When detailing the three types of studio monitors he uses in his Berlin studio, Jaytech mentions using just a single Alesis M1 Active Mk2 Bi-Amplified Studio Monitor, to reference his tracks in mono. He says, "Also hooked up in the corner is a single Alesis M1 Active Mk2 (my first ever monitor speakers) for mono/bass reference."

Have had these for a LONG time, I love them! Not the most accurate for monitoring a mix, the bass and treble sound a little too good. They are powered so no need for an amp, and they get really loud. I can definitely make Guitar Rig scream through these, and it sounds sweet. Lots of temptation looking around at other monitors, but no need to upgrade just yet...
These Alesis are great monitors for a first time studio setup or home/bedroom studios. Fairly well balanced and flat monitors but worth profiling in order to compensate in the mix (if need be). Sturdy, well constructed with two connection options and individual volume control. 10+ years and still going strong
