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.

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.

Why not another pair of line arrays then?

Those dyns should not fry under normal use though. They were not new and you do not know the history before you acquired them, right? It's possible they had a problem prior and you just pushed them over. Used equipment can be risky. You can never be totally sure where its been.

Assuming you will repair the Dyns, you might just use the sub to take the load off them if you like it loud. Thats usually a best practice for smaller speakers in any case.
