Hi all.
Can someone varify my maths here...(it's been a while)
I wish to provide about 7dB attenuation for a horn tweeter. (8 ohms) using a non-inductive series resistor. (not L pad)
My intention is to increase the overall impedance of the tweeter / attenuation, so as to allow me to use lower value capacitors (therefore cheaper) in the passive crossover which will be 18dB/ Octave.
My calculations are a resistor of about 10 ohms will be required..
Any comments appreciated...

Thanks Godfrey..
The problem you mention is a problem with ALL passive crossovers is it not..?
Usually adressed by impedance EQ circuits etc..?
I guess off the top of my head, an L pad 'might' be less susceptible, as it has a purely resistive load in parallel to the driver..?
