[QUOTE="JimGore, post: 69154, member: 3"] I am a bit worried about making those ports, simply because the pipe size isn't standard - ie it cannot be purchased from a hardware store. I am thinking of making one from scratch to accept the more standard PVC pipes. Will keep you posted on that one. The XO is simple second order for the mid/bass @ 2500Hz. It includes baffle step compensation. Coil: 2.6mH (large because of the BSC) Cap: 6.8uF Tweeter: The XO point is a bit of a strange one - first order @ 20kHz (yes, 20,000Hz) This takes care of the bump in response caused by the horn, and together with the natural roll-off of the tweeter gives an effective crossover point of 2.5kHz with a reasonably flat response. It's a good thing I have SE to do simulations with - this is seriously not textbook stuff ;D Series resistor: 8.2ohm (padding to bring the level inline with the mid/bass) Cap: 1 uF Regards, Ian.
