There’s not much to tell really. The only thing the waterfall will tell you is if the bass traps have been effective. That will require two measurements in the room: one before the bass traps are in the room, and a second one after they are in place. This “before and after” method could also help you determine the best place to locate the traps, but I think the corners of the room are usually what is recommended.but....if this measurement is correct, can you tell me what can you see inside it?
Yeah, the discrepancy was so huge I just assumed the measurement was for some full range speakers. You may be right though; we’ll see what Allesandro comes back with.It appears to me that your front speakers are set to a much higher level than your sub.
No, I mean if you want to compare before and after graphs, it’s helpful if they are both taken at the same SPL level. If not, the one taken at a lower SPL level “looks” better than it really is. If not, you can always offset the data to make the two readings match, as Bill suggested.for Wayne : when you say : "It’s “lower” because the second reading was taken at a lower SPL level."
do you mean i take the measurement at a lower "volume" ?
