You need these now!

This is a must if you own a Genelec speaker. The UI is clean and intuitive, calibrations are very quick and easy, and it helps 1) show you how bad your room is and 2) correct where appropriate.

GLM kit does not add gain to address dips, just helps attenuate peaks in your curve relative to your room. My advice: get this, treat your room, and don't obsess about a perfect flat curve.

I use this with a pair of 8341s, and honestly the only time I've ever not used GLM was when I bypass the curve to see how much worse it sounds without decent peak attenuation.

Your Genelec's are not complete if you don't get this

My room is treated and the 8341As sounded great so I didn't purchase this accessory, no let's say necessity, for about 18 months. It annoyed me that it wasn't included with a very expensive set of monitors. I finally decided to spend the... dollars and I'm glad I did. The imaging improved and I thought it was already great. I can make small eq changes and easily hear the impact. I'm on a mac with Catalina so I'm running the Beta 4.0 version that anyone can download and it's working fine. You've already spent a bit on your Genelec's so tip yourself you won't be sorry.
Rated 5/5

Making Great Even Greater

I just purchased a Genelec SAM speaker and sub setup which before calibration sounded pretty amazing. But after using the GLM calibration system, everything became even clearer and tighter with even more detail popping out. I really love the phase alignment calibration between the monitors and sub as that really improves the bass tightness and detail.

To any PC users out there, make sure to check the "Use Autocal Cloud" option before calibrating.

Worth it?

I have tried other room correction solutions and this is by far the best. If you are getting a SAM system, you have to have this, otherwise you will never get the performance you desire.

A must have

I have the cheaper room calibration software. The Genelec GLM software with the Smart Active Monitor system is far more accurate, there is no comparison. Genelec USA has by far offered the best customer service I have seen since the 80’s. I can’t thank them enough.
