I was at Parts Express getting ready to order parts for my 4Pi build and I noticed that they now offer the B&C DE250TN 1" Titanium Compression Driver 8 Ohm.

Wayne, which is the best driver to go with for the 4Pi?
I am guessing you have the 4Pi voiced with the original B&C DE250-8, what would the TN version bring to the table?

Thx,
Tom

All my speakers are designed to use the DE250-8. The titanium version may take more abuse, but it will have worse response due to breakup. The polyimide diaphragm provides better internal damping.

Thanks Wayne!

That is what I thought would be the case.

I have the DE250TN with poly diaphragm. I believe that makes it a standard DE250-8. But I'd like to experiment with making my 4 Pi's sound "brighter". Could I put the titanium diaphragms back in and then adjust the crossover? I'm hoping there's a way to try it out without major surgery. Remove or jumper a resistor?

Maybe a better question to start with would be: would the titanium diaphragm make the horn sound "brighter"?

Any other ideas?

Thanks,

Try installing a capacitor in position C1 and see how you like it. In the past, we used a 0.47uF value in that position to augment the top-octave.
