Yeah, but I think that's the big risk (and a pretty common occurrence) at manufacture owned forums. You get a bunch of like-minded folks...

Funny you should say that...the conversation with my wife started off with, "Dear, I need your help with something pretty annoying..." All we did was put the sub upside down (i,e. firing toward the...

We know that two vendors have products waiting on Dirac, both of them past their initial estimates. I don't think the problem is the vendors.

The sub needed to be at ear height, and the mic needed to be at driver height. One of the reasons I'd avoided doing this previously (other than the fact that I didn't want to pick up 100lb sub and...

Keep in mind, by the way, that ~ every 10dB increase you're doubling perceived volume. So by 30db increase, you've gone up by a factor of 8! Your sub is overpowering your center channel.

Edit:...

In that graph, your bass is 25dB to 30dB above your center channel. I take it this is still with the 3 and 4? Channel 4 is already 10dB hotter than channel 3, and you're adding that to the output...

Since he's able to send a signal to individual channels, I'd recommend just using channel 3, and disabling processing.

When you run a sweep on HDMI channel 3, unless you turn your sub off, the crossover will take care of routing bass where it needs to go. As far as the target goes, I believe you're referring to the...

Also, I'd like to see the full frequency sweep if you can. The slope that's moving at is pretty sharp, even after 100Hz. It can't possibly keep up such a sharp decline.

That looks better. Your sub looks 10dB hot. Are you measuring HDMI channel 3 alone, or channel 3 and channel 4 at the same time? If you're measuring channel 3, try turning down your sub a bit. If...

Can you adjust the scale (maybe 40dB to 110 dB) so we get 5dB increments? You've got a house curve that drops you 25dB between 40Hz and 20kHz. That's pretty aggressive. I'm not sure it's wrong,...

I went from right behind my seat to the front of the room between my main speakers. It's not centered on the front wall, but rather about a 3rd of the way down the wall.
