Oh, cool, I hadn't thought of that!

Any chance somebody could graph the scene at 46min:42sec of Underworld Awakenings? It's the scene where you first here the Super Lycan roar just before she goes upstairs to battle it and they all look up and the guy say's "what the hell was that". I watched this scene today and at considerable volume. It's the first time something strange has happened. Whilst my subs sounded awesome something in the chain "tapped out" during this scene. Normally I would have the ability to measure SPL but laptop died a while back and haven't replaced yet. Volume is at 70 out of 100 if that means anything. When played at 65 it's fine. Whole house shakes and I would guess I must be hitting around 120-125dB (possibly louder?) during this scene but not sure. Subs run maybe +3dB so a touch hot but again I'm guessing here that may well be +5-7dB. Anyway this scene causes the sound from my preamplifier to drop out then return a few seconds later. I noticed my Crown XLS 5000 (which powers one sub) clip lights don't come on at all. The other sub is powered by a Behringer EP4000 and it's clip lights go on full red for this scene which lasts less than five seconds. I've noticed the clip lights flickering before on certain scenes with the Behringer but without any issue before. Whilst I lose all audio for about three seconds the bass seems to be working during this time (maybe only through the Crown?) in some capacity as the scene is finishing. What an incredible scene! Seems like it's the Behringer clipping causing the shut down of audio and I know the Crown is a better match to the Captivators but anybody got any thoughts? I feel that the scene is close to port tune too around 18-20Hz as it's similar to the Hellboy 2 scene I requested earlier on in this thread.

 

Edit: I will try scene with just Crown running to see if this makes a difference.

 

Okay found the problem, it's my solid state power amp going into protection mode. The power cuts to it and the light flashes just like when you first turn it on then the audio comes back as it clicks back on. It's rated at a genuine 200 watts per channel (seven channels) and I've run things louder than this before so something must be wrong. Cuts out at 65 too now (but not 64). Does it without any sub involvement at all so not the subs. Probably should get another Crown anyway.

 

I would still like the graph of that dynamic scene!

 

Edit: Just checked the SPL using Ratshack meter (forgot I had it!) and at 90dB with no bass involved amp goes into protection mode. Klipsch speakers I use are efficient, 8Ohm load. A 200 Watt per channel Amp should be able to cope with 90dB level I would've thought? Sorry if a bit off topic here direct me to go somewhere else if inappropriate for this thread.

Could it be that your pre-amp is shutting down briefly because you are sending it clipped signals and it doesn't like them?

What are your level trims on your AVR?

Well, I re-watched 9 as planned (although not as loud as I would have liked) - some additional depth that I hadn't felt before, plus it seemed tighter than before - the bass during the Machine's zapping sequences was a series of defined notes and sweeps rather than the general rumble it was previously!

I will have to re-watch Inception as well - that has some slightly weird bass sweeps/notes in it IIRC, so it will be interesting to note any differences!

+1 to that - I might have to rewatch it tonight!

I think it's good to go back and re-watch older stuff, especially following upgrades - re-watching my collection after upgrading from a ported 2x12" to a sealed PPSL 4x18", some of the differences are night and day, and I've only got one of the two sealed boxes in place so far! 

I have now got the first of my two dual 18" PPSL subs in place  so now I need to run REW, sort out EQ on the low end to boost if necessary, then re-watch my entire collection...   lol

It's good to feel some of the lower stuff that was missing on my ported SVS, WotW plane crash scene definitely had content there the other night that wasn't there before, as did the Balrog scene in LotR: FotR this morning before work, but I think it could be louder so MiniDSP or a Bassis from Bosso looks like it is required!

I need to re-listen to it to see if I can notice any, but I'm hopeful too

The audio legend guy who passed away recently (Tom Nousaine??) mentioned the second of the two in an article I read by him so I thought I'd check them out

Ok, this isn't music or a film but please could we add the following to the 'To Rate' list?

