Mix Cubes Are outstanding
I've been using NS-10Ms as my go to near field monitors for 15 years now. I installed a set of passive MixCubes about two weeks ago and I will never go back to the NS-10Ms. I suddenly heard the good bad and ugly of my recordings. Things the 10Ms never could reveal. What makes them extremely cool is the fact that what you hear is what comes out on a car stereo, iPad , or any current listing device everyone is using. In fact I can now switch between my sony professional dynamic head phones and the cubes and they sound almost identical with exception to the low end frequencies accompanying the bass and kick drum.
If you are still mixing with home stereo speakers or any other new fanged near field speakers, do yourself a favor and drop the bucks and pick up a pair. Trust me you will be blown away by the accuracy and they will immediately improve your mix.
