Dynaudio Confidence C1 broken & Cap question


Last night we sat down to listen to some music. I quickly noticed something was amiss. Sound was tilted toward one side and figured I had a cable or tube issue. After about 20 minutes of swapping cables and tubes and generally getting paranoid that my Pass Labs 350.5 amp was broken I swapped speaker placement and discovered that one of the midrange drivers was dead. That was somewhat of a relief.

Having purchased these used I took the offending speaker apart. After unsoldering the driver from the cross over board I checked the driver with a 9 volt battery and noted no cone movement. The wires are still secure but something is definitely wrong here. I called Dynaudio this morning and got the impression that because I don't have a receipt, other than AG, they are not going to help me. I'm waiting to hear from tech support. Anyone have any experience with used, broken, expensive equipment and refused support?

If in fact they do and I don't end up with a mono system, I was wondering about the Solen caps on the x-over and a possible upgrade to platinums. Any thoughts on this?

Not familiar with Dynaudio warranty policy specifically, but you generally need a receipt, registration or some dated proof of purchase to obtain service under warranty from any vendor.

If not under warranty, or dated proof of purchase is not available, then I'm sure you can still receive service, which in this case probably means a replacement driver or shipping of speakers to a service center, but you would have to pay.

Or, if you think the speakers had the issue when you acquired them used, you might take it up with the seller to determine if warranty can be established or some form of compensation if the condition was not as advertised.
Prior seller/owner should be able to help yo with your situation by getting warranty work under his name and copy of receipt. For the C1 I would expect the mid-bass woofer to be around $800. Worth a shot contacting the prior owner.
I've spoken with the Dynaudio folks who were suprised to here that one of their drivers went down. The gentleman I talked to said it was the first he's known about. Lucky me.

The cost to replace is about $550 dollars. I'm hopeful they'll cut me a deal. I'm shipping the broken driver back to Dynaudio.

The prior owner I'm pretty certain had nothing to do with the problem of this speaker. They played fine for a month..

We sometimes play music pretty loud, especially my wife. I hope this isn't a pattern to continue. I would hate to feel shy turning up the volume on 7K dollar speakers for fear of breakage! That being said I'm wishful for a way to limit the low end excursion on these drivers and allow my JL Audio Fathom F113 to fill in the space below say 40-45Hz. I think this would have a positive effect on the C1's and perhaps ease my fears of broken drivers.
The most common cause of blowing out speaker drivers is clipping from an amp being overdriven.

I don't know what amp you use, but offloading the low end to a good sub like that sounds like the right thing to do.

Also, if the large excursions are due to rumble during vinyl playback, you might want to look into getting a handle on reducing that because that drains power from the amp in order to reproduce noise, not music. For digital and other sources, rumble should not be a problem.
I purchased a pair of C1s here and shortly their after found one of the bass drivers had a problem at certain frequencies. I was using a set up disc to dial in a sub and the issue was immediately evident. I spoke to my local dealer that I have done a fair amount of business with and they ordered me a matching pair of bass drivers. I replaced them and they worked perfectly until I sold them. I am sure the most any Dynaudio dealer will be happy to help. Good luck, Jerry
