I had been using the same passive Alesis monitors for close to 20 years. The Focal Alpha 65s are a HUGE upgrade. I also finally had the ability to add proper sound treatment to my room, and in the short time I've used these I can hear a number of problems in my old mixes. I have never owned monitors of this quality to compare these against, but I can say that the low end seems very properly emphasized in relation to the rest of the spectrum (I have a couple of mixes where the old monitors had me pushing it too far) . I can also hear some issues with highs and mids that were apparent when listening on other audio systems but not when I was mixing on my old monitors. Still haven't had enough time to really get to know these well, but the improvement has already been very noticeable. I am very satisfied with this purchase.
