HomePod Has anyone measured OG Homepod Lowest Frequency ?

uller6 said:
I think they are rated down to 50 Hz. rtings has a decent spectral analysis which approx. confirms this: https://www.rtings.com/speaker/tool...od-mini/1719/19606?usage=10159&threshold=0.10

is this what you are talking about ?

Yes, that's what I was talking about. Although, apparently this website measures response down to 20 Hz, but rolloff starting at 70 Hz: https://www.audiosciencereview.com/forum/index.php?threads/apple-homepod-measurement.8425/

When I said this to a couple of guys that the Homepod can reach a lower frequency of 20Hz they laughed about it saying that no way such a tiny 4" woofer is going to be able to produce that kind of sound and reach that frequency, it is simple physics it needs movement for Air and larger the driver larger is the movement of Air and hence the BASS. So 20Hz is a hogwash basically.

By the way what does roll of at 70Hz mean ? Don't know what it means ?

Why do your friends think a 4" speaker is incapable of producing a 20 Hz tone? That's patently false. Some small speakers can and other small speakers can't go that low - it depends on speaker & enclosure design.

The 70 Hz rolloff means that below 70 Hz the output power decreases substantially - so the speaker is less effective at producing frequencies below 70 Hz. They are however still there.

If you have one yourself you can test with a 20 Hz test tone - search for 20 Hz test tone on YouTube.

I just did this, and both my M1 iMac and HomePod can reproduce 20 Hz. The M1 iMac surprisingly sounds better than the HomePod at 20 Hz, but they can both reproduce the frequency.

Graph show 20 Hz at -25db in relation to 70 Hz, basically inaudible. Woofers have what is called their free air resonance, a point where they begin to roll off. Stiffer cones, smaller cones have higher free air res. Some woofers have very low free air res and use a sealed enclosure to achieve extended bass response (acoustic suspension). My Home Pod sounds like it peaks about 120 Hz and uses sealed enclosure to get it down to about 55 Hz. Frequency response specs are measured at the -3db points for low and high frequencies, so 19kHz is being generous.
