I've been toying with building my own system for a while, maybe centered around one of the Onkyo TX-SRxxx receivers i've been using.
After working at component level with computers for the past 15 years i'm tired of custom chips and want to get into building something I can really appreciate, preferably out of wood, transistors and components I can actually see without an electron microscope.
Anyhow, on to my question:
At the moment I'm running a very modest 5:1 setup with a sealed 10" subwoofer based around the Dayton SA70 plate amp.
I was experimenting with stuffing and using sine-wave tones to hear what kind of response I was getting from the enclosure - my wife was in the room at the time sitting around 11' away from the subwoofer.
I gradually increased the volume on the amplifier and played a series of tones between 30 and 50Hz.
Immediately my wife told me to turn it off because she was in pain, apparently it hurt the back of her throat and ears, she was in pain for a few minutes after the tones.
I don't think they were very loud, nothing like the volume of music I regularly play in the daytime (I work from home).
Can anybody explain why she felt this pain from these tones? I understand resonant frequency however her throat isn't anywhere near a half-wave long at 30Hz 😕
Anyhow, great forum and the knowledge and helpfulness of the folk here blow me away.

Hi Phonic and welcome to the forums.
To answer your question, I think the music was so beautiful that it got her all choked up. 😉
Actually, that is strange. It may just be one of those things idiosyncratic to your wife. I hope there were no lasting effects.

Funny you should mention that SY, as that's sort of what I suffer from. As I tire or imbibe, they begin collapsing and that has a definite effect on the bass. It basically disappears and no amount of EQ is going to help. I can still feel the thump but cannot hear it. I have had no ill effects from it though.
If hers are clogged though, that could be a whole new problem.