Supersonics - Just Jets All Audio

Round Sounds Vol 1, Featuring the Unique Sounds of Radial Engine Aircraft

http://www.amazon.com/gp/product/B000C7P9C0/

I was just playing the first one at -3 with the windows slightly ajar (you can hear the birds singing in the background on the CD before getting deafened by a passing jet lol) then went outside to get something from the car, and my neighbour was outside looking at the sky, saying "Did you hear that?"  LOL

So, my award for most completely unexpected bassfest I've watched this year goes to...







... The Neverending Story.



Yes, the 1984 classic!!

Seriously, I thought I was in for an evening of cheesiness to keep the missus happy. What I didn't expect was crazy bass through most of the film! Felt reasonably deep too, I reckon it goes at least the same as, if not lower than, the 30Hz filtered latest Star Trek!  I reckon c.20Hz peak with unfiltered roll off.

Please, someone pick up a copy and confirm I'm not going mad lol 

(For reference, I watched the English 5.1 DTS sountrack on a UK BD through an Onkyo 818 at -16 with DynamicEQ enabled.  Sub is an equally old-skool SVS PB12-Plus/2 in 16Hz tune.)

Just thought I'd bump this thread as I think Lone Survivor needs to be added, going from the graphs  lol

I take your point lol

There was definitely bass, but it's just hard to know if I'm missing anything as my SVS is 16Hz tune and that would mean I would miss all the 6Hz stuff on Lone Survivor, for example!

I've just had a search here and also on AVS as I swore Iron Sky had been measured (or at least mentioned) before, but seemingly not...

Could we add it to the google docs list, please? 

My feeling is that it's filtered.

Woah, that is going to be a challenge for any system!

Thanks as always!

Nice, that's one to go on the Amazon list

That'll keep you busy for a while!

Will look forward to the results

I'm assuming the mammoths make it?

I'm afraid not, they're all extinct now lol

The quality of 9 really does seem to have slipped past under the radar - excellent story, excellent animation, excellent sound, it's pretty much perfect IMHO

Thank you for your financial and time commitment to this thread!

Oh, and I should be able to post some details/pics of my project soon

I warn you now, I will probably need help with wiring and setup... lol

Bosso,

How well did the Si18's perform? Same sound as the 24?  For the same price you could have 5 of them vs the 24.  Still, it is nice to know one could build a single sub and have it reach reference!  Damn impressive.

I have in my head that the SI 24 is the perfect comeback to a demand from SWMBO that I am only allowed one subwoofer lol

So what's the best way to have our voice heard? I've been occasionally posting that I won't buy certain titles (like The Hobbit) based soley on the high pass filter, but I don't think that really gets anywhere. Are we destined to just accept mediocre results and be pleasantly surprised when the results are good?

I suggested in the 2013 BMotY thread that we

... throw in for a classy "data-bass.com Bass Movie of the Year 2013" trophy to send to the sound studio?

At least that way they could have a little metal trophy on a nicely finished wood plinth with a plaque from us and might pay us a visit online!

X-Men 1st Class: Missile scene

ALVH: Chapter 10

Hey Nube,

The start of X-Men 1st Class, where Magneto is tested in the room and gets angry, may also be quite long, from memory?

Yeah. His stuff is pretty hit and miss. FE will live on as a Sci-fi classic and it deserves it.

 

But... yeah by todays standards it's pretty weak on bass. It did come out in like 96-97' though so that's just how it was.

I know we complain about how some movies are filtered but overall I think we are doing a lot better for bass than even 10 years ago!

9 really is a sleeper of a movie - it sits on the shelf at the store in the cartoon / animated section looking innocent and child-friendly enough, yet it's a very dark tale with sometimes scary moments and tension, and it covers some very adult themes, such as death and loss, challenging authoritarian regimes, war, the dark side of human nature...

The fact that it has killer LFE really makes the film an all-encompassing experience IMHO - it would definitely lack a lot without it!

If you've not watched it or aren't sure about it, get it!

I appreciate the logistical challenges of getting good <30Hz bass in a large cinema room, but I do wish (pray...) that one day in-cinema speakers specifications will actually get below 30Hz
