I got the horns today! Thanx again bro!
I took my compressor i got in my garage and put 60 psi in it , and just stuck the 1/8" blow gun attachment to the hose on one horn (longest) and just squeezed a little, and wow!
Felt the concrete vibrate and my ear drums scream! I cant imagine these once i get them hooked up 1/2 " hose - 3/8" manifold to horns…
