Might be good for those who are having LFE issues to give the SD-DVD a rent and see if they get noticably better LFE as the poster above did. If so, something may be going on with some of these HD-DVD discs.

i run my left and right speakers crossover at 60hz everything is at 80hz... my fronts are monitor audio gs60 with a parasoun 5250 so they can handle a little lower then 80hz... but i think those tracks are playing well below 40hz anyways... i just don't know i'm gonna borrow a disc from a friend and see if that helps...

I have the same issue with LFE. I know for a fact that it isn't my sub causing the issue, which leads me to believe it is the disk or the player. I know the player works wonders on other disks for LFE so by process of elimination I take it to be the disk. I have an HD-A1 and I use the analog outs. Upon discovering the LFE issue, I decided to run the sound through TOSLINK but this didn't solve the issue. I finally resorted to the PCM/Bitstream Coaxial out, and to my suprise it played back with the bass that was missing using analog. I have a friend bringing over his disk to see if it is a disk issue, but until then I guess I will have to listen to it downsampled to DTS through the PCM/Bitstream coaxial out.

My disk #(340460) NA13127H1R0 01

Has anyone else tried LFE audio playback through the PCM/Bitstream coaxial?

Well, I was a little disappointed w/ the LFE myself. After reading this thread I decided to play around with my setup a bit. Since they never move,The last thing I did was check the crossover and gain setting on my main sub. Crossover was good and volume was good. I looked a little further down and found, to my dismay, that the sub was turned off. I turned it on, played the opening attack and was disappointed again. ...in myself. Ya never get a second chance to make a first impression. The rest of the mix was one of the best I've heard. I heard things on my setup that I didn't hear at the theater. It's gonna be a while before I get to hear that LFE track like it was meant to be heard though.

I've rented the 1 disc dvd version and the bass was also lacking. Sound effects and dialogue was clear but just no LFE. What's weird is that my friend bought the two disc set and I checked out some scenes on his ht. The bass seemed to be stronger.

I think my friend's subwoofer setting is a little higher than mine but the bass different was huge.

I'll test out the HD when the I get back the player from Toshiba this Tuesday. Can't wait.

Add me too on the list of missing bass. I too got up and walked over to the sub and checked that it was on.

I think it's VERY important that anyone wishing to contribute to the thread provide a bit more information so we can figure out what the issue is. Include useful info like: your equipment, how it's connected, your settings, and if the Iron Man trailer sounds COMPLETELY different (i.e. like every other disc you've played before) than Xformers.

Here's my setup/config

XA2 (HDMI out)
Onkyo 905 (HDMI in)
Polk RTI 10 mains/CSi5 Center
DIY Adire Tumult 15" w/750w (this thing goes 120+dbs at 16hz and is pretty much flat response down to that level)

XA2's settings
HDMI auto
Dynamic compression off
5.1 large
crossover (not sure, I'll double check tomorrow)

disk # (340460) NA13127H1R0 01

My 2 cents... from reading this thread, there seems to be a lot of people missing the boat on this. Those that are "complaining" about missing bass aren't attacking the sound design of the film, we're pointing out that something seems very wrong with the sound we're hearing played back by our systems. This isn't a case where it's "what you expect to hear" vs. "what the director/sound designer intended" or if it's "overcooked". This seems VERY similar to the issues that occured with the first release of the DTS Jurassic Park DVD. The bottom line is that the film and the Iron Man trailer sound completely opposite of each other. I'm talking about a difference of questioning "is the sub plugged in during the film" vs. "Iron Man sounds like everything else I hear from my system".

If the disk isn't the problem, I'm wondering if it's some sort of double filtering that's going on? Checking my 905's display, the receiver is being fed 5.1 via PCM during both the feature film and the Iron Man trailer. So, the disk is passing analog into the reciever which means the player is doing all the decoding. That would mean it's getting processed via the settings in the HDDVD player and then the receiver. Perhaps the bass is being filtered into the main channels and away from the sub by the player and then the receiver's crossover is trying to separate out the left over bass in the mains and put it back to the sub?

I'm really curious to get the projector back on tomorrow and tinker around with the settings. I may get desperate and plug the optical or coax in and see what happens when I can get the bitstream directly into the receiver.

FWIW - my system can output infrasonics like BHD's Irene and the Pod Race tunnel explosion with ease, so I don't think it's a case with equipment being the culprit of not going low enough.

Well I know I've already posted about length about this today, but I can verify its not my equipment. Just watched Spidey 3 BD and the LFE was devastating. So curious about what is causing this issue. Will post tomorrow after I try another HD DVD Transformers disk.

