My sound pressure level meter arrived this morning, bought primarily to set my sub up, for which it has been essential. What I didn't expect was the huge variation in sound level by position and frequency. There are several "hotspots", each frequency dependent. I've now moved my chair backwards by a couple of feet to benefit most from the addition of the sub. Unfortunately there is no practical spot that avoids both the 40hz null and the one at 110hz, I suspect it might be in the garden.... I think the Dspeaker antimode is probably the only cure given the massive dips; as much as 15dB variation across the room.
Have to admit, it sounds fabulous now. Took a while to find the phase sweet spot on the sub, and to make sure it was volume level matched (a lot less than my ears believed to be right) to the 40s. Best £12 upgrade I've made!
