Sanity check: Bad Sub ? (REW Sweep results)

[Kingnoob]

Well, it's an interesting excursion none the less.

Here's an example that I am working on right now. This is Left/Right Q11's. Don't blame it for the target curve (heavy bar with control points), that's me. The solid line (sorry, couldn't figure out how to change the yellow, iut's almost invisible) is the measured response averaged across about an 8' wide stage (it has 17 points). The dashed slightly wider line is how it expects to correct. The bulging to the left of the 20hz is because I checked the "infrasonics" box on the left, for the subs; I am not sure why it is trying to boost the L/R below 20hz, but I can turn that off (I think).

It thinks it can smooth out the standing wave dips and peaks in the low frequencies a lot, and a little for the higher frequencies (those are more EQ treatments, it only does the active stuff below 150hz by default).

Now does this all actually work? That's what I intend to look at after breakfast. But it's not doing something to cripple the low frequency response of the mains, as best I can tell. Now I may be over-stressing them with the target curve and trying to pull the < 40hz up a bit. I'm guessing I really need to move my target curve on the 2nd and 3rd control point to the right.

Now for the subs, it did seem to override what I set. The measured response above 150hz is still there, and I had the curve making use of it (perhaps a mistake), and it decided to prune the corrected, combined response (heavier blue curve) down sharply after 100hz. But it also thinks is has cully corrected out the big dip around 55hz (somehow). I think on the infrasonics area (<20) it is ignoring the curve but just letting the speaker mostly play through, though the corrected is not quite the measured, so maybe it is doing something. But it didn't try to correct nearly up to the curve I drew. I won't be hearing that part though. What's a bit interesting is it thinks it can't fix the dip at about 22hz.

Everyone: bear in mind, this is my first attempts, and I have a lot of reading to do, so I may be drawing in nonsense target curves and have the levels all wrong. My point is that it does give visibility into what it is trying to do with each speaker.

do the new subs sound less boomy ??

They are both cleaner and louder but not boomy if that makes any sense. Except the new subs Audyssey to me is still pretty boomy, I think something in that process ended up too high, maybe some change I made as I was also adjusting stuff, I probably need to rerun it. The Dirac Art is less loud than Audyssey but louder than the old single Klipsh, but is much cleaner in that it doesn't seem to bury the other sounds happening (I love science fiction and somehow something is always blowing up, taking off, landing, etc.)

Though in thinking about it, it's hard to say how much of this is the new subs, or the Q11's that have that really deep base response as well. Both I guess.

Your subs may be turned up too high. Again your best starting point is to play your KEF speakers with no EQ, then add the sub very gently until you feel it is right.

I find that people tend to set subs way too loud. I think because they have paid a grand or more each, they are darn well going to hear them! That is what is known as "over egging the cake."

Maybe not. Maybe it's your lack of experience. Feel right with what material particularly would you suggest? Some people listen to content that have little use for subs.

My receiver always seems to dial subs in hot . I haven’t had a Denon, art seems complex . See some debate if it’s worth it online .

So....ART.... Is it worth it?

Got an email today saying that my Denon A1H now supports Dirac ART and is ready for license purchase. Anyone using art? Is it worth it? Why? Looking for more information... This was supposed to be the cat's meow yes?
