Thanks shadyJ, I don't run the sub too often, mostly for movies once a week. I shouldn't be close imo to running too hot....but I just wanted to know if pushing the base volume past the 12 o clock is a bad idea or am I risking ruining my sub? I read a while back that having the volume at 9 should be plenty if not overkill. At 9 the deep LFE in the kung fu panda fight scene isn't even audible...only when I run hot.

The level on the gain knob doesn't men much by itself. It's how strong the incoming signal is. If you want to turn the sub up, use the LFE channel in the AVR. This way you won't lose the calibrated setting within the AVR. I would leave the gain knob at 9'o'clock, and turn the LFE up by maybe 4 or 5 dB. For the most punch, I would run the VTF15h with both ports open and Q set to .7.

Im super happy I added a second VTF15. I set my gain knobs by what audyssey tells me to, once audyssey is complete I do not mess with the gain knob any morebut run them 10db hotter in the AVR menu.

For example, last time I ran audyssey they were set at -8.0 and -8.5. I adjusted them to +2.0 and +2.5

That's great info. I'll give that a try today and let you know how it works for me. I'm currently running the sub both ports open an Q .7. I'm not sure on some of the other settings.

I do use both ports open to get more db's, but I run a Q of 0.3. That offers less db's than 0.7, but the bass is more tight.

Do you have any room correction software like Audyssey? I'm sure it would tell you that 12 o'clock is a bit high.


If you're running both ports open be sure to set it to EQ2.

Right now I'm running +6 on the sub through the AVR and 9 o clock on the volume...It definitely shakes the room

I do have Audyssey and have run it in the past...I always feel that doesn't run the center or rear surrounds hot enough and then I start to tinker. Maybe I should run it again and see what it says.

When I run it, it never sets my center and a couple of my surrounds high enough. What you do then is get you a sound meter. Radio Shack has them and tons of other places to manually set those where you want them.


Read your instruction manual about how to set the sub up to run Audyssey on it. I believe is Q=.7, EQ=2 and keep it around 9 o'clock. Both ports open.





You want Audyssey to set the sub +/-3. I would go for -3 and then leave it. As mentioned above, run it hot from inside your avr settings so you don't lose your proper sub settings on the unit itself.

The 9 o'clock is just a starting point. His room is huge 30'x30'. One sub in that room no wonder he has to it turn up some.

Agreed, that room is pretty good size so I expect a little better than 9 o'clock. Like you said....a starting point. The 15H will be stretched on this one.






EL GUER0,


If you get a positive number, that means you can turn the gain up some but the dial is very sensitive. The slightest movement will send it soaring.

Sorry, I had to go to the fair....I'm going to try and run that stuff tomorrow and give back numbers. I really appreciate all the suggestions the forum members have. Also Prime316 I have the same receiver you do onkyo 809.

Actually you want the sub set to one port open, EQ=1 and Q=.7.


Post 3910 by Dr. Hsu:
Quote:
The rationale behind setting the sub to the different modes is this: We want Audyssey to make the room 'disappear' - equalize out the room effects. To do this, we want the subwoofer to have as flat and extended response as possible when measured outdoors (no room effect). Hence set it to one port open, EQ1, Q=0.7. Once you have removed the room effect, you can enjoy the different subwoofer characteristics of the different tune for the sub - effects of the Q control, extension, etc.
Post 3915 by Dr. Hsu:
Quote:
With Q at 0.7, response is flattest (lower Q rolls off the deepest bass but sounds tighter). We want the sub to be as flat as possible before running Audyssey so Audyssey is just equalizing the room, not the sub. If you set the Q lower before running Audyssey, Audyssey will try to EQ the sub flat and it no longer sound as tight.

Ok, I'm back having completed the Audyssey setup twice...I thought I had done it wrong the first time. I don't know if I'm thrilled with the suggestions compared with how I had it set up before. so here goes:
Left -4 db
Center -5.5 db
Right -4 db
Surround Right -3.0 db
Surround Left -2.5 db
Sub +1.0 db

I watched the Incredible Hulk scene where he hulks out in the school yard before and after calibration. Both times volume at 9 o clock and the volume on the AVR at 65. Pre calibration was a room shaking experience and simply amazing. Post calibration was yet again a let down...I don't think the sub even really registers. I haven't gone back to tinker with any of the settings...nothing is running hot.

How hot should I run my sub using the AVR? someone said +10 db earlier in the thread. Also why does Audyssey make everything sound so mild, sometimes I can't clearly hear people talking from the center because it's quieter than the R and L speakers..which is why i went in before and tuned up the goodness.

also I do have an SPL meter? but have no clue how to use it....is it used when the Audyssey is running or do you play your own LFE material and stand around the room?

I have another question not related to the sub exactly but more aimed at which setting I should watch movies in...there are so many and it always confuses me: Dolby, DTS, blah, blah....can some one help me out with how to choose and get the most out of my system/sub.

always appreciative of your help

What version of Audyssey? Previous versions left me unhappy at times with other speakers, but XT32 does a great job IMO.

As far as the sub, if Audyssey has it set at +1 now, I'd not go to +11 (+10db) at this point. You need audyssey to initially set the sub around -7 to -10db upon completion, so when you boost you are around 0.0 in the AVR menu.

Both my VTF15's are set around 9 oclock, and when Audyssye completes they are around -7.5 in the menu. I then go in and adjust to +2.5.

The 10db boost comes straight from Chad B, who is calibrates both video and audio, and does Audyssey pro calibrations. Ive been so much more happy since boosting 10 db's.

How on earth do you guarantee the sub at -10 db after setup. I always thought audyssey just ran and you got what you got.

Adjust gain knob up to make audyssey dial back (go negative), or turn down to make final setting more positive.

I just run the center listening position then calculate to see what it set the sub at. Once I get the gain knob where it needs to be then I just run the whole setup.

Move the gain up to nearly 10 o'clock and run it, your are guaranteed to get a negative number according to your run at 9 o'clock. The more you turn the gain up, the larger your negative number will get when you run Audyssey.

Is this done before the setup asks you to set the sub to 75 db? Or do I just increase the db to be 85and run the rest of the setup like that?

If your AVR has the on screen db reading when you start setup (Onkyo does on some models), then yeah just set 8 or 9 higher than 75.

I can't run the setup till later as I have 4 little kids that can't be quiet for long enough. I'm on a trip tomorrow till the end of the week. If I get a chance to run the setup again today/tonight I'll post again to try and answer your question. Sorry, I wish I could run it now.

Four kids is 4 too many to run Audyssey. No problem, just run it when you will.

I have "background" noise issues too. That's why I run it at about 4am. I get up at 3:30am during the week so I'm used to it.
