Hey guys, sorry if my english is bad, im from Germany but i hope you can understand me.

I have a Umik-1 and took a messurement from my System with two KEF Kube 12b Subwoofers. Specs say they go just to 22hz down

But the Messurements says that my subs goes down to 8-9hz! With high output. But when i play testtones from 20-0hz i didn t hear or feel much, but in the kitchen the cupboards start to wobble slightly

now my question, is the Messurement right? And thats all you can hear below 20hz?

The Greenline and Blueone is my Setup with two subs and red with just one

Difficult to tell with smoothing applied, better looking at the low frequencies with no smoothing. The spec of those subs is good, if they are in corners or against walls boundary gain and room contributions may help extend the response.

Thanks for the answare. Here is now a picture with no smoothing, but it changes not much. So do you think the umik and the software are right? i read in some Test from other subwoofers, that meassurment can show more Bassresponse way below the specs but hat this only look good for messurements but you can't hear it in real life, and others tells me that you can fell bass below 20hz, but i didn't feel much, even the graph tells that i have over 90db in the 11hz region, thats because i ask....

It looks plausible, but better posting an mdat file with some measurements to check further.

Wow that Sub seems ideal. It is a sealed box, so the LF roll will be very gradual and very extended.
