1hz being played on a Sundown X15 v1, killer home audio infrasonics.

Sounds like a really messed up washing machine when you step away from it 😅😅

@@thr0nic yeah and some people like infrabass a ton i for one say 28hz and ups good

[@experimenkun5794]

I would like to see how it does on a pure sine wave frequency lol. Because on those low frequency tone videos, it doesn't really contain pure sine wave frequency at all. It's more likely a combination of low and higher frequency bass, that's why you can hear the bass. But still, it's a very cool test!

[@erikbritz8095]

@@experimenkun5794 this depends on which you choose plus i would have to input more power on a pure sine wave as we know their not as loud, i can redo this later on using FL Studio 🫡 but that might take a bit funds are low and i need a laptop for that job 🤣

@@erikbritz8095 FL Studio is really easy to run if you're doing that sort of stuff in it, i ran FL Studio 20 on a laptop from 2010 for a while and it did it no problem

[@bubleman2196]

Use the frequency generator app on your phone if you have a audio jack to get a pure sinewave 1hz, not this 30hz with breaks. One amplitude was performed, but at 30hz with a bit of downtime.

[@erikbritz8095]

Did you run it through a DAW to check the Frequency? If not then how is the claim of 30Hz accurate? No Hate its just easier to check with a DAW program however i'll redo this test in a week or two with a signal generator for fun. 🫡

[@bubleman2196]

@@erikbritz8095 All I know is that one hertz ain't moving like that. Open any frequency generator and you see the wave is much slower. I just had a guess at the frequency. What was played there was a series of 20 or 30hz bursts, each long one pulse. So for example a 30hz burst playing for 33ms, then the cone has no movement. In a sinewave the speed of the cone is constant and only big rotary subwoofers can reproduce 1hz. Your cone area isn't anywhere near big enough to create sound pressure that you can feel/see. You also can't hear 1hz, only it's resonances reaching 15-20+hz

@@bubleman2196 Yes no the "Audible" side of this is port noise nothing more, but 30hz i dont think so...30hz does not peak in this space at all and sounds completely different. However i agree a tone generator or DAW played 1hz tone will be more accurate, but this is not 30hz, anyway though this is more for fun i have no intentions of doing Numbers at 1hz or anything like that our best with this exact box was 145DB@28hz we then swapped to a new box and more power and our best jumped to 147.9DB@25hz, lowest we ran the newer enclosure was 18hz where we did 140DB@18hz alby after demos etc. So infrasonics is possible just not loudly.

Need to put it in a vehicle and see what it does
