Rated 5 out of 5 by from B&W CC6 ReplacementBought to replace tweeter in B&W CC6 that is no longer available. Perfect fit in face plate. Had to change one terminal end. In my opinion, sounds great. Maybe a tadbrighter than original. Understand that it will "break-in'. Cheap save for an expensive speaker.

Rated 5 out of 5 by from another B&W replacementI too used these Vifa tweeters to replace tired tweeters in a pair of B&W P4 speakers. The ferrofluid in older B&W 1" tweeters has a tendency to dry out and they start sounding flat and lifeless. These Vifa's popped right into the hole, only had to change one of the wire terminals on each side. In ten minutes they were both changed. My P4's now sound great again. I'm now looking for a period B&W center channel speaker to complete my setup. I will replace the tweeter in that too so the whole front stage matches.

Rated 5 out of 5 by from The size and performance is hard to beatWas looking a 1" tweeter that would exactly fit in to the Polk speaker housing faceplate on the RTi 8's. Just glued them in place after cleaning up the channel and WOLA! Enjoyable from the get go and balanced in every way without any harshness. For an old school audiophile who's hard to please, that's saying something.

Rated 5 out of 5 by from Great replacement for Infinity RS3Sounds like the original and was easy to install. All I needed to do was flip over the mount to hold the tweeter on because there is a surrounding peice that prevents it from going all the way in. Check out the pictures it looks great.

Rated 5 out of 5 by from Another Satisfied B&W OwnerI had an old B&W CC6 S2 center channel shipped to me that only sort of made it. (Thanks, UPS.) Busted Tweeter, broken crossover mounts, loose internals... a mess. Rather than go through the hassle of claiming insurance and not being made whole, I decided to try parts express fort the first time based on the review below from another B&W owner. I needed a compatible tweeter to fit in the space that would blend well sonically, but not cost me $132 and only sort of fit. (No exact replacement manufactured, any longer.)The Tweeter:Its very good. When you consider it was $115.00 cheaper than what its replacing, it becomes outstanding. As the other B&W owner noted, this has a somewhat edgy tone out of the box. I wouldnt quite call it harsh, but Im looking forward to this break in peroiod being over so I can enjoy this little gem's fuller potential. I can attest that my ears are noting it becoming more balanced and rounded as it continues to play.Also, its worth noting- I found the tweeter's output seemed a little hotter than the B&W stock tweeter, as well. So, if you are considering this for a B&W replacement- I agree that its louder. I used a little EQ in my receiver and Voila! An Lpad is a more correct solution, but I like the forward mid-highs in my center. I think I'll keep it as is.Installation was a cinch. This guy it pretty thin. So, I shaved the plastic wings on the edges with a razor and pressed it into the cabinet's plastic housing for the tweeter. It aint going anywhere. Perfect. A little sauldering for the connections (optional) and you're all set.I can't say thank you enough to the previous B&W owner/reviewer, and I concur with everything he has said in the previous review concerning the tweeter's buld and sonic qualities. A final note, I happen to have a pair of P4's myself. I love them, but I had to replace the tweeters long ago with a product that's never been very good. I like the sound from the Vifa enough to order another two to get a matching set for my center. And of course, they are coming Parts Express. Very Satisfied first time customer.

what is the difference between the  0C25SC05-04 and this model. I am trying to locate the correct tweeter for my speakers

Asked by: Mercuryxr2
The only difference I can see are slight variances in Fs. Otherwise these should be virtually identical, and interchangeable.

I have a set of B&W 602 s1 which have a dented tweeter which no longer functions. I contacted B&W and it sounds like each tweeter costs $100 to replace which is more than I would consider spending on these. would these be an almost suitable replacement?

Asked by: Voyaja
We always recommend replacing tweeters like this with the original. This tweeter may work as long as the impedance is the same, but it will sound different than the other speaker, so replacing both is your best bet. You will probably have to modify the enclosure in order to get this mounted properly since the original is proprietary.

hi will this fit the CC6 S2 B&W centre speaker? Thanks A

Asked by: Aidan
Unfortunately this will not be a direct replacement for that tweeter. You would be farther ahead contacting B&W for a replacement since their drivers are all proprietary.

Does this come in an 8 ohm version? OC25SC65-08 ?

I have disassembled mission 731 (not i) to replace burned out tweeters. The tweeter mounts from the rear with a twist lock ring to the baffle. This tweeter has the exact diameter that would snap in, however the 731 is an 8 ohm speaker. Thank you.
Asked by: JBF2
When used in a full range speaker system with crossover the tweeer impedance at4 or 8 ohms would make very little difference.ale sure to replace both boxes tweeters so the load ( even though minimal difference) would be the same.
