Any ideas? Sub seems to be lacking....

Living Room Setup

So I spent lots of money on a couple of Axiom's nicest subs, and the other night I put in the most recent Startrek movie hoping to wow my wife with some awesome sound; however, I couldn't help but feel quite underwhelmed/dissatisfied with the low end.

I'm open to input/ideas. I can see both subs working during the movies (sometimes more than I'm comfortable with), but their output isn't providing much thump effect like I think it should. I know I have a large room size, but movie theaters (which are quite large) provide lots of thump. How do I reproduce that?

The link at the top will give you some pics of my room. Let me know what I can do to make it better.

thanks

Have you run any frequency sweeps to see what areas might be deficient?

Well, I've never done it, because I don't really want to know, but basically you get a sound meter (or download one for your smartphone) and a CD of test tones (many available free for download online), and sit there and write down the loudness at each tone. That way you'll be able to tell if you've got a flat response, or a big dip somewhere, and the like. Then you can take corrective action by either moving the subs, recalibrating in some way, or using a sub equalizer like the one from SVS or Velodyne.

Another question would be whether there's anywhere in the house that the bass is really loud. I've got a bass null right on top of my couch...

Do the sub crawl.

Surprising, since you have two subs. Still, it seems like the most likely scenario is a placement issue. Like Ken and Rick said. Get an SPL meter, download some sweeps, walk around the room and see what you see. Hsu used to have test tones posted. Home Theater Shack is a good resource for stuff like that, too.

Watch Inception on Blu-ray with your audience.

Not wanting to seem crude, but if you want more volume from the subs, try turning up their volumes.

Also, try using just the EP800 or changing the phase on one of them.
