Is there a general guideline for how far to sit away from a speaker?
I realize that this is very speakers and driver alignment specific, but as a rule of thumb...
do you need to sit at least 10' away from a 10" driver?
8' from a 8"?
6' from a 6"?
I made the numbers up for illustration purposes, but does such a rule of thumb exist?

I felt it has something to do with the driver array or the height or distance between drivers as well.

Rule of Thirds is a good starting point:
Place your loudspeakers one third the total distance of the room from the rear wall and your listening position the same one third away from the opposite wall.
For example, let’s say you have a room that’s 15 feet long and 12 feet wide. The loudspeakers would be placed 5 feet from the rear wall and your couch would be 5 feet out from the opposite wall.

I agree with loop 7 that the room size is the determining factor. Also there is a general rule of placement. Ill research my archives unless someone else has it handy. But its about room size mostly. |

Distance based on woofer size? No.

Here are two examples of being too close.   |

Here are two examples of being too close. Well now that's all a matter of opinion.  |

Here are two examples of being too close. The first guy is to the right of the sweet spot. Unforgivable. |

Another thing to consider is reflective surfaces. The Bose 901's had multiple drivers of the same size angled different directions to bounce sound off walls around the room. It fooled you by making an effect that was pretty cool and spacious. With two channel small or large speakers you do not want reflected sound reaching your ears within too many milliseconds of sounds directly from the drivers because your hearing and brain do not processes as arriving at the same time. They call that something as bad and I can not remember it what you call it right now. An old trick is to take a mirror and slide it down the walls on each side from the speakers to your listening position. If you can see your speaker drivers between those points then sound is reflecting off the walls or other hard surfaces in the room. You can put something to absorb those sounds or you can just have enough space to the sides that there are no reflection points. I like a big room and soft walls. Myself I do not have a sweet spot chair for two channel listening. I am done with those days other than when I am setting up my speakers or letting others hear what a good sound stage sounds like with a good system, speakers and proper set up. I just enjoy music filling the room and not sounding like a couple of speakers. |

I do not have a proper listening room. It is a shared space. Couch on side wall, speakers on opposite wall (long one in the room). Big window in between. Brick fireplace on one short wall, half wall to kitchen is the opposite to that.
I am close to buying a pair of Tekton and I am deciding on the Lore (10" Driver) or Lore Reference (8" Driver). I only sit 8ft away.
I really like the idea of the 30-30 frequency response of the Lore, but really think they may be too big for my room. 12x18

Sit where it sounds best
I have a dedicated 11 X 14 for 2 ch that sounds great
Too many factors to generalize sitting distance from drive unit sizes

How does one settle on a straight answer without also considering preferred volume or listening level, which is personal, subjective, and therefore highly variable?

If the speaker is small enough, stick it in your ear!

S x WD / SQRTDVC x IVCW / CV where S=speed of sound in MPH, WD=woofer diameter in inches, SQRTDVC=Square Root of Driver Voice Coil Diameter in inches, IVCW=the Inverse of the number of Voice Coil Windings and CV=Cabinet Volume in cubic feet. The result
is in feet. So take a 12" woofer with a 2" voice coil with 198 winds in a 4 cubic feet cabinet you'd have 767 x 12 / 1.414 x .005 / 4 = 8.136 feet. Simple!

I was going to buy pendragons, he said they were overkill for my room, sold me Enzo's, seems to know what he is talking about. YMMV |

I agree, but thats only on Tuesday! The rest of the week you need to multiply by F(x), simple! 😋 |

It also depends on what kind of speakers you have. Dipoles and bipoles typically sound better the further away from the back wall you can get them. And reflections from these speakers is actually desired.
Unfortunately, since ergonomics usually play a large part in the average home, having speakers 5 feet out from the wall isn't typically practical.
