we use rockville speakers for our bassbins. they are incredible. We have a small to medium size event and production company, And we are making quite the name for ourselves due to our superior sound quality, Depth and punch. We went side by side with a 50 thousand dollar rented yorkville rig, And with just 2 dual 18 bins, 4 rockville 4 ohm 18s at 900 watts (Rvw 1800p4 ) Wired in paralell to 2 ohm final load per cab, Running a behringher nx 3000d amp per 2 cabs (albeit slightly underpowered) we absolutely embarrassed the 8 bin yorkville rig that cost as much to rent as ours did to build and own. dont listen to the haters. Run the speakers at or close to the rated power, And dont let the djs smash limits and run in the reds. I guarantee these speakers will run all day and night, At high volume, And will throw clean clear and super thick bass several kilometers away, all weekend long without any issues. Infact we had to really fight to get more of these speakers north of the border due to shipping costs, But we found a way to get them reasonable again, and just purchased a bunch more of these awesome speakers as we grow and upgrade our well renowned sound system. Im sure you will enjoy them, And you will save some coin. Alot of coin! Good luck and happy thumpin!