In that case, to determine if your disc was messed up you had to look at the numbers around the inner ring of the disc. I wonder if we can come up with something along these lines.

My Transformers LFE is lacking - my disc numbers are:

(340460) NA13127H1R0 01

May be nothing, but it's worth a check.

My disc numbers match yours and I really thought that it sounded great. I don't know it sounded well matched to the overall mix, not overblown, but then knowing its a Bay joint it probably should be overblown

We have a similar setup though yours is newer stuff. I'm running:

360 AO
Onkyo TX-DS656
Infinity CC3
Polk RTi100's
Def Tech BP6s
Def Tech PF15

Like I said my initial reaction was to post that the bass was lacking but the rest of the soundtrack was fantastic. I was just an idiot and forgot to turn my sub on.

hmm

well not sure what to tell you guys.

I had no lack of LFE at all but I run two Klipsch KW-120-THX fed through the KA-1000-THX. From the initial scene with Blackout attacking Qatar all the way to the end. The LFE was low (frequency wise) but it was used constantly especially throughout robot clashes..

Do NOT let the magic smoke out because it is impossible to put the magic smoke back in!!!!

This issue does not have anything to do with the equipment people are using as many who have reported low LFE have extremely capable sound systems.

I beg to differ as way to many variables, BUT

I wonder though. I was using OPTICAL so in essence dolby digital and NOT HDMI/DD+.

Can someone do a switch over from HDMI to optical and see what happens?
HDMI to Analog
Analog to Optical

you know basic troubleshooting steps??

By equipment, I mean the subwoofer in particuar. You seem to be implying since you have "2 Klipsch KW-120-THX" subs that you have no problems. Many who are having issues have subs that exceed yours so this has nothing to do with it. My only point.

There are some parts in the movie where i feel there should have been more bass. Then there are other parts that make my room shake so .. I don't know what to think.

I'm going to try switching to optical tomorrow to see what happens.

I can tell you this though: if this movie requires optical where no other HD DVD does, that is most certainly a disc issue.

EDIT: Tried this just now. Bass is still weak using bitstream of optical to my receiver.

When we listened to this my wife looked at me and said - "I know that you like to hear it louder, you didn't turn it down for me did you"?
Same opening scene with helicopter transform and blasts with low LFE.

XA2 ( fw. 2.5) connected to Yamaha 3800 via HDMI.
I know that the XA2 does not do HBR audio, and might never do it(aurguable).

One thing that I did notice is that when I looked at the details on the XA2 it said "Digital Bitstream" but my receiver only detected MPCM. Shouldn't this have been outputting MPCM from the XA2? Isn't MPCM what the deatails on the XA2 sould say?

I had to move from -20db (reference volume) 0db SW (calibrated with SPL) to -16db and +5 SW to get the appropriate LFE out of the audio.

My Sub is Axiom EP500 and usually shakes the walls. Darla tap on the glass at reference volume is amazing.

I am stumped- is this a disk issue or related to XA2 over HDMI with firmware 2.5, etc?

I rented the dvd version last night and even bought 2 copies at 2 different places and all sound about the same as far as teh bass goes with an advantage to the hd dvd.

Disc problem? No
way it was made to sound... Of course...

Some movies have crazy bass like war of the worlds and hott fuzz but others have so so bass like bridge of teraphethy, ghost rider,300,fantastic four rise of the silver surfer

I would put transformers right where fantastic four is at.


My setup

HD-A2 via hdmi to a denon 2807
Ep 2500- tested to do 1900++ watts here
TC sounds LMS ultra 5400 tuned to 17 hertz and Sub build thread here

and some FR graphs of my setup.

Toshiba HD-EP35 (HD-EP35KE) - low frequencies output problem.

I have Toshiba HD-EP35KE player (region-free + FW 4.0) - when testing this unit with HD DVD test discs Silicon Optix HD HQV Benchmark HD DVD and Joe Kane Productions (JKP) / VideoEssentials DVE HD Test & Demonstration Materials HD DVD + R1 NTSC DVD Combo I found that for some reason my unit is not sending out to the amplifier / receiver (Onkio TX-NR929) any frequencies below 60-70Hz. In Toshiba configuration I am using HDMI out with Auto (full auto multichannel bitstreams for Dolby, DTS and (L)PCM). For other players/sources connected to Onkyo (Funai VHS, Pioneer BD, Pioneer LD, Sony MD etc.) the low frequencies are working as expected. Any ideas how to solve?
