Thought you guys might like to see a slightly different graph - I think this might be slightly more representative of the sonic signature. It gels with what I'm hearing anyway.
Usual disclaimer:
The graphs below are generated using the Vibro Veritas coupler and ARTA software. Ken Ball (ALO/Campfire) graciously provided me with measurement data which I have used to recalibrate my Veritas so that it mimics an IEC 711 measurement standard (Ken uses two separate BK ear simulators, we measured the same set of IEMs, and I built my calibration curve from shared data). I do not claim that this data is 100% accurate, but it is very consistent, and is as close as I can get to the IEC 711 standard on my budget.
I do not claim that the measurements are in any way more accurate than anyone else's, but they have been proven to be consistent and I think they should be enough to give a reasonable idea of response - especially if you've followed any of my other reviews. When measuring I always use crystal foam tips (so medium bore opening) - and the reason I use them is for very consistent seal and placement depth in the coupler. I use the same amp (E11K) for all my measurements - and output is under 1 ohm.
First lets look at the Dipper with all switches in the off position:
A little more V shaped than reference - but pretty darn good.
OK - what about turning just the treble on
And just the mids on
Now just the bass on
Some pretty nice configurations - and no filters to muck around with (although the little switches are a bit tricky)
So what if we turn them all on?
And how is the quality of the channel matching?
(this was with all the switches on)
I'll have more for you - including photos - as soon as start the review process in about a week. Have a couple I need to finish first.
Oh - and they sound pretty darn good.
Quite interesting stuff here, thanks!
