Listened to "days are gone" from Amazon. At the beginning Bass seemed fine but after 30 secsonds the section sounded as if Bass wasn't as clear. It was impactful and I could hear the low frequency imactp but it didn't sound very clean. Does it sound very clean in your system? I think I"m getting good check slam from my mains instead of my subs.

Think about what you just said. True, music doesn't have a LFE track. But bass management combines LFE with re-directed bass and outputs it all to the same sub channel. Your sub has no way of knowing whether the bass came from LFE or from the redirected signal.

What may be different is that the lower the bass signal, the more likely room modes at very low frequencies may be coming into play. This would happen whether the source were movies or music, and whether it was LFE or re-directed.

You should not be getting any slam from the mains at all. Frequencies below the crossover should be going to the subs, and the mains shouldn't be getting any of the low bass frequencies.

Unless, of course, your mains are set to Large, or you have "double bass" configured. If either of these are true, we would be getting closer to understanding what is wrong with your bass.

nope nope. Mains were set to small. It was just a guess that that mains are producing good mid-bass to cause a good check slam. Thought, after reading you post, I set mains to Large to see how it does and it has punchier bass. May be 8dB is a bit too much? May be I should recalibrate Dirac. I had to move sub and it might be caueing it. FR doesn't show it but oh well. I do have a Dirac question. I"ll post it on 88-a thread. See you there Jerry .
