nice one marco... about 10 years ago a pair of 66's were in the local secondhand shop... i scoffed at them... wish i hadn't.. they where about £60 if i remember correctly
it's suprising how good alot of the old kit sounds,
and old speakers do well
in the last few weeks i been having a good mess with some of my collection, the one that suprised the most so far are a pair of b&w dm1's, not with the emi drivers, a 6" ish bass driver and a couple of tweeters.. really nice for a small speaker i too have a pair of celestion ditton 15 but not the xr version same tweeter as the b& w's... i'll have to give them a try...
they all sound well and quite loud with a just a couple of watts.
i also got a single pye corner speaker a few weeks ago, its very tannoy sounding
cheers

DM1's with a 6" or so round bass unit? That is interesting, any chance of photos? I thought all DM1's had EMI elliptical.
If your still looking at recapping these 66's look up 'celestion ditton 66 needs midrange' on diyaudio all the information's there including crossover schematics etc, i followed these guides to redo some ditton 44's, they now sound even better.

a couple of pics attached.. i would guess these are later versions ?
they sound very nice... modern sounding sort of bright and sparkly with the valve amp
i was very pleased with the sound, they have a nice bass balance, not boomy... just right for a small speaker..

Hi SPS, thanks for the pics, I strongly suspect that someone has converted these DM1s, using a new front baffle a replacement bass unit. I have thought of doing this myself as one of my DM1's has a faulty elliptical bass unit. I have three pairs of DM1's.
If you ever open up the cabinets, I would be interested to know what the bass units look like and what markings are on them.

Hi Chris,
That's very interesting. However, you need to be a member of DIY Audio to use the search facility, and I'm not, so could you please post a link here to that discussion?
Cheers!

you clever fella...
front off... they have been re done...
my camera is crap...
the bass driver says on it 17-fgwb made 3.81 made in norway
tweeter i would guess is celestion... T1295
the small tweeter just says tu (could be vu) 29a
the pictures show the rest... thanks for the info...
i have a few emi's spare? not sure if they fit the dm1
where the two tweeters original and the just the bas verion of the emi, i would also guess its not the 13x8 ones i have.
cheers

Your tweeter's and crossover look original, tweeters: Celestion HF1300 and Coles 4001G, exactly the same as in DM4, DM2, Spendor BC1 etc. Your crossover is the later one as it has the mod to reduce slightly the output of the 1300 tweeter.
The original DM1 bass units were EMI 10"x 6" with a special fibreglass laminated cone, similar in construction to the 13"x8"
Your bass units may be VIFA / Seas, usually good units
Heres the link, i recommend that you join i think its free, just so you can follow the diagrams, theres also recomendations for capacitors/resistors to use.
