Hi!
Does anyone know from where I can find specs with freqency response curve for Dynaudio D-52 softdome midrange driver?
I have found some specs for D-52AF but nothing for D-52. 😕

Those drivers are identical, I used to have papers on both and there was no differense, only the "AF". BTW, I`m looking straight at a pair of them right now...🙄
actually D-52 is 3db more sensitive than d-52af I got some specs from italy, now I have almost all specs for both, only curves is missing.
Don`t let any Italian fool you, these drivers are identical and there`s absolutely no 3db-loss made by adding oil to the magnet-gap. They booth are 91db-drivers, though the D-54 gives 94db.
well, I have madisound's pricelist from year 97 therein is following details"d-52AF 89db, D-54 96db and D-54af 91db" and then I have Dynaudio's original specs for D-52, it says 92db sensitivity for D-52. I think D-52 and D-52AF is same driver, but the flange is diffrent, and that makes diffrent sensitivities.
I'm very disappointed to dynaudio regarding their policy to help DIYers. I understand if they don't wanna sell to DIYers their brilliant drivers anymore, But I don't understant why they took all specs away from their wwwsites, and they don't reply for any Emails regarding those specs, why??? I just want to have frequency response curves for D-54 and D-52 midrange drivers, other specs I have already.
I broke one of my D-54 and I didn't get a new one, but I got D-52, Now I have to modify my filter, And it is quite difficult without curves.

I threw it away
I thought nobody can repair it. I was movin away and I had one cupboard where I had all kind of useless things, and this broken D-54 was in there. I thought I won't take this kind of trash with me to new place, and then I threw all away. After that I heard that here in finland is one company who repair drivers, too late for me 🙁 .
BTW I ruined it with too small amp, as usual story is.

Now that explains the confusion! Those D-52`s are real oldies, the design was changed sometime in the eighties..🙄
YEP! completeness is Hi peerless ko10dt (DT 115), mid d-54 /D-52 low Coral 12-L 60. Quite old but I like very much sound of those speakers.
What? 12L-60?? I`ve got a pair of 12L-70 that I`ve saved for a later project, really good drivers but I`m trying to find they`r data..😕
By the way, I`ve allso got a pair of Scanspeak SD-9700 somewhere, still unpacked. They would improve your top..

Yep, 12L-60 woofer which weight is almost 9kg's each, with big box about 200L wented with two tubes it goes easily to 35hz -2db. If you need I can put exact box and tube measurement in here tomorrow.
I'm not sure about Scanspeak SD-9700, ko10dt is quite fine tweeter
inner Measurements of my speakerbox is 35cm x 38cm x 82cm minus tubes and drivers makes appx 100L, yesterday I recalled wrong, I did remember 200L each but it was in total. Length of Tubes (2 pcs/speaker) are 10cm each and diameter is 7 cm each.
Is this 12l-60 similar at all than 70? (see attahed file)
I put in pic freq resp curve also, but it doesn't say much about pure driver.

Sexy speakers those old Corals! The 12L-70`s are using the same chassie and I think membran too, but the foam-suspension is a bit bigger and the magnet-system smaller, more ordinary if still big. That gives a 22hz fs and about 150w cont. power.
Yours fast sounding?

Oh, I was trying to ask if you`re Coral-driver gives a clean, "fast" bass or if it`s more big..😕
