I use this product as a reference monitor, I only have one and use it in Mono to check the mid-range of my mixes. These would not be suitable as your only monitors, but when used to check mixes they are incredible at highlighting mid-range issues, vocal and reverb levels and how the bass will translate on smaller systems. For the purpose of referencing these are literally incredible. They are the classic 'bad' speaker check that makes you work really hard to get a good sound. However, once I earned the idiosyncrasies of the mix cubes and got my mixes sounding clean and clear on them, the translation to different systems was solid. An incredibly useful tool when used in the right way. I am so happy with my purchase.
