Re: Audyssey Graphs - Please post your results!

I realize this thread is pretty much dead but my latest subwoofer measurements are below. Taken with REW and a UMIK-1 calibrated from CSL. MultiEQ XT seems to do a pretty good job. You can also see the effects of dynamic EQ at this SPL level. I have noticed that Audyssey applies gains and cuts and will also adjust the overall sub level. It also seems to increase THD significantly (as measured by REW). Maybe all eq does, not sure. Sounds great nonetheless!

Re: Audyssey Graphs - Please post your results!

Not sure if this is the place to post this. Im very new to the whole REW thing, just got my UMIK1 mic and set it up on a Macbook. I measured at the main listening position, but have no idea how good (read bad) the graph is that i ended up with. This is after running Audyssey on my Marantz SR6008. I have an SVS 12NSD in my living room, so there are no room treatments etc, its just a regular rectangular shaped room.

Re: Audyssey Graphs - Please post your results!

Still working on the 41 Hz suckout, but subs placement possibilities are limited, so it's phase, distance, volume settings and direction only :/. I like the sound though, which is kind of what matters. DynEQ is on, -10 dB reference level offset. Target settings with hard knee house curve and 1,5 dB/octave rolloff @ 1 kHzAudyssey Graphs - Please post your results!-snap-15.jpg

Re: Audyssey Graphs - Please post your results!

Let me know how solve it. I have a 60Hz hole unless I open one of the double doors which moves the hole to 50Hz. Go figure

Re: Audyssey Graphs - Please post your results!

Here's our current graph.

Two Rythmik FV15HPs attached to a Denon AVR4520CI using XT32/SubEQ HT room correction software. Each subwoofer is equipped with a PEQ that allows each sub to separately EQ a particular frequency or bandwidth. One subwoofer is placed directly behind the MLP and one is placed on the opposite wall across from the MLP.

Usually it's caused by a two reflections (primary and secondary) running into each other. And usually, the offending wall is the one directly behind the MLP.

Where is the door located that changes your null from 60Hz to 50Hz and what happens when both doors are opened?

Offending wall is 10 ft behind MLP (see photos). Both doors open creates large nulls at 60Hz & 80Hz. I am holding off posting REW plots until I measure the Audyssey results.

Re: Audyssey Graphs - Please post your results!

It looks like the receding wall angles on the double door area are what's causing your room fits. From your image, it's looks like you have an angle on the wall of the equipment rack and then at the door.

What happens when you place a Depth i below the equipment rack?

Re: Audyssey Graphs - Please post your results!

Full range with subs obviously quite hot. I assume this looks pretty bad? Also 0-200 to show subs.
