I'm glad you asked, and ideas are welcome! I'm not an audio pro and I suck at physics.

I'm at work but I fired up Skitch and made this ridiculous little drawing, which should explain the situation somewhat.

But back to business, with this nice house we don't really need to do much. The log walls absorb a lot, while leaving a nice little lively touch that makes it not feel like a padded room (one of my friends had a padded room before for music, and I've decided I definitely prefer a room that feels a little bit alive).

My friend has this DSpeaker Anti-Mode 2.0 for room correction

The same friend has two Genelec 8330A active speakers that could do room correction on their own

Then we have a previous model of the Genelec F One form factor subwoofer, I can't remember the model number, which is alphabet soup, even though it's connected to my system at home.

The Genelecs are both compact, durable and easy to transport, and we have telecope model stands for them. They have a super nice mid range for guitar and the human voice, and they're also quite nice to look at.

When we set up the space, we basically let the DSpeaker box do its frequency swipes for ten minutes or so. We'd be fine without it even, but it just clears up the bass so nicely.

> Human beings don't listen to linear sine sweeps. We listen to music. ...

This is irrelevant. They're measuring frequency response, not trying to map the entire world of psychoacoustics. Log sin wave sweeps are a perfectly adequate way of measuring a transducer.

> Sine wave measurements of audio gear ignore impulse response, intermodulation distortion, phase shift, and a host of other real-world physical device responses to real-world musical signals.

No, when you do a sin sweep and measure the impedance you can recover all that. Pick up a basic textbook on loudspeaker testing.

> Scientific, reductionist thinking is inadequate to get an accurate picture of the factors that matter to human listeners.

You are completely mistaken. Here's the research itself:

Learning from it will require you to shed the chip on your shoulder, but it will put you miles ahead of your peers in understanding what's actually going on when we listen to music vs all the commonly repeated mythology.
