Well I got home and played the cannon scene from TIH and set my volume at -20 and I heard the pops. I then looked on the screen of my AVR and noticed that it read "Audyssey Dynamic EQ." I then turned Dynamic EQ off and played the scene again. This time I was able to listen at -15 WITHOUT any popping. For some reason Dynamic EQ was on, but I thought I turned it off when I first calibrated my system.

I then watched the end battle scene at -15 and I heard a quick noise on my sub (which is corner loaded). It came in the beginning of the final fight when the Hulk uses the police car as brass knuckles and hits the bad guy multiple times. He then gets on the bad guy and punches him more. There's one bass burst right as the Hulk lifts his arm that caused a chuffing sound. It was less of a pop and more of a chuff this time.

I then changed the subsonic filter to 20Hz while leaving it tuned at 15Hz. (This is OK to do, based on the manual.) I replayed the same scene and I still heard the chuff, but it was softer and more brief. So it seemed that changing the SF to 20Hz DID help a bit. I even changed my sub trim level from -4.5 to -5.0 and turned down my gain by a hair, but I still heard a brief chuff on that part. I then went back to the cannon scene and was able to listen to it at -13 without any pop from the sub. I didn't go louder than -13.

So it seems now that the only part from TIH that causes my sub to make a funny noise is the end battle scene described above. The noise happens so quick that if you weren't listening for it, you probably wouldn't notice it.

My conclusion is that setting the SF to 20Hz did give me a tad more headroom, therefore I will leave it at that. Thanks for the suggestion. Also, I realized that for TIH, listening to it at -15 is not bad at all. I usually watch movies at -12 and so that has become my magical number to set all movies to. But even at -15, I was happy with the sound of TIH. Perhaps other movies will not provide the same level of sound at -15 and so I'll have to turn it up. Then there are those movies like, The Dark Knight and Ironman, where I can watch it at -12 and hear no chuffing/popping on my sub at all. I guess TIH just has that much more potent bass than TDK or Ironman.

Still, "9" seems to have the heaviest bass of all because I heard popping in multiple scenes and had to watch it at -20 to eliminate them. But then again, I was watching "9" with Dynamic EQ on, which SVS told me to turn off today. Unfortunately I mailed "9" back to Netflix already so I don't have it to test out.

Does anyone know more about when or why or IF Audyssey does apply a boost to some movies, or whether it's only below a certain frequency that it applies a boost? Do you think "9" was getting a boost applied? Or does it just have that much more powerful and lower LFE?

Thanks for all of your feedback! I'd appreciate any more help. But for now, I'll just enjoy the movies that I can at -12, and decrease the volume for the small amount of movies that make my sub pop at -12.

I have dual subs; however, they are on opposite sides of the room and NOT symmetrical to each other or the listening positions. I already have them level matched via a SPL meter at the main listening/measuring point.

I have an Onkyo 605 with Audyssey 2EQ, which only really sets the distance of the subs...and does not apply any sub filters

My plan is to have them both on and run Audyssey. Any advice would greatly be appreciated!!

To solve that problem, you can either buy a device which will introduce a delay to the nearer sub or you can buy an SVS AS-EQ1. I would suggest getting the AS-EQ1. Not only does it solve the problem of varying distances, it also provides an Audyssey filter with twice the resolution as MultEQ XT and the capability to do 32 measuring points.

Turn up the volume/gain on the subwoofer from 11 O clock to 1 O clock. Rerun Audyssey and try to ensure there is no background noise. Let us know what the result is.
Good luck,

Before you go through the trouble of redoing Audyssey what I suggested, can you try 20Hz tuning (all ports open) and 20Hz subsonic filter setting. I also have a suspicion about port chuffing. The higher velocity wind through those pipes (2 for 15hz) maybe a chuffing source. If it is, then the 20Hz tuning with 3 pipes (all ports open) may reduce chuffing. SVS should have designed the subs to avoid such chuffing but with the kind of material you are listening to, you maybe reaching the limits.

Reading 807's thread and also asking there , i have also tried turning Loudness OFF / Preserve THX settings OFF = nothing ,the solution came when i did hard reset(restore ) ,lost all of my settings and started all over again ,First measurement all OK ,sub works fine ,if i try a second one i have the same problem again

Never had that problem with Denon 1909 ,even after 10 Audyssey measurements

That is a REALLY good point in that with the dual subs at different distances, I need to some how incorporate the appropriate delays. Is there a cheaper way for me to do this than something like the SMS? I know I can put in-line delays; however, I would not know how much of a delay to apply.

I have run the setup of Audyssey following the Guide. I put the microfone on 8 differente positions following guide's suggestion but the center speaker has come up with about 6.5db lower than it should. I do not think that is room response because sitting on the main position the lowered volume may be noticed by anyone with a non impaired hearing. It is not subtle. Does anyone have a suggestion? Does this mess up the room correction or should I just adjust the level and let it be?

Thanks,

Michael.

Seems like it is time for you to upgrade from your old 605 to a new AVR that is able to actually correct and utilize your dual subs. With no time/distance correction or sub filter creation capability for 2EQ, you may go to a lot of trouble setting things up and then be thoroughly dissappointed with the results.

And one more point to consider: following the Guide is not enough, it should be strictly followed, word by word.

Good luck to Ya!

Bought a used DTR-6.8 recently and just got it set up. I have a well-treated basement room, very quiet, and I switched off the HVAC system so the Audyssey calibration ran flawlessly.

Source is a new Oppo BDP-83, and I noted some buzzing between cuts when I first listened to the new setup. I presumed it was the sub (Hsu VTF-3), but when I disconnected both the power and the signal from the sub, I could still hear it. Not a 60 Hz hum, not a "white-noise-ish" hiss, but a buzz that was modulated and kept repeating a quick pattern, maybe 5-10 times per second.

Before running the Audyssey setup, I did a reset on the receiver to clear out the former owner's settings, and as soon as I hooked it up, I made sure that I powered it up and turned up the volume to 0 to +4 dB and only heard a bit of hiss with my ear close to the front speakers. This was definitely something that I didn't hear before running the Audyssey calibration.

It is definitely audible from my listening position at ~10 ft when no source material is playing with the volume set at -10 dB, which I find surprising given that I had to run the volume up substantially higher and listen within a foot of the front speakers to pick up any noise.

Went through disconnecting and reconnecting everything a few times, couldn't get rid of the noise. Mistakenly hit the "direct" button on the remote, and it went away...and I recalled that direct mode disables Audyssey. Switched back and forth between "stereo" and "direct", or "surround" and "direct"....in each case, when the Audyssey indicator on the display went out, the noise went away.

Just to confirm, the same thing happens when I go into the EQ page in setup menus and set the EQ to none or manual--in either case, no noise. Each time I enable Audyssey, the noise returns.

The noise is not unlike what I have heard at times from bad on-board audio on a PC. It's not simple hum, hiss, or static, it has a definite pattern that repeats, varies a bit, and then repeats again.

All components are on the same large surge surpressor on the same 20A circuit. The noise occurs simply because Audyssey is enabled, regardless of other settings, or what components are connected to the receiver.

Any ideas? Anyone know if the DTR-6.8 suffered from any of the issues with bad boards that plagued some other Onkyo units?

Thanks!

So is it even better to have the Heights 45 deg to the side and 90 deg (as opposed to 45) up?
