I hope you guys can help me once again. I finally got the ASM-2 SPL Meter. Got all speakers set to 75db.
Should I use the meter to test the sub as well? When I try, the sub does not come even close to that. Even if I turn the trim all the way up. I can get it to only about 55db or so. Is the spl meter an appropriate device to test the sub? I never felt like it was really quite as loud as I would like. Also what is the "Weighting" switch on the meter? Thanks guys.
My setup is w22s w150 qs8s ep350 v3 denon 2809ci

Yes, the SPL meter should be used to set the sub, as well. It sounds like something is wrong if the sub is only getting to 55db.
You want to set the meter to C weighting. It's how responsive the needle is. Set it to A and it jumps all over the place with quick readings. C slows it down so it's easier to read.
You might go through all the settings on the sub and in the receiver to see where the problem is.

Thanks. I have gone through all the settings many many times. I simply can not get it to play louder. At this point the only thing I can come up with is that it's the location of the sub. I will have to experiment once I get a long sub cable. Should I have the Response on Slow or Fast on the meter? I assume it's slow.

Set the response to slow. Try playing a test tone through the sub and walk around the room holding the meter and see how much it changes. If it does it may be placement. If not, maybe something is not right?

What are your settings on the receiver for your sub. There will be a gain setting in which you can decrease or increase in your case the voltage from the receiver being sent to the sub which in turn will make the sub play louder.

Well once I changed the weighting to C that seems to have helped. I can now get the sub to play at about 68db, but I have the volume on the sub at 50% and the gain on the receiver at +8. All the other speakers are around 0 on the receiver. While walking around with the spl meter things did not change much.
Also I noticed that when I played actual music vs the test tones the sub is also a bit louder.
In the past I have tried getting the sub a bit louder with and without audyssey on. It always comes down to having to have the volume and gain turned up pretty high. On a few occasions though the sub clipped during movie sequences with a lot of LFE. That is what prompter me to start thinking about an upgrade to the ep500. I would like to first make sure though that it's not something that I may be doing wrong.

Something doesn't sound right. You should be able to get that needle jumping with a moderate setting on the sub's gain.

Are you using test tones or just the "white noise" sound from the receiver..... (which doesn't have much bass in it?).

Good point. I'm using the static noise which the receiver outputs. I just got the Avia disk with actual test tones which I will try using tonight.

If the volume is at 50% adjust it upwards until you hit 75db on the metre.
