My father asked me what to do with the old B&W DM100 speakers
Because the wood had taken in water, the treble no longer works, filter capacitors are out dated …
So I started to restore the speakers used during the first teenage celebrations!
Bass and medium unit to recycle are very clean
max budget of 100 € per speaker
glued nailed assembly and using better acoustic honeycomb foam
New filters (except original coils)
Box controller! 
Boomers are OK!
Sounds as good as originals
