VanArn Posted July 19, 2023 Posted July 19, 2023 (edited) I am mistaken about the 800401 version. It is not a coated paper cone model, that was the earlier 22W-75. PHA is the name that Dynaudio used for the polymer cone before developing the one piece polypropylene cone for the 24W-75X. The 24W series are basically 8'' speakers , on 9'' frames. Why have you not considered having the faulty speaker repaired? Edited July 19, 2023 by VanArn

Or you could wait for the same pair to come up. That could take forever. A totally original pair of those Duntechs is gonna be a rare thing as the surrounds have gone on most of the woofers these days. Also the mids are not that durable either. So originality would be optimal but hard to find these days Regarding the Sovereigns you’re gonna need a HUGE room and very good amplification. The Princess are much more forgiving regarding room size and amplification. A lot of people that I’ve spoken to that have had both have preferred the Princess. Yes I have had my eyes on the market for some time now; Dynaudio 24w75 are hard to find, it would probably be easier to source genuine dilithum crystals from the Klingon prison world of Rura Penthe. To be honest I am not planning to sell the Princess's, after all I have wanted a pair for almost 30years, so my point was that I have a strong desire to keep them true/real and would always want to do a hand on heart sale good faith to the next person. I haven't got an amp yet Been waiting for the ME1200 Edited July 19, 2023 by sockpuppy 1

Why have you not considered having the faulty speaker repaired? I tried , sent all 4 to Brisbane speaker repairs for refoaming. The back story is that I purchased the Princess's pair with a known broken seized driver. The seized driver driver coil didn't come out and ripped during extraction, I wasn't surprise it was unrepairable. Edited July 19, 2023 by sockpuppy 1 1

You could always sell the X pair then or keep for spares.

sockpuppy Posted July 19, 2023 Posted July 19, 2023 (edited) It does actually look like the XL where used at Duntech. Am I wrong in thinking the Crown Prince and Princess are analogous? Although it is model 87385 vs 87361, this is really doing my head in. This is interesting is anyone here dxtimages from https://www.diyaudio.com/community/threads/duntech-crown-prince-dynaudio-woofer-replacement.371178/post-6627969 So looks like the 24 w XL 8 Ohm was used in crown price Edited July 19, 2023 by sockpuppy
Xylotuol Posted July 19, 2023 Posted July 19, 2023 hello, I have a proposal to remanufacture the duntech logo for 50 euros each. Does this interest anyone? the price should be reduced if we order more than 2 The problem is I'm in Europe (France)... Tell me Regards Xylotuol

sockpuppy Posted July 20, 2023 Posted July 20, 2023 (edited) Disappointingly, after getting my drivers back, plugging them in, I tested the Princess. with an old Rotel Amp. All three drivers were working, including both tweeters. However, upon closer inspection, it appears that all four Scan-Speak 13M / 8640 drivers are silent. I could have imagined one or, at worst, two not working, but the fact that all four are malfunctioning seems odd—what are the odds of that happening? Could this issue be related to the crossover? What to do next? Crossovers look OK, cannot see anything physically wrong with the capacitors The only thing a little funky is the a few of the resistors, however I think I am just seeing solder flux rather than a problem Edited July 20, 2023 by sockpuppy
VanArn Posted July 20, 2023 Posted July 20, 2023 There are many instances of ScanSpeak drivers going open circuit as a result of electrolysis at the connection of the flexible braid to the voice coil lead out wires. The condition is indicated by a dark patch under the adhesive holding the joint to the cone. Delicate repair work is needed as the cone is fragile. 2

Jakeyb77_Redux Posted July 20, 2023 Posted July 20, 2023 @sockpuppy yes the mids are a known problem speaker. This is why I have collected as many spare parts for this model speaker as I can find as they are VERY rare especially in working order. @kelossus is currently searching for some mids as well. While these Duntech speakers are great, unfortunately being so old they have major problems if you have any issues at all due to the unavailability of parts. You may be able to get the mids repaired. I think Atilla’s son Adam has been repairing speakers after his Dad passed away sadly. Search the forums for a contact number he’s in Thomastown

The CP had the sock. And your Princess and mine are different also) and speakers but drivers changed as they saw fit. Some have different iterations of the D28 tweeter also. John Dunlavy loved the Scan Speak mid and I haven’t seen any with a different mid range. The woofers would be all different depending on what was new/available etc I’d say. My woofers are definitely all 6ohm from factory as I checked them all the other day. Yours would have been carefully matched to the crossover so I would try and replace like for like no matter what other people’s speakers came with. But you gotta get what you can find available I suppose. Edited July 20, 2023 by Jakeyb77_Redux
sockpuppy Posted July 20, 2023 Posted July 20, 2023 Anyway want to guess what Ohms these are ? From Dynaudio Recital loudspeakers apparently. They have the felt at the rear that probably pushes them to the 24W75 XL type. https://www.ebay.com.au/itm/185938236637?mkevt=1&mkcid=1&mkrid=705-53470-19255-0&campid=5338381868&toolid=10001&customid=ef4dcf58-26d9-11ee-8d73-636437633039

I’d be keen to try them if they were very close.
