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

@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.

I use 2 subs and although I think the Swarm is a great idea, I have frightening dreams about being attacked by a swarm of woofers...otherwise yeh, I get it.

@audiokinesis no no no, with your midbass driver I think the 80 hz works wonderful, actually I run mine 60 below, don't you dare touch my crossover Duke, sounds perfect the way it is
