Looks like room bass node at 30hz.
Given the flat response above 10khz, I'd say 3 way floorstanding speaker with 8 inch woofer.
Guess How Big My Speakers Are
If you read any of my threads on here or looked at my virtual system you probably already know the answer to this question, but for those who have not, try this as a thought exercise. Given this plot alone how big a speaker do you think this is?
Hints:
- 2’ from sides, 1.5’ from rear
- Ported
- Not horns
- No EQ applied. This is the natural in room response using short sine sweeps.
- For a living room this is a well treated room with GIK soffit traps, bass traps and diffusion panels strategically placed.
I’ll reveal my answer if we get 5 guesses or more. :)
