Hey Thomas, thanks for your input. I'm glad to see you've had success with the P.Audio stuff.>*note in my experience 2370's need less compensation than many

Ohms Decibels Power
===============================
0.0 0dB 100%
2.5 2.4dB 58%
5.0 4.2dB 38%
7.5 5.4dB 27%
10.0 7.0dB 20%
15.0 9.2dB 12%
25.0 12.3dB 5.9%
34.0 14.4dB 3.6%
37.5 15.1dB 3.1%
41.0 15.7dB 2.6%
50.0 17.2dB 1.9%You've told me 33 or .22mF should be fine with this horn/driver combo, is this for the bypass cap? How do I convert mF to uF? Oh yea, what sort of caps should I use? (greencaps, MKT's, electrolics or however you spell it lol).
I just realized I dont know how to pick what resistor to use from the chart above lol. Although wayne said a 25 or 50ohm in most cases should work well. How can I determine from the above what is needed?
Thanks! Adrian
