![]() Well with the iNuke in place of the Crown I was able to totally eliminate the resonance at 40Hz and now I’m able to actually increase the volume without things vibrating all over the house like before. Anyhow, the plan was not more than a thought really and then those nasty online retailers put the iNukes on sale and I bought one…….a Behringer nu3000dsp. ![]() Why……because it’s fun, it’s a sickness, bigger is better, I have more money than I know what to do with…….yes.except for the last one. Of course this made me think of the Behringer iNuke again.Īs many of you who regularly visit this forum know, rarely it is one project and done and now I’m thinking about building another subwoofer. I was quite happy with the overall results of the subwoofer/amplifier pairing and using REW could see the response extended to 12Hz (room gain), but I did have significant bump in the 40Hz region. Keep in mind this measurement does not take distortion into consideration. That measurement paired with the impedance from Dayton’s datasheet, 4.5ohms at 60Hz, resulted in 1058W. Using the only equipment on hand, a DVM, and 60Hz test tones I measured 69 Vrms. Upon receiving the Crown I was very impressed with how it drove the Ultimax, but the engineer in me wanted to know more. The Carvin just had very limited information, reviews and resources available online therefore I was not comfortable going that route. The Behringer had limited connection options, although that could be remedied with adaptors, and had fan noise issues. At the time, the three amplifiers under consideration were Behringer NU1000dsp, Crown XLS1000 and the Carvin HD1000. I wanted a stand-alone amplifier, because I could also then use it drive a pair of PA speakers for entertaining (birthday and graduation parties) and as an amp for my son’s guitar. ![]() Last Spring I was building a sub comprised of one of Erich’s 3cuft flat packs and the newly released Dayton Audio UM15-22 and as part of the build I needed to buy an amplifier.
