I think Trever, the jolly looking fellow standing next to the test cabinet in my shop would beg to differ. He was getting queasy with that cabinet and the two lo-max going! Add another 4x18” I bet he’d bail out of the shop!
Gonna call it a night and hit the hardware tomorrow for paint. Next big project will be the shelf to put them all on...
That "malady" is something I experienced when I worked for a big electronics chain. With me it was induced by competition car stereos, those that needed external power for all the amplifiers . When that time of year rolled around, vendors like Alpine, Pioneer and Clarion would set up their entrants inside the store, usually near the front, the largest open area.
When those systems were demoed at high volume, the extreme bass output from the subwoofers caused me to feel nausious. There was no urge whatsoever for me to sit inside one of those cars with the stereo on. Just the opposite, stand far away.
I was unaware of any other staff member experiencing the same thing which made me think that sensation was uncommon. Sounds like your bud Trevor has the same sensitivity.
