Audio Kinesis Swarm Subwoofer Awarded 2019 Golden Ear Award by Robert E. Greene

luisma31,

     The bottom octave refers to 16-32 Hz, 32-88 Hz is what is technically  referred to as the 'or so'.

Thanks Tim, I thought the bottom octave was technically 11-22 Hz (not that I can hear anything there), then you have 22-44 Hz and 44-88 HzSo what you guys speaker / audio equipment experts refer to as the "bottom octave" would be as you are describing 32 Hz (possibly what we most can hear) and 88 Hz?

@luisma31  The bottom octave is generally considered to be 20Hz to 40Hz, the second octave 40-80Hz and so on.


80Hz has a bit of a special meaning to subwoofers and the human ear because it is at about this frequency that bass appears omnidirectional to the human ear. This is partially because it takes some time for the ear to register that the bass has occurred. So it does not matter where the woofers are if they are only operating below this frequency; the rest of the speaker system (80Hz and above) provides the location information on those bass notes from their harmonics.

Thanks Ralph, that explains a lot...

" The bottom octave is generally considered to be 20Hz to 40Hz, the second octave 40-80Hz and so on. "
This is what I had in mind when I was talking about "the bottom octave or so".  

I don't normally recommend running the Swarm higher than about 80 Hz because the ear may be able to detect the locations of subs that are well away from the main speakers, and that would be distracting.  That being said, there are work-arounds if the need arises to cross over higher up.
