The Avantone Mixcube is a modern day update of the legendary Auratone 5C, possibly the original ‘grot-box’.
It has a very limited frequency range, dropping off sharply at around 80Hz, so the mids are heavily pronounced, making it invaluable for setting vocal levels in mixing. The story goes that Quincy Jones mixed the majority of Thriller on an Auratone only using the main speakers to check every now and again.
We have one sitting on the desk so we can check mono compatibility, check how it will sound on a TV/kitchen stereo and use its uncanny ability to reveal mid-range distortion that can be lost on bigger speakers.
Naturally, everything that goes through it sounds terrible. But if it sounds passable on the Mixcube, it’ll work everywhere else too.
