They must have bought the tooling from KEF. It looks identical.


** HUH ???

The only *identical* thing is the diameter of the ****ing face plate
!!!!!!!

FYI:

28mm dia VC - not 20mm.

Aluminium VC former - not plastic/paper.

Fabric dome - not polyester.

Any 104mm dia tweeter would do as well.

The differing dB/watt figures are a worry too.

The first thing is considering dB/ watt and system integration.

Watts per mid and woofer ? Tells nothing.

The other thing, you have to know the phase angles of the drivers at
selected active crossover points.

dB per watt isn't actually much of a worry in an active system.

Just attempting to give a rough guide on how much level the tweeter has to
handle. If that didn't matter they'd all be the same.

In spite of everything, that T27 look-alike will do the job nicely.
There is no hard-and-fast rule, because the balance between tweeter
and mid changes hugely depending on the source material. I'm not
picturing you listening to highly compressed techno trance, so you can
get away with something like a five to one minimum. You weren't really
thinking of driving them into limiting either, were you?

I like lots of different sorts of music. But don't much like 'delicate'
speakers. Any idea of the maximum SPL of the 'largest' speaker the T27 was
used in?

BTW are you suggesting you 'voice' a speaker according to what it's going
to be used for? That will be difficult here as they will be used for a
wide variety of things.

Not really. I think speakers should be voiced for fidelity, whatever
the source material. But you might want to beef up the tweeter power
handling of you know there is going to be a lot of screaming top.

One of my main priorities is decent speech quality. Hence modifying these
speakers. The original tweeters are Audax TWO34XO which don't sound as
'sweet' to my ears as either the T27 in the 3/5a, or the HF1300 in the
BC1. Even although it's now only handling things above 3kHz.

Well, speech is just about the hardest source material you will find.
Almost every speaker reveals itself to be boomy under speech. And a
smooth tweeter is absolutely vital.

Then talk driver sensitivity.
