Default Please check this xo for me


I've got four audax HP100mo 4" woofers and 2 Audax TM020J5 tweeter on the way.

here are the links


audax tm020j5

Im trying to work out a starting point for the XO so I can order some parts. Could someone have a look at this and let me know if I've made any major errors.

A couple of points:

I bought these because they were very cheap on sale and I just want to mess around. I know there are drivers with better FR and these may be a bad combo, but Im just doing this as an exercise. If I like the end results thats a bonus. I dont have a measuring mic at the moment so Im just going to experiment and see what happens

I'll add an L-pad later. That, at least, I can get the parts for locally.

The XO below is for a two way and Ill add the second woofer at about 400 hz for baffle step.

I used an online XO calculator and checked against a second one.
Some people here have warned against using them but I dont know why. If any of this looks screwy please let me know.

Well the spacing in my very high tech XO diagram in the post above got reformatted. Its supposed to be a 4th order XO.
