Here's the crossover schematic for the B&W DM2 version II speaker.
Hope it helps.
Thanks for that, I will use it to try and understand the different crossover in my DM2s and to renew the capacitors which I should be able to find on the Falcon Acoustics site.
There is an even earlier version of the DM2s than the images you have posted. It used some unidentifiable Super-tweeter (not the Coles 4001) and the Mid/High unit and the Super-tweeter were place side-by-side. The crossover didn't have the adjustment control that appeared on the later version. I have no idea whether the crossovers were identical apart from the control - I will eventually work that out.
This LINK shows my early version of the B&W DM2 with the Mid/High frequency HF1300 & the unidentified Super-tweeter side-by side below the DW200 bass unit.
This LINK shows the second version, with a Coles 4001 and all three speaker units in line vertically.
This LINK shows the first (white, lamb's wool?) and last (grey) layers of wadding.
This LINK shows the first and intermediate (carpet underlay like) layers of wadding.
This LINK shows the last, coarse and stiff layer of wadding which sadly is now turning to powder.
The cabinets on the later versions I own are VERY beaten about. Rather than trying to refurbish the cabinets, I may try to make an exact (but undamaged) copy. I don't understand the three different types of wadding used or know what I could use to replace the final section nearest the port opening. B&W can't offer me any help.
I have read somewhere that the B&W DM200 bass unit has characteristics very similar to the 8" bextrene coned Kef B1039 but have no idea whether or not that is true?
