Rick is correct, that the middle of the room is usually a null area. 1/3 or 2/3 back may be better. Is your sub up front?

From reading your levels to me it sounds like you have it turned up fairly high (9 o'clock is loud for the 500). I run mine between 6 and 7 o'clock, receiver at -7dB (other channels near 0.

Did you calibrate with an SPL meter? The other sub setting not mentioned so far is the phase. Make sure it is not fighting your mains. The easiest way to get this right is play the receiver sub test tone (which is crossed in with the mains if they are set to small) and choose the phase setting that gives you the loudest SPL reading on the meter.

I feel the crossover of 80Hz is ideal for movies with a good sub and setup. 60Hz may be fine for M60s or M80s, but not for QS8s or the VP centers.

Your sub is working right, I mean you should be able to hear it easily when playing test tones or music???

Good luck.



I agree, with the middle of the room thing. I hope I didn't sound like I was arguing. Unfortunatly, that is the only setup we can support given the rooms dimensions and the rooms purpose. It isn't exactly in the middle, though it is pretty close.

My sub is up front. In the corner actually. About 35 degree angle or so from the listening position. I'll try turning it down a bit. It was only so high because I couldn't hear it.

I have not used a SPL meter yet. I need to pick one up. I have always planned to, but i figured I'd do that over the course of the next week or two. But then I noticed the missing low freq. levels.

I think the base is working. You definitly hear it (and feel it) during the tone tests, however, I experience the same issue with music CD's.

For example, I loaded up "The Imperial March". I know from experience the wonderful base that track provides. But it seemed that the percussion section was out on break when I played it.

Another example is during the Universal Logo Opening in movies. Toward the end of the jingle (is this really a jingle?) there are suppose to be a couple of resounding booms... but instead I get a weak thud.

I'll pick up the SPL meter on my way home from work today, and see what it tells me.

Thanks to everyone for the advise and help. I really appreciate it. I'm just frustrated. I wasn't expecting an phenomenal performance right out of the box, but I was hoping for a little more than this.
