Actually that aint good at all. It wont sound good either ... not good at all.
The woofer box should have been sealed. Making two holes doesnt do the difference you think it does. That isnt a port ... thats just a stupid hole.
Seal the box and make it smaller!
Make seperate boxes for the mids and tweeters. You aint even gona get a simple stereo effect out of that setup with left and right speakers together!
