The room’s original acoustics had a noticeable peak around 44Hz.
After careful correction, the frequency response now sits perfectly flat.
The first impression? Crystal-clear transparency, like drinking pure spring water.
Adding the optical isolator took it further – the background became eerily silent, with noise and harshness virtually disappearing.
Some might dismiss it as “placebo effect,” but how can you judge without experiencing it firsthand? [Wink]

Now, about that common remark: “Genelec monitors don’t sound pleasant.”
Why would anyone use a “workbench” for enjoying music?

Here’s my perspective: Genelec isn’t designed to sugarcoat your music.
It’s a precision instrument – your trustworthy guide to discovering well-recorded albums and hearing music exactly as the artists intended.


I’ve been curious about the GLM Auto Calibration feature, and it sounds even better than I expected. That peak at 44Hz would drive me nuts, so it’s great to hear how well it smoothed out. The improvement in clarity and reduction of noise is impressive—definitely makes me want to try it myself!
