I've ordered 4 Eminence bp102 speakers (200 W), and a piezo horn. I'm going to wire them like this http://colomar.com/Shavano/4x12wiring4.gif with an Lpad on the tweeter, but I'm not totally sure where to put it in. I'm trying to figure out how big to make the cabinet. I've tried WinISD, but I don't think I'm doing it right. It's giving me a box that's 46" high. That seems way too big for a 4x10. An ampeg I've looked at is 27x24x18 ported. I'm going to make it with 3/4" ply - birch if I can find it unless others have better ideas. Also - what about baffles - how do they go in? Am I in over my head?!?! Thanks to speddling for pointing me here!
