Hi folks.

What I just did with my T-AMP, which is running my mids/highs only:

I just replaced the Input-Coupling Cap of the AMP to 0,05uf instead of 2,7uF on a 20k Input giving me an fg of 160Hz if I calculated it right..

No extra phase shift - no extra parts!
You can use much smaller, crispier and much cheaper high-quality caps.

I used Blackgate non polar in Super-E (had them around - usually use them for bypassing stuff - never thought of using it as coupling cap) .
I've thrown out a Mundorf Silver/Gold for now.
The differnce is not that obvious. Though I did not change back yet. I'll wait 100hours of break-in.

Just calculate your crossover point by taking the Input Impedance
and your Crossover Frequency -- here we go.

I think this is a great tweak. Your AMP and fullrange driver will love it!

Klaus
