Speaker issue - REW measurements What causes this?

[harvardian]

In room response. at tweeter height. 0 degree mic.
See the peak at 1K. Also shows distortion here.
BG Neo8 - broken? Ringing? Thoughts

 

[harvardian]

xover points (as designed)

What are the difference between orange and green measurement?

 

[harvardian]

left and right speakers

 

[harvardian]

Is the mid driver wired backwards?

 

[sesebe]

You measured in the same position? Or in the listening position?
Is simple to check, just exchange the driver from one speaker with the driver from the next speaker.

 

[wesayso]

Simply swapping speaker positions could do the same.

 

[harvardian]

Swapped drivers. Issue remained with right speaker.
Changed preamp outputs - same
swapped amplifier channels - same

Crossover issue?

 

[harvardian]

I will swap positions next. But same when measure 1m away at midrange

 

[harvardian]

Swapped and still similar. I suspect crossover issue. Loose wire? short, bad value?

 

[sesebe]

I do not know.
Personally I will check components from crossover with multimetre and/or R-L-C bridge.

 

[harvardian]

found unsoldered crossover joint..

Unless you are measuring close up, and/or gated any of this can be room related.



Move your mic towards/away from speaker and see if these dips and peaks move left/right on the measurements.

😕Both speakers should measure fairly the same even in an unequal room if close mic and if same angle/height which is more critical...

To me it doesn't make any sense since the peak could be a disconnect notch filter...? I don't see how one driver could boost the other at this FQ maybe only if the filter affects both drivers?

Did you checked all connections, checked the cabinet for lose screws and the driver is secured?

To me the 2 measurements show almost totally different speakers at all frequencies, this makes no sense
