After all the emphasis on this not being a neutral product it is sort of a release for me being able to back it up with some measurements.

Stage 7

The measurements seem to continuously hump from 6kHz to 300Hz and have a peak of 7/8kHz (channel dependent) before once again declining. Quite a simple graph actually and other than the 7/8kHz (and beyond) peaks showing a variance in channels, matching is not to shabby, especially over 7 drivers and 4 crossover points, but then again I have to point out I still got a better tolerance with my the £110 Dunu Titan 3 I last measured but then as measured there I have got a lot worse with top CIEMs so won’t hugely whine about these.


Now interestingly in contrast to the research Harschacoustics had made regarding what a neutral curve should be like these do an almost opposite effect. Harsch seemed set on a 4kHz boost and then a 7kHz drop off but these fall off quite heavily at 2kHz likely causing the wooly midrange and boost at 7kHz which I guess could cause problems but not to my ears.

Stage 7 vs UERM

Now having mentioned the UERM more than enough I thought I should show you a comparison in the measurements and while not huge contrast, when you look closer there is more to it that simply the rhines having more bass. I openly have claimed the UERM lack a little upper midrange but no where near as much as the 7 and also they pick up a little at 4kHz. Also at 7kHz the UERM are dipped, as is apparently ideal and boost later, nearer 9kHz where the Stage 7 is already deteriorating.

Stage 7 vs VE6 X2

I thought another one that would interest you folks is a comparison to the VE6, for which I choose the more balanced X2 configuration and again it much more balanced with less bass and more upper midrange but strangely as the same 7kHz peaking, must be a german thing huh.
