I did some testing this morning on the inuke and wrote some numbers down but then I realized I couldn't compare that to the CV5000 since I was running the heavy hitting LFE scenes like How To Train Your Dragon etc. from the Scuba Steve disk. I used a HPF on the inuke and I won't be able to do that with the CV 5000.
So, I re-ran some music and a scene from the movie Avatar since I didn't think it is known for a lot of under 20hz bass.
I used the scene where he says, "these dumb bastards just aren't getting it, time to turn up the heat". There are some explosions after that and that's what I used to compare the amps.
So here is the comparison.
215's Full range no HPF. The numbers below are the exact volume where I saw the slightest flickering of the clip light, -.05 db's less on the master volume and no flickering of the clip light whatsoever.
CV 5000: +2.5
For music I picked a song by Pendulum called 9000 Miles. There is some really nice bass around the 2:00 minute mark so that's what I used.
CV 5000: + 7.5
Inuke: - 0.5
The other song I used was Disposable Heroes by Metallica.
CV 5000: + 8.5
I also tried out the Avatar scene running the 215's with subs, I only did this with the CV5000 here is what I got:
215's set to Large/Subs on (so, no LFE goes to the 215's but other bass does)
Ok, a couple things here. First off I was really surprised how much of a difference there was between the CV and inuke. Now, it could be that I don't have the gain structure or whatever setup exactly optimal on the inuke, but I have it set so that the input clip lights and output clip lights light up at the same time, plus I did try lowering/raising the speaker trims from the AVR and raising/lowering the sub gain on the inuke and I kept getting clipping at the exact same volume as before.
I would have guessed that the CV would have had 4-5 db advantage, but it's more like 6-8 - at least with this very unscientific test.
Am I bummed that I can no longer go to crazy +12, +15 or + whatever levels of the 212's? No. I can still go to +6.5 as long as I run the mains as large with the subs going at the same time. That is pretty damn good. I bet if I cross the 215's at 50 or even 80hz I could go +10...
Oh, one more thing. As usual the CV doesn't get ANY louder at all when pushed to clipping but the inuke sounds like a jet plane taking off when pushed to clipping. Still, I want to try the 6000 because I absolutely love the dsp of the inuke.
