I don't know much about speaker's subcomponents and replacements. I
spoke to a costumer service at Madisound about the possibility of
replacing thetweeters. When I asked him about scanspeak he wasn't
favorable about them. He said: "The D2905/9500 is a classic highend
tweeter. All 1" Scan-Speaktweetershave a metal face plate...so it
would be difficult to modify". Can anyone explain this? Don't all the
tweeterscome with a removable faceplate (kef 107 uses square
faceplate)? Thanks



If your looking for replacements consider the new Scan Speak
D2905-990000 Revelator, this is particularly good as a replacement as
it
has a 130 mm faceplate, and will cover up most if not all old fitting
holes
There priced at two fifty dollars

If you wantHi-end the Scan speak super tweeter [2k- 80khz] R2904-700000.
prices range between four and five hundred depending on where you get
them.
Face plate size is again 104mm

Then we have the Twin Ribbon 100khz super tweeter from Jas Audio at
$1500
each.
and very nice they are too.

Thank you for posting your input. You are suggesting Scan Speak
D2905-990000. But does it have a removable faceplate? Please note
that my kefs have an unusual square plate.
However, why would I get a tweeter that goes as hi as 100Hz when the
human hearing is virtually def in those frequencies?

Thanks

You will find that very few if any Tweeters have a removable face
plate, what you will need to do is fabrecate an adapter plate to go
between the speaker cabinet and the inside of the round Tweeter face
plate.
And don't change one Tweeter change both, and modify the crossover to
suit the spec's of the new tweeters.
It really is not as simple as removeing 4 screws, and replaceing the
unit.. Well it is , if you have no idea about how they should perform.
As to the Vifa 25 dollar specials, Sure they will work, It's a bit
like sticking a VW donk in a Murcialago, [Or as TW said about the fual
injection] we know it will work, but performance is another thing
entirly .

As to the question about 100Hz rated tweeters, [ the scan speak 700000
are rated at 80 Hz ] you really have to hear the things to
understand. Again, if you want good performance, you will have to pay
for it.

Will Kef supply a PAIR of new tweeters, to suit there cabinets, and
strange as it might seem, have you tested them, disconnected from the
crossover, your speaker fault could well be a crossover componant,, It
does happen,, but i don't have any idea about the crossovers in the Kef,
it could be a complex unit, or simply just a "cap'' in the line.
