Ha ha! As GPX1200 said, its an addiction. Some call it a sickness. All the same.
Sorry to say my friend, and you can deny all you want (which you haven't, yet), you have the sickness, bad. I've seen a few "one and done". That was me. Hah! Between BFM and Dave Green, my wife has had it. Your's will too.
Imagine when I told her "my friend asked me to build them a cab." Did that 3 times. Not going there anymore. Its the current one (I started last year), your crossovers, and that's it for cabs.
Until I get the ply and order parts to change my 12/6 to a 12/6/1 cube with the T3W crossover, all black, and Reliable Hardware metal grill.
