raymond hing, your RTA also shows an abnomal dip on the 400hz. because usually midbase won't be affected with room that much, that's why I think it has to do something with the speaker. Not trying to bite and not release. sorry.

I see. Actually, it is not at "dip" at 400Hz, it is a "rise" of 6.6dB above reference if you check the graph.

In fact, I have carried out a Near Field Measurement (i.e. the microphone is just around 2 feet away from one of the speaker and the mic is pointing directly to the speaker center).

Here is the RTA graph and there is not much abnormal for the speaker.

Anyway, as I said before, I will do measurements again during weekend.

I will try later to measure each of the speakers and subwoofers to see the direct and room response.

Hence, I will turn all speakers off and only measure one speaker or subwoofer at a time against pink noise.

I will make the measurements in front of the speaker (near field) and at king seat (sweet spot).

Hopefully, I can get some useful information out of the exercise.



Some similar setup of direct measurements of speaker and subwoofer using XTZ Room Analyzer.
