Question to Q7 meta owners
Hello,
I'm a owner of a pair of Q7 meta since some months and have noticed two problems in my pair, so I wanted to know from other people that have this model if this is normal behavior or not:
1) when doing measurements with sweeps for room correction, I've noticed a cabinet resonance around the mid bass/low mids (think 250 to 350 hz) that make the cabinet make a "farty" sound. It happens only on my right speaker, so I think this is a defect. Further testing with steady tones revealed that it does indeed resonate, and if put a hand on the top of the speaker and push down from above, or push on the drivers rubber rings, the resonance stop. Is this expected since it's the budget series so the cabinets aren't perfect, or should I contact kef? It doesn't bother me in listening but still.... This happens at safe levels, I run sweeps at an spl of max 78/79 db
2) imaging depth in very open reverby tracks cause a very disconcerting effect. The sound is very 3d and moves left and right, forward and backward, and open spaciuously upward too, which I like, but in tracks with very large reverb the forward extreme get behind my head, so the stage has a front part with bass drums etc and a back part that seems to come from behind me.
The soundstage is like a cone with the apex behind my head. Sounds that should be placed back localize between the speakers about a meter behind them, and the full stage there is a semi circle about 3m wide, with panned sounds coming from just a bit outside of the speakers. The frontal part of the stage localize from ear level to behind the head, and it shrinks in width compared to the front to about 1.50 m around me sounding very headphone like and literally placed forward compared to the front. It is most prominent in drops in tracks where there is a lot of reverb and spatial effects.
This is NOT an effect of the tracks. Other system I had didn't reproduce the stage like this, neither do some fairly decent pairs of open back headphones or iem I have. It isn't a back wall reflection either, as my backwall is 8 m behind the sofa and for all intent and purposes it's like it isn't there. Maybe it's the ceiling reflection? I have high 3.15 m ceiling, and the ceiling reflection is the more prominent in Etc. Still, it's 17 db down from the etc peak, which puts it almost at studio standard levels, so I'm not sure it's that either. Speaker placement is a perfect 60° stereo triangle. Speakers pointing almost straight forward, toed in toward me around 10°. Tried other degrees of toe in and placements in room and it always happen with very open stage tracks.
I love the speakers 3diness but this behind the head sound with every track with a bit more reverb is very annoying and disconcerting. What might cause this? Is it just the kef sound, or is there some type of problem? Might problem 2 be related to the problem 1 resonances?
Thanks
