I’ve hired an acoustician to “tune” my room using microphones and the PSI Active Bass Traps. Has anyone hired a professional to tune your room. How did it go?
Closest I have come to that was to measure my (previous) room with a mic and REW, and share the graph with the fine folks at GIK acoustics. They helped me choose some of their products. We could never fix the 40hz “boom” in my tiny room, without many, large, tuned bass traps that would have take a third of the room volume.
Perhaps the active bass traps would have worked better.
my new room is much bigger, and dwarfs my room treatments. When I finish “placing” my system, I will probably run the REW room measurement, and figure out where to go.
I’m told that the placement of the active room traps is critical to optimize them. I ordered 4 of them for a 10 x 20 room (which is overkill).
In a previous life, yes with mixed results, some people were thrilled others were less soo.
But my view now is more be happy with what you can achieve with an esthetic focus, if the acoustic treatment doesn’t detract from the space/ambiance/atmosphere great but large bass traps that made the space feel small got to me in the long run as did thick slats for a friend and another person I know wanted the thick felt curtains gone before they had even finished drilling the rails.

I do acoustic treatment and have used the PSI in multiple occasions now. Important is to not make the room dead but keep the RT60 around 0,5 - O,55 (preferably over the whole freq spectrum. I do use a lot of Artnovion Alps and Lagos diffusors. It’s all about keeping the balance between liveliness of the music and controlling the energy in the room.
Curtains for me don’t work…they have to be thick and heavy and block daylight while enjoying music, especially in a living room where you enjoy music with your family.
It’s absolutely important to include the acoustics in the room and match aesthetics. Have a look at the show pictures from Munich from recent years. it will give you an idea.

Hi Frank - my big issue is bass overhang in my room. I’m around 800 ms decay from around 20 Hz to around 170 Hz or so.
Hi Aklein55,
Your room is quite dry and rt is more than home theatre dry. Low freq at 800ms is not so bad… if you want to further reduce that. Get some AVAA active bass traps and work with them to further reduce it.
Just make sure you don’t make the music sounds studio dry and not lively energetic. I would recommende less damping and get a bit more diffusion … yet this is only
1 measurement and I haven’t heard your system next to this measurement 
Thanks Frank - I have 4 AVAA active bass traps coming. I’m not sure what I’m doing - so that’s why I hired someone who can help with the room. It’s a bit of a dark science to me.
When you place the avaa, do not fiddle with the knob to adjust the absorption first. First find the spots where they are the most effective by placing them in different locations. Bear in mind they work with the pressure points from your room. Some of them might be 3 feet up. Be creative and let your ears do the work. Play some files with 30Hz - 40 Hz but also some double bass tracks with natural notes. Enjoy the process. It takes time.
Thanks Frank - that’s super interesting. I come from headphones - which have the opposite issue of a very lacking low-end bass response - but a lot of accuracy. I need to find the happy midpoint.
