Tweeter has been shipped very quickly and is working perfectly now. One point to mention is, that it did not fully fit mechanically as replacement as it was announced, had to rework mounting part slightly
Thanks for the review !

New tweeters bought as a replacement for B&W CDM1SE. Willy's fitted them in my existing housings and delivered promptly. Full marks!
Thanks for the review Jonathan!

Great tweeter, replaced some B&W CDM1 tweeters that the ferrofluid has ceased up in and these sound even better I think, not quite as harsh.
Bit tricky to fit as they are slightly different but easy enough with a bit of common sense
Thanks for the review Chris !

Many thanks for the review Philip !
