Some questions if you all don't mind.
My pair of 8341s are approximately 60cm from each sidewall (small 10x11 ft room) and 30cm~ from the front wall, and 130cm~ from the listening position. I use them with the 7360A placed offset slightly from the centreline of the room. Surprisingly I have no issues with the bass post room correction in this configuration.
I've been using the speakers in vertical for a while but there are some mid-range nulls due to the side wall (I tried placing 4.6'' GiK bass traps directly behind them, on the back wall, on my desk and under the speaker and none of these positions had any positive effect). However, when I treat the side walls with two bass traps each to alleviate this, the liveliness of the speakers suffer greatly: that is to say they become point-source like and fatiguing to listen to, although the imaging clarity does improve.
So boiling it down:
- Is my side wall distance and/or front wall distance bad? Should I narrow the triangle and listen more nearfield?
- Would placing the monitors in horizontal reduce issues with the sidewall? (I don't have the stand plates on hand so cannot test myself)
- Treating the sidewalls seems out of the question for my subjective listening enjoyment and the front wall corners are already bass trapped. Should I aim for more back wall treatment or look into ceiling treatment?
