Question on room dimensions

gmcman

I've had my 2B's on the narrow wall since I've owned them, just isn't practical at the moment to put them on the long wall. I think I may be able to try the long wall now, but with the room being rectangular.....roughly 28'x13', would the 13' be too short for the rear reflections?

If I can get it setup, the couch will be on the rear wall, and the front of the speakers will be about 12 to 13' away, but with at least 10' on each side instead of 3 1/2'.

Ceiling is 8' as well, would this be ideal or less than ideal?

The long wall would be the preferred. However, with the speakers 8 feet apart I think you'll find sitting 12 to 13 feet back might be too far away, but you never know. You can always play around with the distance apart until you find the sweet spot.

I should be able to keep the speakers about 6' apart, prob 7' max. I guess my main concern is my head about 1' off the rear wall for normal listening. The sweet spot would be closer and that's fine....I don't know how the SDA would be affected by a closer rear wall.

Right now the right speaker is 2'8" from the wall and the left speaker is 3'2" from the wall....and with 22' from the back wall.

I'm afraid to ask this but, my speakers are currently 4' from the rear wall.....does this just diminish the bass or completely kill it? Does the speaker just lose all tonality at a certain point or am I still ok just with reduced low bass energy?

The reason I ask is I want to say there's a small void in the mid bass, almost a dip near the 500 Hz area. I haven't done a REW sweep lately but that's the best guess. seems any material I listen to has this issue so maybe it's the speaker placement.

The wall it's on now I can't push them back, if that is the case though then I will definitely relocate them elsewhere and just figure out the furniture later.

The back wall normally provides bass reinforcement, to a point. Different speakers react differently. Some improve, while others become boomy when placed closer to the wall. Experimentation is the only way to fine tune the bass in that room with those speakers. Put them in a different room, or on a different wall, and everything changes again.
For SDA's interaural crosstalk cancellation to work, an equilateral triangle is recommended. That doesn't mean it won't work if the speakers are closer together or farther apart, or your listening position is closer or further away. Try to get as close to an equilateral triangle as possible.
