The Super 8 clip is my goto surround sound theater demo. People love it.

My favorite of the favorites is Finding Nemo. Great surround, great bass, great animation. "Mine!"

That said, I recently had someone over to buy a subwoofer. I played Dolby Spheres, and his wife literally turned around in her seat.
Priceless!

Nah, not to do with Dolby True HD cause there are other clips on the disc also in Dolby True-HD.
I think it is because that Super 8 clip is so heavy on all the channels (also the surrounds!) that it comes of louder as the other clips.
@LastButNotLeast : I changed the volume of the sub from -9 to -5.5 dB. That sounds better to me.
I also have to mention that the clips on this demo disc have more heavy bass (for example : War of the worlds, Flight of the Phoenix, DTS Demo) when compared to the "Reference 2 Bass". Note that the only clip I did not play so far on Ref. 2 Bass is the "Pulse" clip My subwoofer is only a week old, I want to give it some time to settle

I also had some choppy play when playing this demo disc and the Ref. 2 Bass demo disc. Never happened to me on my Oppo-103. Strange thing.

Keep in mind that "lots" of bass isn't the same as "deep" bass.
If your system isn't calibrated, your sub probably has a peak around 40Hz, which gives most people the "wow" factor. If your system is calibrated to flat, the sound is very different.
I used to get "big" sound on the Jericho track with the music when the rocket launchers were turning. Impressive, but not "right." EQ'd, the music is even across the spectrum, and the big "boom" is saved for the landing of the rocket, as you would expect.
See some of the illustrations here:
The New Master List of BASS in Movies with Frequency Charts
I keep bringing this up, but I think it's important, re: Pulse:
The "thump, thump, thump" is cool, but if you can't hear her heavy breathing, feet dragging on the floor, and the rustle of paper as she turns the corner, your bass is drowning out the more important effects of the scene. And of anything else you may listen to. Which is why measurement and EQ are so important.
Choppy play is usually a mismatch between player and brand of disc. I use an HTPC, so I'm afraid I can't offer any specific advice. You may want to look on a thread dedicated to your player; I'm sure people there would have recommendations.
Enjoy!

Yesterday I could not resist to check the Pulse scene out
Seems my recent increase of +3dB was a little to much. Hear breathing and rustle of paper was still audible, but a couple of her footsteps (specially in the beginning when she opens the door) were not audible. So I changed the increase to +1,5 dB which sounded better. It is now at -7,5 dB instead of -6 dB.
Or is it wrong to take this scene as a reference to check the volume?
Thanks for the advice.

Sort of.
There is no real "reference" (okay, technically, besides THX, et al), though, by making that change, you have probably improved your over-all listening experience, which is all that matters. If you have a way to EQ, a boost at 20Hz (or 15, or 10 ) would restore the "pulsing" without stepping on (pun intended) the higher frequencies, but you're heading in the right direction with what you have done.
Which is why I love that scene, just for reasons different from almost everyone else.

No idea if I can EQ.... I guess not with my current setup (see sig) ?
I know the options in my AVR pretty well, I have not seen much about EQ.
If someone can tell otherwise I am happy to hear it

It looks like you have Audyssey MultEQ, which is nice, but doesn't do subs.
See page 28 of your manual:
http://us.marantz.com/us/Products/Pa...oductId=SR5004
You would need (and might be interested in getting, if you want to start a whole new hobby ) this to EQ:
http://www.musicgoroundtroy.com/p/22...inger-dsp1124p
available used periodically (no longer manufactured, but perfect for this use) or something similar,
and learn to use REW:

Or you might just want to enjoy what you have for now.

Thanks for the suggestion Michael!
My T-9 sub only goes 28 Hz @ -6 dB, so I doubt it would be useful to give a boost at 20 Hz or lower
Good advice though, but I think I will enjoy what I have now (for now )
