Could use help,
I came across a woofer and a tweeter cheap, so I bought them.
The woofer is a Selenium 8pw2, 8 inch, 8 ohm, 70-8000 Hz, 94 dB SPL.
The tweeter is a KSN1036A 3000-40000 Hz SPL, 90 dB
Selenium suggests a .66 cu/ft ported box (3 inch dia x 2 inch lg)
I took a look at (basic piezo x-o) found on a link in this forum.
I guess I could use these cap, and inductor figures for a cross
at 3500 or so. Also had the idea to model it after 1Pi, using just a woofer inductor.
My main question is how to compensate for the difference in the dB SPL between the woofer and tweeter.
Any help is appreciated
Thanks Mike

    • To attenuate the woofer, just use a resistor or L-Pad - Wayne Parham 14:18:38 01/13/03 (2)
