Too much power to power compression drivers
I have always tri-amped my system which consists of two Peavey SP2 top cabinets which contains a 15 inch black widow speaker and an RX22 1 inch compression driver with an asymmetrical horn. My subs consist of two Peavey SP 218's--dual 18 inch (black widows) @ 600 watts continuous, 1200 watts program and 2400 watts peak for each cabinet. I have 3 of the Inuke amp's--NU1000 for the high end, the NU3000 for the mids and the NU6000 for the subs.
The NU1000 is actually way more power than is needed. I have to have the volume controls turned way down or it over powers the mids. Once I got everything balanced between the highs, mids and low end, I was astounded at the quality of the sound and the amount of headroom. I was only lighting up the bottom light of each amp--barely anything from the NU1000, but I had clear flashing bottom lights on the NU3000 and NU6000. The second lights up did not come on and the volume was deafening.
I gave one of my systems to my son which has the same speaker set up but I used the EP4000--enough for thunderous bass and the EPX3000's. for mids and high. I used these amps for a lot of dances and outdoor sound system services at community festivals. These amps still work and they were enough.
I am pleased with the very light weights of the 3 NU amps, their clarity and richness of sound and their power. I think the opinions of those claiming the Behringer NU amps is overrated do not have the practical experience I have on the road. These amps are very powerful and will serve my needs for clarity and headroom.
