The Avantone Active MixCubes are powered mini monitors, quite similar in design to the classic Auratone 5C Sound Cubes. Sure, it's important to have a high fidelity set of main studio monitors...but in today's world of people listening to music on bass-challenged ear buds and laptop speakers, occasionally referencing on a smaller system is crucial -- and the MixCubes are the perfect tool for this particular job. Grab a set for stereo, or just one for checking mono compatibility and finding the perfect spot for the lead vocal.
