Fixed it tho.
Making an outboard XO for my garage set to add in a decent woofer. Did some quick and dirty figuring and went to the parts boxes to get stuff.
Found some nice 10uF Vistaon caps in a box of donated parts and thought to myself "Bewdy mate, no need to drive to town and spend $20-"
Soldered everything up and put everything together and the sound was awful. Distorted and strained and painfully loud at the XO frequency and out of sinc.
Anyway in conversation with the part donor it turns out that the caps were NOT 10uF; but 100uF.
Went into town and spent the $20- and it sounds a lot better now. Thanx Peter.
Just one of those mistakes that are easier to make when your eyesight starts to go wonky at close distances, need new a new magnifying glass I guess.
If anybody is interested it is about 400Hz, 21uF & 4.2mH aircore to the mid box and 5.6mH to the woofer with 10uF and a 15R resister to ground.
Designed with the help of Woofer Box and Circuit designer 6.
Plugged the other cap value into the program and it showed as a huge peak and dip in response and an octave overlap too.
