realworld experience: Kharma subwoofer + 3.2 CRM


Beyond the shows and the recent positive comments by Jon Valin in the latest Absolute Sound, does anyone own the Kharma subwoofer and 3.2 CRM combination. If so, would they like to share their experience. What about playing this combination fairly loud (e.g. alternative rock/rock) ? How does the combo compare to say the Grand Midi's ?

Tim,

Do they really break that often ??? Are both the 7" and the 4.5" prone to this ? How much is a new midrange driver ?
Replace with new mid without changing the x-over?
How come? Aren't the new mids 2db more sensitive than the old one ?

Tpsonic,I agree with Tim as long as you know soldering.
I know the drivers have a year waranty from time of purchase, so if you buy new you have some added insurance. I can not say if people continue to have problems but I know of at least 4 people off the top of my head who have had 7" ceramic mids either crack or completely blow apart.
Tireguy, any idea why that has happened? Are the ceramic cones really that fragile? Perhaps some residual stresses that eventually manifest themselves?

The Kharma websites says they have a 5 year warranty for the original purchaser. From Tireguy's description it sounds like there is a serious issue with the ceramic driver. Could people who have experienced this driver failure please comment?
