I fairly recently, purchased a used pair of Lii Audio F-12's, from here on the classifieds. Randy chimed in with a comment about the sale, saying how much he liked them - that was all I needed to try them - and the price was so low, I could not pass it up.
I made my open baffles, with the top and bottom separate, so that I could easily swap out the full-rangers on top.
Ever since Steve scaled up Randy's baffles, and used the F-15 years ago, I wanted to try them. But instead, at the time, I got the new addition Crystal 10's, and went from there. But in the back of my mind, I never stopped thinking about Steve's description of the "old school" HIT of the F-15.
I got the 12's instead, because the 15's are just a bit too large for my setup.
I have three different full-rangers now - Wild Burro Audio 8" Alnico, Lii Audio Platinum 10, and the newly added Lii F-12.
All three of these have their own distinct wonderful sound - and all very different from one another.
The big surprise though, is how much I love the F-12. They are just so versatile, and seem to sound great, no matter what I play. I think that I can hear some of the "HIT", that Steve described, but still with the finesse to sound smooth.
Like I said above, my baffles are designed to swap out full-rangers, but these will stay in for a while. I am getting so much pleasure every time I listen to them.
