I turned the subwoofer gain to like 2 o clock, ran the YPAO again with angle setup and multi-position just like this website suggested:
these were the results of my 5.1 setup in a 15x15' room. Subwoofer=-4.0db, FL=0.0, FR=+0.5, SL=+1.0, SR=+0.5, CEN=0.0. Angle (horizontal) Front's = 18degrees, Surround's = 100degrees. All 5 speakers were manually set to small and 80hz after YPAO ran.
I then turned the subwoofer gain all the way except 3 clicks. I also raised the center manually to +3.0.
Still can't feel the subwoofer like I would like. What's the next step, I have a subwoofer trim in the Yamaha options menu "Subwoofer/Bass" I increased it to +3.0. There is an extra bass button in the same menu, should I turn that on? What about manually increasing the -4.0db setting in the YPAO results?
I really don't want to return this sub since everyone says its so great.
I have several observations. Let's start with the subwoofer position. You said you tried the two front corners and that the subwoofer sounded louder there. Louder is what you are after. Then, you said that you assume that the louder sound from the corner is the "boomy" sound that you don't want from a subwoofer. I would not be so quick to make that assumption if I were you.
A corner location can make a subwoofer sound somewhat boomy, in some cases. But, that is a YMMV determination, not a rule. In many cases, corner locations work just fine. And, if a subwoofer is getting a little too much boundary gain from the two walls and floor, it is always possible to move the sub just a little out of the corner or to angle it in a way that reduces the boominess. This is just trial-and-error to find a location where the sub sounds louder, without sounding boomy to you
. And, you may have to move it just a little, as described above, until you get just what you want.
So, the first thing I would do is to try the corner locations again. Please understand that if you sent the PB2000 back and bought a subwoofer that was three times as expensive, and three times as powerful, good positioning in the room would still be equally important, and a corner location might conceivably still work best. (If you are specifically looking for more chest punch, as described below, you might also try placing the subwoofer very close to your listening position.)
Second, are you still you looking for more mid-bass? When you say that you can't feel the bass the way you want, are you talking about chest punch? If so, that is mostly a matter of mid-bass volume, but you also have to play content with percussive sounds in the mid-bass range (~50Hz to 100Hz for most people). Examples of percussive (abrupt/sharp sounds with some impact) sounds would be a kick drum, or a loud bass guitar chord, or a gunshot in a movie. But, you won't feel that chest punch all the time, no matter what. It will take the right content and fairly high volume levels.
My third observation concerns your gain/trim levels. If you set your subwoofer gain at 2:00 and only got a -4 trim setting after YPAO ran its auto calibration routine, then something seems off to me. How big is your room, and is it possible that your listening position is near the mid-point of a rectangular (or square) room? If your listening position is near the mid-point of the room, it is very likely that you are getting some cancellation, and that cancellation could definitely be affecting your subwoofer volumes.
In any event, I think that you are dealing with a subwoofer location problem. Unless you are in a very big room, and located a long way from your subwoofer, a 2:00 gain setting should have given you a lower trim level than -4. So, check to see whether your listening position is near the mid-point of your room. If it is, you may need to move the listening position backwards or forwards by a foot or two. And, try locating your subwoofer back in one of the corners. Then, we'll see.
When you re-calibrate, aim for a trim setting of about -5, or -3, after
you have raised your AVR trim as much as you want to. You don't want your trim control to be much higher than that in order to prevent clipping. And, it is important that you make most of your volume increases with the subwoofer amp, and not the AVR amp. As noted in an earlier post, the PB2000 will not be able to hit its maximum volume levels unless the gain control is at about the max level. So, if you still have three clicks left after you rerun YPAO--use them. Raising the subwoofer volume in your Yamaha will not
give you the same results.
I hope that you will try these suggestions, and I hope that they help. After you have tried these suggestions, you might also want to tell us what kind of speakers you have, and what your speaker crossovers are after you run YPAO. There may be some suggestions that can be made there that will help. Getting good sound quality and sufficient bass in an HT system starts with good equipment. But with subwoofers especially, good placement and the appropriate use of settings and adjustments can make a lot of difference.
