If you’re not able to find a place in the room where you get smooth bass, both the mid-bass punch and s deep rumble but not boomy then I think it’s most likely the acoustics of your room. I have the same problem as it sounds like you are having. In order to get the mid-bass punch I like for things like cannons and most music I have to turn my subwoofer up so high that the lower bass is overpowering and boomy.
Here is a graph of my EP500s response in my room. Note that the normal frequency response of the EP500 is flat but because of room modes caused by the sound reflecting around the room it looks like this. See the before graph:
http://www.axiomaudio.com/boards/ubbthre...true#Post306124You can see that there is a large peak in the low bass and a bigger dip in part of the mid-bass region. And this is with the EP500 in the best location I could find. No amount of repositioning or room treatments can help this much because these modes will be excited no matter where I put the subwoofer. Just some places are a little better or worse than others.
If you look at the after graph you can see how much flatter the frequency response is. Now I can have both a deep bass rumble and mid-bass punch w/o the deep bass overpowering everything else. (well at least till Charles wants his EQ1 back or Sean buys a “real computer”
).
If it turns out that the room is the problem the best possible two ways to deal with it are to try out dual subwoofers. IMO this is the best option since it should help even out the bass across all seats. Though be aware that it doesn’t always work as in my case of an “L” shaped room.
The other option which I’m using in the other thread is using EQ. the problem with EQ is that is really only works well for one spot. Although some EQ systems like Audyssey (the SVS AS-EQ1 uses a version of it) purport to work over multiple seats they really work best when used only for one seat. Not that they can’t help over multiple seat but sometimes they can make one seat better while making another one worse.
Some people use room treatments but for frequencies 200Hz and below they start becoming very large and also less effective as the frequency drops.
I’m not saying that it’s time for you to consider going one of these routes since I think you could tinker with your setup for some time just to make sure you can’t find a satisfactory position and setting for your subwoofer and receiver.
