hi vivek ,

i used a third order with correction and L pad to reduce the spl level and worked fine , but these have a burning time of about 10 hrs or so .

GM,
The tweeter we are talking about is the Vifa D27TG-05-06.

Arasu,
What drivers have you used for your project?

Cheers,
Vivek

OK, since it's a well damped soft dome, it should be a good candidate for near Fs loading.

But why do people say that the XO frequency should be about 2 to 3 octaves above the tweeter resonance frequency.

That is done to give adequate driver protection with low order crossovers.

Anyone know anything about the Scan Speak 2904/6000/01 tweeter? Its flange is very small in diameter so would fit well in a MTM with a higher crossover freq, but I've never heard of anyone using it...
