Lost one of my polydomes on my Kappa 8 recently. Within a matter of weeks it just started to crack and fall apart. The other polydome in the other speaker still looks and sounds fine so I sent the bad one off to Millersound for repair. I am VERY HAPPY with the results. Looks good but more importantly it sounds great. In doing A/B tests of just the top end of the speaker (no woofers) I can't tell any difference playing a number of different genres of music. This is a relief to me because I also own a set of Kappa 9's and have always been worried as to what I would do if/when the polydomes go. Well, that is no longer a worry now that I know there is a good remedy for a polydome repair.
