About 41Hz Audio

41Hz Audio is a small business that specializes in audio kits for DIY and OEMs. Our aim is to produce and maintain high quality, unique designs with decent prices. They are all available via the shop pages and we send all over the world.

We also do consulting in electronics and measurement tecniques.

But 41Hz Audio is just as much an active and very international community, which you can see best via our forum. Without the community we could not exist!

41Hz is the frequency of the lowest note on a double bass or electric bass guitar
