Home Speaker Asylum

General speaker questions for audio and home theater.

RE: Averaging of multiple locations

terribly bad honestly.

with speaker placement, you can deal with this. but honetly, any speaker that Ive measured which were closer to 2 feet to the back wall had very bad peaks and dips in the bass region up to 300hz. up to the god damn middle C.
its so important to try to control the effect of the room.

I have measured all my speaker, and as soon as they are too close to the back wall, for get it, you get magnificient 15 db dips. its almost certain.

then, your listening position will also add to the party. when I move my mic, I see huge change. ideally, you must be far from the back wall also as each time I measured with the listening position to close to the back wall, dips and peaks appears automatically.

I sit 3.5 feet away from the back wall and my speakers are 2 feet away from the front wall.
I also have my room well treated (bass traps and first reflection poiints), which reduced the peaks and dips another 4-5 db. I now have +- 4-5 db from flat from 40hz to 250 hz, then 2-3 db flat from 250hz to 20khz.

without treatment and placement, you will easily have a +-10db to 15 db from flat from 40hz to 250hz.

its a very serious issue. very serious. no matter the speaker, you hear your room first and foremost.
