Hi,
the response curve of my system baffles me. Can the sudden drop 5k-10k be caused by room acoustics? Too much insulation? The room is quite small 8x4x3,1m. Huge dip in 45 is an obvious room mode, we actually moved the subs and basstraps after this and almost got rid of it.
The system: 18Sound 18NTLW5000 br sub, 2-way tops br 12NTLW3500, NSD1095N + XT1095. I've never used a CD and horn before, but these should go up to 15kHz easily (?).
Any ideas?
Thanks,
-V

Yes, this is the whole system from ~center of the room. I did measure and eq the drivers one-by-one first and it was about the same (don't have screenshots, sorry).
It would only take 1cm for the microphone to be closer to one speaker and further from the other to cause an error like this.
Ok, thanks, I'll check them single and closer to speaker.
In more general sense, how does the response curve look? Like something you might expect in a random room, or very choppy? I've never measured anything with a mic before, so don't know what to expect. It does sound good/ok'ish to ear, but listening position has a lot of impact. We just begun to try things out in DSP and positioning.

It doesn't look too bad for a start.
The room will have an impact but you can't just take a DSP and start fixing what you see. Room problems are more often made worse using that method.
Move the speakers around and try to get smooth bass. Equalising with your processor may work at the lowest frequencies as long as you don't equalise the dips too far. If they're getting nulled you should not lean on them too hard.
Try turning the speakers a little to have an affect on the higher frequencies.
