Hi All,
Could anyone recommend a sweet & realistic sounding tweeter
that does'nt cost an arm & a leg.
TQ

Madisound sells a 96db Goldwood cone tweeter at 4USD, might be worth a try
Maybe give it a very light coating

Hi All,
Ok I'm looking into building a 2 way speaker crossing
over at about 8K to the tweeter. My Coral 10" full/wide
range speaker spec wise is 94db. Specs says that it'll
go up to 20K which I'm very doubtful. Hence a need to
add a tweeter. Am looking for a good sounding tweeter
to go with the Coral.
Thanks for the advice.

Hi Cal,
Sorry no particular preference but would like to have
one that sound realistic & not hifi. What do you think of
Fostex FT17H or FT96H ?
Thank again Cal

I think either of those would be fine but the FT95 wants a high XO point I see but it sounds like that's what you are looking for. Both are very sensitive so you'll need to pad them a bit. Also, the 94 dB rating of the Coral might be a bit optimistic.

FT17H also wants a high crossover but that's what he wants.
I'd suggest considering Fostex FT7RP. fits budget, sweet sound, mild horn loading (active above 8k) should dovetail nicely with the coral, and isn't so sensitive as to need much padding (93dB).
You might consider searching out a pair of the number of vintage Coral tweeters. They were quite efficient ...

I have 4 small Foster horns
Two in series pr side sound quite sweet, with just a few components
Beats me why it works, but it does
On their own they sound awful
Or maybe just use Faital HF10TX compression driver with a small LeCleach horn

Just saw a nice low price on Fostex FT96 at Madisound, 117USD seems a bargain
Or maybe consider a ribbon or planar

Hi Guys,
Thanks for all the advice. In reality, this is going to be my first
wide range speaker project. I'm notsure as to what frequency
is best to cross over too but from reading the posts here, I seem
to recall that 8k is about right to get above the midrange.
Is this correct guys ?
Many thanks

Hi,
why pad down an overly sensitive super tweeter?
Add an extra channel of dedicated HF amplification and drive the super tweeter direct from a Lower powered ClassA amplifier.
An adjustment for gain built into the line feeding the HF amp allows one to dial in the correct sounding treble response.

Or just crossover higher. One of the sweetest supertweeters i've tried was a T90 XOed somewhere above 60k nominal which brought the level down to just about right to meet the 90 dB level of the FE127 at about 14k.

Xoed at somewhere above 60K ????
Planet 10 would you be kind enough to describe the
overall sound of the T90 pls.

Yes. Some 15 dB more efficient than the FE127, you have to get sufficient reduction in level to get it to the same level at the XO.
If we consider a 14k XO, and want a 90 dB level, and the tweeter is 106 dB, we need to reduce the tweeter level by 16 dB. With a single cap we get 6 dB/octave. If we work backwards, 1 octave (28kHz) gives us 6 dB, 2 octaves (56kHz) gives 12 dB, 3 octaves (112kHz) gives us 18 dB. So we want somewhere between about 60-100kHz nominal XO. From there you have to play and set by ear.
T90 sounds very good. What any tweeter adds to the FE127 is quite subtle, and is best discerned by the tweeter's removal after listening for some time.
