Correct John, the distance of the cone to the walls in the room is what affects the FR. So turning the sub would change those distances, no different than moving the sub along awall a foot and watching the change of FR.

Graeme, you say you are not blown away and have set the sub up acorrding to the manual. Is the sub level matched to the speakers with pink noise playing? if so try adding a couple more db to the level for the sub, but the idea for the sub is to not be 'blown away' but it should just be filling in the lower end the speakers are not good at reproducing. You really shouldn't notice a sub is even on during music only during movies. Well I spent a few hours today fiddling, I have set everything up with the spl and have allowed 5db extra on the sub and 3 for the center. I didn't have anything really decent to play while I did the crawl but hope to get to that later. I have some blue rays coming tomorrow, so I can test it out a bit better. I only had some music to try and test it with today, but I noticed the bass sounds much better in the wife's chair than it does mine, which is only 2 ft away. I found that absolutely amazing. I plan on doing a sub crawl tomorrow and will also try changing the way the sub faces.

As you're discovering and others have pointed out, sound waves are fickle things and small changes can produce big changes. Especially with the low frequencies that the sub produces. I bet an hour or two doing a 'sub crawl' would help out your situation. In my den/theater room, if you stand up in front of the couch near the center of the room, the sub doesn't really even sound like it's working. Conversely, if you go stand right next to the rear wall, near a corner, you get an enormous amount of sub - far overpowering to the mains. But from our seats it's all balanced appropriately. Go rent Master and Commander and play through the opening naval battle. Crank it up. If the pounding of the cannons doesn't knock your socks off, then something is wrong with your setup.

You beat me to it. Most two-channel music is probably not the best way to show off the power of the EP500. I'd be curious to know your impressions after watching/listening the battle screnes in Master and Commander. Also, I am not sure if it has been mentioned or not, but if you room is not large, I would set the sub setting to Full and see if you like it better.

You read my mind, I was thinking about it last night and remembered people here commenting about that movie. I have seen it before but figured I would get it out again to see how things sounded. The last time I watched it, it was just OK nothing to go wow about.
I have the sub set to flat at the moment and have tried it on full and half, but with nothing to really compare to I haven't noticed any change.

If you have not been shaken by the EP500 on that movie after proper calibration, then something is not right.

I did try to convince her that mu seat was a little softer, but she ain't budging But, while she was at work I played some more and ended up connecting my old sub as well, it seems to have evened things out and the base is sounding much better. I still have not had a chance to do the crawl, but as soon as Xmas is over I will try to get it done. Speaking of Xmas ... Have a safe and happy one everybody

Many people end up doing this on January 1st. Audiophiles or not. Intentional or not.
