[QUOTE="Helge A. Bentsen, post: 350, member: 263"] Anybody here got some experience with out-of-band EQ on SB1000e? Current DUT, a Lake LM26(excellent piece of kit btw), means that I've probably made a gazillion different measurements on my current rig(sh50+sb1000e+ux8800). During some experiments with Mesa EQ on the L channel(2x2 sh50/sb1000) I noticed that I could eq the rig to sound pretty good and measure pretty smooth, but a lot of cut was needed around 200hz. Crossover was LR24@100hz. Because I did both array compensation and some taste-correction, the filter became quite wide and complex, but it got me where I wanted(thumbs up to Lab). Upon further experimentation, I realised that the extra cut around 200hz wasn't necessary when I muted the subs, so I started to dig around with them. I quickly found that the complexity and cut needed in the Mesa filter was reduced by a significant amount if i applied some heavy OOB-eq on the subs. I ended up with a parametric cut on 170hz, bw=0.5, -9 dB on them. At this point, I decided to redo my system tuning, and ended up with this: Subs: LR24 LP@100hz -9db@170hx, bw=0.5 Delay 3ms Tops: LR24 HP@100hz -3dB lo-shelf@300hz -2db@200hz, bw=0.2 This sounded pretty smooth to my ears. Have anybody else here experienced something similar? [/QUOTE]
