New plot. Moved mags 77" from front wall and 38" from sides. Slightly less toein (maybe 10° fron parallel but I'm guessing). Subs moved correlatively closer to front and sides a few degrees off parallel toward corners.
Gold curve is with the blinds down over patio door black is without blinds.
What do you think?
Bob, a couple things...
Continuing on noway's comment: which mic or spl meter are you using for the measurement? Is the device on a tripod? It's very important that the measurement device be fixed. Holding it in your hand is going to create all sorts of errors.
Also, for now, take your subs out of the mix. Unplug the power cord and remove the RCA connector. Get the Maggies as flat as you can first.
I wouldn't bother with the fluffy pillows or cushions in the corners; rather, I would just buy traps and get them installed (from any of the vendors I suggested in an earlier post). Buy as many as you can afford, both financially and for space.
IF, and that's a possible IF, you get the Maggies and in the right spot AND the bass trapping flattens the response you MIGHT not feel the need to use the subs.
IF at that point you want some extension, then start to read about subwoofer placement - especially material on multiple subwoofer placement.
I
think you've got high-frequency reflections giving you the boost above 5kHz, and you've got plenty of standing waves at low frequency giving you the boost down there.
Also, try moving your listening spot. Take measurements at different spots in the room.
