Not to get too far OT, but if it's calibrated, the power and efficiency shouldn't matter. That would affect your ability to reach (or even exceed) "reference" levels (which, IIRC, is 105db peaks at the seats from the satellite channels, and 115db from the LFE channel), but the reference is still the reference. If you calibrate a -30d test tone to 75db, then set the MV reference to 0, that should eliminate the variables of speaker efficiency, amp gain, the room, etc. Of course, it's not perfect, because some systems may have some compression (or just plain inability) that prevents perfect scaling to 105db, but at least you know contented encoded for 75db is 75db @ 0MV, and things should scale from there within your system's limit.

That is exactly what I did was turn the test tones down. MV at 0 is still over 105 db's peak, well over actually. It was supposed to be 0 for reference but it did not work I guess. When I get out the spl meter 105 db's peak are at around -15 MV on some movies and -13 MV on others. It should be 0.

You could lower the trim levels for each channel so 0 dB becomes reference. However, this way you will lose maximum potential volume headroom. On my home theater, -5 dB is reference.

All my channels are set at 75 db's and 0 MV is past 105 db's peak, more like 120 db's. The trim goes to -20 db's on all channels and I am there.

it seems that u guys are playing with numbers to get ur reference at "0" MV

arent u supposed to have all speaker levels set at 0dB when you first run your test tone and then you add/subtract to get all speakers matched at 75dB via splmeter.....

I enjoy my movies also at high volumes.... but movies like Mr.and Mrs. Smith I cant even attempt to watch at close to reference... I have to watch it at -40dB MV without be annoying to neighbors.....
my reference is at -16dB MV...

I did play WAR OF THE WROLDS at almost reference level and both neighbors came outside wondering what was going on

Not necessarily. The "MV" level at which Dolby Reference Level is attained can vary because different receivers, speakers, and rooms all have an effect. Different receivers use different "MV" scales (some go from -80 to +16 or so, others go from 0 to 70 or 0 to 100 etc). Speaker sensitivity can impact how hard an amp needs to work to achieve a given output level, which also affects what receiver MV setting will be needed to achieve reference level. Finally, a larger room will require more output and more power to reach the same levels as in a much smaller room, against skewing the "MV" setting needed on a receiver to achieve reference level.

I used AVIA so I calibrated to 85dB instead of 75dB, but yes, I set speaker levels to 0, raised the MV until I reached 85dB ("reference level" according to AVIA's test tones),then level matched via SPL meter so all speakers read 85dB. This ends up being about -2dB or -3dB on my receiver's scale of -80 to +16.

Assuming your reference level really is -16MV, you watched Mr. and Mrs. Smith at -24dB from reference. Most people here would classify that as quite modest. I usually listen to movies at somewhere between -8dB and -3dB from reference level. Of course I don't worry too much about neighbors either because they can't hear my HT very easily . I don't know what I'd do if I lived in an apartment...

Any idea what kind of peak bass levels you were reaching there? WOTW DTS is recorded a good 5-6dB HOTTER than normal for reference level, so if you watched it at reference you'd probably have LFE peaks of 120-125dB (assuming your subs are calibrated flat - if they're hot it would be even louder). Very few forum members have subwoofer systems that can easily deliver 125dB peaks in LFE - most of those bass nuts are in the DIY forum

i did test it out and obtained a peak of 98db at the seating area from the lightning that happened just before they ran into the house.. but this was recorded using a dgital splmeter and the MV was at -30db 14db below reference.. i know i posted it here somewhere.. i just did it last weekend..

forgive me for such a noob question... but does the format make a huge difference? I ask because I recently set up two ULS-15 and have been trying to find some test material...

I have not bought any BRs, I usually just rent them, but I do have a fair DVD collection but waterfalls that I have tried, (LOTR Two Towers, Matrix, Sum of all Fears, T2, T3, Unbreakable etc) are really lack luster. I had a friend who came over with Transformers on BR and the flip scene was just insane. So does the format DVD, BR, HDDVD make a huge difference, or is the flip scene just that insane that it put other waterfalls to shame?

as far as format, some will say it makes a big difference and some will not think it's a giant difference

some movies you might want to try are war of the worlds (the one with tom cruise) and cloverfield (and some others, scan the thread and the forum). the newer movies definitely make a big difference no matter which format. they keep raising the bar on the LFE channel

try Cloverfield on BR and Master and Commander on BR. both awesome for bass.

I am calling it now, The Unborn movie that comes out next week has a few LFE suprises. It might give WOTW a run.

Totally one of the best chapter's in HT. The lightning hit 116 db's for me at 14 feet. At -8.

I didn't see this movie on the ratings page. But, if you haven't watched 28 Days Later on Blu Ray...your missing out. This movie totally, completely hammered from start to finish. I would score this at least 4.5...

I just saw the trailer for The Hurt Locker last night.

Oh yeah baby! When the movie's plot revolves around experiencing large explosions at extreme close range, and the trailer shows clips of the gound heaving, ... you just might have a BASS winner.

There were at least 4 extended bass scenes in the Knowing. The biggest bass was when the blonde guy opened his mouth and the light came out. That was intense. Every catastrophe, that open mouth scene, and when the boy looked out the window.

I still think the biggest wow factor in The Knowing is when that guy opens his mouth and the light comes out. That had everyone's hair standing up and pants flapping from 18 feet away. It was not expected.

I agree with MK. I just finished watching The Knowing, and when the blonde guy opened his mouth, the result had me screaming Oh My Gosh, laughing, and applauding the BASS. Fantastic.
