PSI Audio A25-M Side view


The most accurate 3-way studio monitor ever

“The A25-Ms are genuinely revealing monitors that can provide great insight into the components of a mix and how they fit together, or not.”

“I’ve no idea if it’s the CPR or AOI (or both) that are responsible for the abilities of the A25-Ms, or if it was simply good, traditional electro-acoustic engineering that I was hearing, but it seems to me the the number one priority of any monitor design is that it enables us to hear what’s what in a mix, and to help us make the appropriate creative decisions. The A25-Ms really excel in that regard.”
