I have been lurking and learning much from these forums for a while now, but the time has come to post my own question.
My brother and I are building a stereo system with our own custom active crossover network. I have had no prior experience with AC circuits, but I have have done a bit with digital and DC.
Our network consists of 8 filters each with ~100 gain; 1 Low Pass with cutoff at 500Hz, 1 Band Pass 500Hz-3.4kHz, 2 Band Pass 500Hz - 2.5kHz, 2 Band Pass 2.5kHz-15kHz, and 2 Band Pass 15kHz-30kHz.
I constructed these in Multisim 11 and used a Function Generator with a sine wave at 100mVp to test them. I connected the outputs to the oscilloscope to check for signs of clipping.
Everything seems to work well in simulation, but I just tried to realize the low pass circuit with a 4ohm speaker, and I get no audio just a snap; as though I had connected it to a DC source.
As I said, I have had limited electronics experience and certainly nothing like this. You guys seem to be very good, so I hope I can get some help.
