Multiple Small Subs - Geddes Approach

[Arez]

This topic gets a lot of attention on ASR...how many recordings are mono bass vs stereo bass. Analysis of tracks, including older CD tracks, has been showing more is recorded in stereo than commonly presumed.
Maybe the old practice of needing to mono bass for vinyl, died off earlier and more prevalently than realized?

And when the wavelengths in a room are long enough to sum as one?
Using multiple subs ontop. The advantage of "stereo" bass is what?

Thats how i read his comment at least. Near 100% summation at those frequencies.

How does the length of rooms have anything to do with wavelength summations? Summations, not formations from modes.

I think removing the idea of recordings predominantly are mono bass, is a first step in questioning how bass is heard in rooms.

I use my system for gaming and movies, not just music, and an accurate depiction of sub bass in the stereo field is important to me, but I am the minority...

where do you cross to your subs? How many subs do you employ?

I use my subwoofers a bit differently depending on the content.
For music, I run four subs in stereo bass mode. Placement is manual for smoothest response. No active delays.
For movies, I go all in with six subs non-stereo. Here DSP handles all the delays for smoothest and constructive interference.

I’ve found that setting the crossover around 60Hz hits the sweet spot subjectively.
One of the subwoofers is placed behind the setup, so it’s not visible in the picture.
