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

" 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

My Swarm is trained not to attack, you have 2 subs? That's heresy :) with your perfect speakers

Thank you Luis! 

I was referring to the hypothetical situation where an 80 Hz crossover was not high enough.

One time we were integrating a Swarm with a system that was horn loaded down to 80 Hz, but it turned out that the response started rolling off at about 150 Hz and then the rolloff accelerated below 80 Hz. So we placed two Swarm units near the main speakers and drove them with one amplifier and rolled them off at about 140 Hz, and then the other two were placed much further from the main speakers and were rolled off around 60 Hz. We used the parametric EQ’s to fine-tune the blending.

Something like that would be the work-around if the crossover needed to be higher than 80 Hz.
