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 !

Easy fitment to rescue my B&W P4s and they sound great at least to my ears.
Many thanks for the review Philip !

Used this tweeters on many B&W's that i have fixed and restored and they sound just as good as the orginal.
Same signature tho i think they are smoother somehow the OE can be a bit "hash" but this is not a problem with this Soft domes :)
For your B&W P4/5/6 or CDM or even Matrix series, you cant go wrong with this replacement part :)
Thankyou for your review !
