I have almost all the parts for my PI 3 build including the PI 290 horn flares from Wayne and DE 250/ 4012HO drivers which I sourced in Canada from the Eminence/B&C distributer.
I am still gathering up all the hardware and am having trouble finding #10 T nuts. I see that a 1/4 20 Allen head bolt will fit snugly into the bolt head recess on the 290 so could I enlarge the holes and use those? I'm still trying to round up the #10 stuff but HD who normally carries them is sold out.
I'll be starting a build thread soon!
