Dynaudio D-52

Jere · 21st October 2002, 02:13 PM

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.

ask dynaudio they might have the specs in their archinves.

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`ve used both D-52 and D-52AF so I guess that makes me pretty sure.

In what way did you ruin that D-54? If it`s not too badly damaged I might be able to repair it. Another possibility is to put D-54 magnets on D-52 fronts.

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.
