Bass- at what frequency does it change from sounding like a string to just a low tone?

Thanks, y’all.

All this information is quite helpful. My subs are SVBs, So I’m using a low pass filter set at 58 for Atc Speaker’s that go down to 48, measured at six not three drop off.

I guess what I’m really after is when subs are operating properly, or even with just floor standers, how low am I supposed to be able to hear notes as they would sound with actual Instruments in the room?

I am worried that my system doesn’t sound as good as it could, and that maybe other people hear much more than tones at frequencies lower than mine.

Beats me.

What are your main speakers? btw, always good to post your system in your profile, saves asking additional questions:)

There's not a lot going on below 40hz,except maybe electronically enhanced tones or pipe organ tones.What there is normally are low tones and resonances. If your floors and walls are "singing" along than those tones won't sound as clear as you'd like. This is a link to some frequency charts that illustrate where the instruments and vocals reside that might interest you.https://www.bing.com/images/search?view=detailV2&ccid=fjNn8kLi&id=981426F355CF8B0314AEA0066F324A52613C25B5&thid=OIP.fjNn8kLitMiphe7sH3ZolgHaIR&mediaurl=https%3A%2F%2Fexternal-preview.redd.it%2FG-ZpqOjDR1r1xMXzByqv2OX0cRK5KXIpz3VGMfXYpkw.jpg%3Fauto%3Dwebp%26s%3Dfe5718bae0049cc23247e7345c320538c4fe93fe&cdnurl=https%3A%2F%2Fth.bing.com%2Fth%2Fid%2FR.7e3367f242e2b4c8a985eeec1f766896%3Frik%3DtSU8YVJKMm8GoA%26pid%3DImgRaw%26r%3D0&exph=2151&expw=1924&q=frequency+chart+for+instruments&simid=608000213540172012&form=IRPRST&ck=98CFCCC39A2D2047CC2604D79D0D6323&selectedindex=7&ajaxhist=0&ajaxserp=0&vt=4&sim=11

I like the sound of sine waves from 20 Hz and up. Billie Eilish is very good for this :-)

Bed aware not to set the level on your subs too high or you will only hear the "sound". And use dsp.

I have ATC SCM40 mains, 2 SVB3000s, along with an A308 MF amp, a good streamer, and a good DAC. I also have a very challenging room with no options to improve anything at this point, room-wise. I don't know if I've ever looked at my profile.

So I gather that for the most part, the lowest sounds aren't within the range of  instruments per se, and the clarity of these is room dependent.

Thanks for the links.
