The latest and greatest "Project" speaker from JBL, ...K2. With the 811b horns I stole from Speakerman and another pair of 2226j's, I think I might get this nuts. What the heck, you build'm one board at a time. Hey Wayne, it's just a pair of Pro4's stacked with a horn in the middle, right? No Hay Problema. 250 lbs each. I might need a little help getting'em into the Bumstead, or whatever that hotel in Lima is called.
