com/us/en-us/details/fc-6.8mh-vs/audio-coils/visaton/3704/ Ordered and hope to get it in 7-10 days. 

The round trip from UPS after insurance inspection has done some more damage to the crossover PCB. 1 trace was broken rest everything seems to be ok. Am worried about the weight of the 6.8mH  on the board will cause more damage. Will need to figure out a way to secure the pcb.

I pulled out the 8" drivers. When pressing on the cones there is no movement, they both are stiff. The 10" drivers move when pressed on the cone.

Are the 8"  drivers damaged beyond repair ?

Thanks !!

The 6.8mH coil arrived and the size is similar to the original coil. So both the crossover boards are good now. 

UPS was good and approved my claim. So the MS150 speakers are "free" for me now.

Need to replace the surrounds on the 10" woofers and they will be good.

8" - Both of them were frozen. I followed instructions on Sonavors post (/forum/imported-unmapped/a-beovox-ms150-project) and was able free up the voice coils. 

John - Were you able to use the restored 8" drivers ? 

Q - The cones on both of them are damaged. Are there any replacement cones available anywhere ?

No, I only restore the foam surrounds. When it comes to the mechanical parts of the driver I take them to a professional speaker repair shop in Dallas - Freeman-Tuell.  They have been in business for a lot of years and are really good at repairing speaker components. I used them to replace the foam surrounds on some Yamaha NS-2000 woofers I own. The woofer drivers have an unusual size - 33cm (13 inch) driver and I couldn't find a replacement surround for it. Freeman-Tuell made surrounds for it and it works like new again.

Thanks Sonavor, I did call Freeman-Tuell . They said that if the voice coils are frozen then they wont be able to do anything and they were not sure about the cone also. Maybe I will ask them to "try"..worst case I am down by shipping fees.

How about 

No Sonavor. I haven't reached out to them as yet. I will try speaking to them on Monday.
