Attack the Block added to poll.  I'll put up Phantom and Bullet to the Head after I get a PvA for them.  Cast your vote!

Attack the Block is in a deadlock between 4 and 5 Stars...vote!

 

Here's an oldy but goody (for its time):

 

Saving Private Ryan:

 

Level - 3 Stars (107.67dB composite)

Extension - 1 Star (26Hz)

Dynamics - 4 Stars (26.22dB)

Execution - A solid 4 Stars.  Great film for its time.  I think the theatrical cut had more to it than the BD....

 

Overall - 3 Stars.

 

Recommendation - Buy it because it is a great film.

Ok, I am now subless and want to start fresh. I am going back to 7.1 and making the room ideal for my 3 front seats And especially the center seat for me. I will add bass traps to where the back surrounds were and panels on the ceiling and the whole front wall. I am also finally going to build a baffle wall and try an IB maybe.

Give me some ideas and which way to go?

Oblivion (7.1 DTS-HD MA):

 

Level        - 4 Stars (111.81dB)

Extension - 5 Stars (1Hz)

Dynamics - 4 Stars (25.92dB)

Execution - 5 Stars by poll. There's not much from 3-15Hz; most of the action is around 30Hz.  It sounds pretty good, and the movie's effects make full use of the rest of the LFE bandwidth, but it's not Gary Rizzo's best mix.  

 

Overall     - 4.5 Stars.

 

Recommendation - Buy.  This is an interesting scifi flick that generally gets you to suspend your disbelief, with a few decent twists.  Although not without some typical Tom Cruise movie plot holes, it's gorgeously and innovatively filmed.  While it likely won't win any Oscars, it's prolly worth a place in your library.

I want to make an IB using a Baffle wall.  I am worried about the wall flexing too much.

This film is riddled by clipping.  Attached is how much.  Clipping is in red.  Channels are L, R, C, LFE, SL, SR.

 

Very impressive PvA, a little something for everyone in it.

Without a doubt I believe the execution would be 5 stars on Phantom. One of the best done audio tracks in a movie, IMO.

I believe there's a new kid on the block to rival all of his predecessors...

 

Oblivion

 

I'll run this one by the scenes I noted in my first look, but I can just about close my eyes, select any chapter and hit play and it will be low end-loaded.

 

Abraham, I don't know what's up with your assessment that the ST is low level. This one put a hurtin' on my room and person.

 

The finale as I heard it:

Both waterfalls look similar.  Bosso, did you pick up on the clipping in Phantom?  I'll audition it this weekend....

Thanks for the heads up, Dave.  Last night I had an issue with some other content being very low level, and went back to my AVR to check settings and, sure enough, all channels were low.  When my Harmony remote spazzed out recently, it must have nuked the speaker levels.  That, in addition to the swamp coolers we use here in the desert, and voila.  7-8dB low "sounding." 

 

I'll edit out that comment from the scoring.  Luckily, this issue with my levels had no impact on the digital analysis of the disc.  I still don't think that Oblivion is exceptional, but it is pretty good and a pretty good movie!

Thanks for Oblivion, that's one of many I've been looking forward to. Not so much wrt the cast, effects, etc, but the premise seems pretty cool. Now, reading the early analysis of the soundtrack it's even more exciting.

Thanks for the graphs.

 

I want to make an IB using a Baffle wall.  I am worried about the wall flexing too much.


I've enjoyed reading your comments as your system has morphed along the way. Likewise, I'd enjoy your take on IB subwoofing too.

Regarding your concern about wall flex; if you employ an opposed manifold scenario, then any concern transfers from mechanical/reactionary motion, toward pressure based movement,... which I suspect would be easier to deal with as the forces are more equally distributed and dealt with accordingly. And even if you went with a straight-front loaded array, the forces .. although quite strong, can be dealt with brute force mass and bracing.

Re IB vs. other approaches ... IMO, the vast majority of enthusiasts would be better off pursuing multiple small-sealed, distributed and employing some sound-field management techniques for optimization (filtering/time alignment). This topic is really dedicated thread worthy, but wth ... briefly ... I'm a conditional proponent of IB, being quite happy with my own results, but it's not suitable for everybody's room and scenario.

De-constructed, an IB is a sealed sub, without the inherent small box impediments (but it brings it's own limitations too). Both of the two theoretical characteristic advantages that IBs possess, 1.) native efficiency/sensitivity in the lowest octaves (and all the secondary benefits related to that), 2.) the large backspace (and how one can eliminate any potential latent backspace energy impacting the driver's output, etc). Both of these entirely depend on design and implementation.

The backspace requirements are somewhat of a continuum between a small sealed and infinitely large. There's many successful builds representing all backspace sizes. Clearly the drivers can overcome whatever any smallish "quasi" IB airspace presents to them. But IMO, there's real benefits to a truly "infinitely" large backspace with clear area immediately around the driver. Nothing jaw dropping, and perhaps quite subtle to many, ... but significant enough to pursue if the overall situation presented itself accordingly.

In addition to the attributes the baffle wall, employing such a technique really elevates the importance of the rear wall's acoustic characteristics. Nothing that can't easily be dealt with, but for a higher degree of post build satisfaction/performance, being mindful of the simple caveats and best rear wall practices would pay off.

Good luck

About how often do you encounter such clipping, and how significant is this in use?


Thanks

FOH,

 

I usually encounter clipping at the -1dB level for some reason (limiters I guess).  This film and a few others have what I call blatant clipping.  Literally running into 0dBFS, and this film does it on a lot of scenes.

 

But if you count the -1dB clipping just as 'offensive', Iron Man and Iron Man 2 are full of clipping (repulsors), and to a lesser extent, Thor.  You then have to think about the desired effect.  Repulsors sound a lot like a jet engine, which will clip a mic (and effectively, our ears, the eardrum and cilia can only travel so far), and the worst clipping (almost straight square waves) are on the repulsor scenes.  So it may be intentional.  When on such a large scale as this, I may think otherwise.  The thing is: Can you notice?  I'll find out tomorrow night....I'm hoping I will perceive it, but that it won't detract from the film.....we'll see.

 

But the answer to your question is "more than I would like".  There are a few soundtracks that are truly clip-free, whether by hard limiting or like Phantom above, especially among loud bass-films, like we measure here...

 

I am expecting Pacific Rim to be a clip and highpass festival.  I hope I am wrong.

Thanks for the oblivion caps. Wanting to see this. Couldn't find it for rent on Tuesday. That's getting harder and harder to do. Won't buy it though.
