Perfetti! It gets very loud and crisp, lacks mids, but as is the case with DJ/PA 2 way speakers. The picture shows that they have a back. The hardware that came was designed for 4 mounts on the wall, but only 2 grooves were premilled. Unless a wider version becomes available, I wont be ordering these again. Che dire? Che sono ottime e consigliate! My size 7. I really like Fitflop products. They apparently did little to no real-world testing. The only thing I can compliment is that at least the hole is off to the side and not in the center.
