Anyone have this experience? The only DTS title I have so far is Gimme Shelter and, while the DTS track is much cleaner than the muddy 2.0 track, the 2.0 track has a lot of bass and when I play the DTS track there is almost no subwoofer action. Do I have something set incorrectly? What's the deal? I havea panasonic a120 dvd player and a sony 820 htb system connected via coax from Recotron Direct.

DTS sound tends to disregard the "impact" of the LFE channel that Dolby Digital otherwise loves giving off on their dvds.

IS THIS TRUE????
If it is I no longer feel bad about not having DTS. I love the LFE channel. I love having my room shake!

No. It's not.
If the DTS mix has less impactful bass than its DD5.1 counterpart, it's because it was mixed that way, and not because of any inherent flaw (or difference).

But has anyone noticed this on Gimme Shelter in particular? I won't be able to compare until Chicken Run comes in.

Why do people swear by DTS if it has no bass? that's crazy! Glad I have both.

Sonic,
There is NO LFE channel for a 2.0 track. Arguments favoring Dolby's use of the LFE channel are irrelevent for Gimme Shelter in DD 2.0.

I agree w/stevevt:
It's almost certainly how the sound engineers do the mix, not something intrinsic to the DTS or DD format.
I have DTS dvd's that CLEARLY are not lacking in bass when compared w/the DD version (SPR, Dragonheart, U-571, The Haunting). In fact, the latter two DTS recordings have been measured to have THE deepest, loudest bass reponse out of a pool of bass heavy favorites (TPM, SPR, Daylight,...):
http://www.hometheaterforum.com/uub/...ML/028914.html
In the case of U-571, the DTS LFE track is 7-10DB higher tahn the DD LFE track, from 7 to 100 Hz. To make a blanket statement like "DTS doesn't have as much bass as Dolby" is false. It really looks like this issue is going to vary from DVD to DVD, depending on how much effort the sound engineer puts in.
Buskerdog,
Check your receiver's subwoofer/LFE offset level - the "pad" level. If your receiver has this feature (most do), you may have it set too low, e.g., -10db.
Plus, you may have to think about how your bass management is done (crossovers, large/small settings) to make sure you aren't short changing the 5.1 track of bass.

A ha! That's the sort of thing i was looking for. I will check that out. As for bass management, what do you mean by crossovers and large/small settings?

How do you have your receiver and sub set up?
Usually, most people direct low frequency information meant for their other speakers to the sub, since there can be and usually is deep bass signal recorded in the front and rear chanels (on ocassion center).
There are two common ways of redirecting bass to the sub: receiver speaker settings (large/small) and an external crossover.
An example of how you might lose bass signal w/a 5.1 recording: the dvd has alot of rear(center) chanel bass, but the rear(center) speakers don't have a lot of bass extention (100Hz).If they are set to large in the receiver menu, the rear bass can be severely limited by the rear speakers.
Another: the sub is driven off the mains BUT the LFE channel is still on.
etc etc etc
