Home Theater IMAX Experience w/ A Robinson-Youtube


Anyone see this tutorial/educational viedeo series on Youtube? Home Theater writer Andrew Robinson has a series of Youtube videos on the subjects of home theater and IMAX Home Theater, where he discusses his opinions, experiences, and recommendations on home theater, HT theory and design, construction ideas, equipment, IMAX experience, technology, and so forth?
Looking for input on what others think of the series, the expressed opinions and suggestions vs your personal opinions, experiences, and competing advice on doing dedicated home theater?
I do find some of his recommendations interesting, but most of the time he demonstrates and suggests that all of this is, ultimately, "left up to your ideas, choices, and interpretations as what choices you make, equipment options and choices you chose for IMAX type of results"!!! Well I find issue with that, and don't agree with many of his opinions, choices, applications, suggestions, and recommendations, personally! Leads people to just do WHATEVER, and expect their dedicated home theater will be as good as anything, or "close enough" to high performance, IMO.
For example: in the IMAX series, he suggests that, since you can do an "inspired" IMAX system, you can pretty much just chose any type of loud speakers you have laying around the house, and they will work just fine!. Also, you can sit as far back and or as close as you like to the screen, and even forgoes the acoustics, from what I could tell!
Thoughts?...

Don't get me wrong...this kinda stuff, at least, does inspire me to want to design "better systems", and work towards putting a better effort foreword in building the very best HT scenarios I can implement. However, I just think that overall impression left by the series is one of "just go with whatever works for you", and it only end's up giving guideposts for "inspiration" for your project, and that all should turn out just fine!
My personal experience, over years of playing with this stuff, is that building a top flight system takes quite a bit more meticulous effort to achieve a quality final product, and that there's a right and wrong way to do things for best results, considering such a wide range of variables people will no doubt encounter. Basically, I find lots of holes in the details given here -or not given - which will, inevitably, hinder good visuals, integration, acoustics, sound and pic quality, practical application, and so forth...without more input and insight, and from lack of knowledge from the users end -All I'm sayin.
If you're gunna use a $2 million dollar IMAX home theater product as a "guidepost" , and clue people in to leaving things "up to you're personal interpretation", I think you're inevitably going to delude people into thinking what they end up with is nearly the same system or performance level, ...which it's probably not.
Zd542, I do think you and Andrew Robinson would make good "Woods mates", should you be lost in a forest! -just go with whatever. (or maybe instead of simply rebutting on my statements, perhaps you could point out some specifics of what's seen on the videos, and comment and recommend in regards to those, no?!)

Lemme make my position real clear... If your average AV enthusiast, hobbyist, or DIY simply picks the ball up and runs with it, after watching these video's, more often than not, the end user's results are going to be poor picture quality and low-fidelity sound quality! PERIOD! Overall experience will be nothing special, in fact, likely lack-luster, at best! ..good results are going to be more involved and knowledge/experience intensive, regardless.,

In case you need me to expound more on my position (no, I don't need to get you a colorimeter and sound meter out to show/tell you what the readings will be! - but guarantee everyone sitting in the theater can easily identify that things aren't so great looking or sounding, and that things could be overall much better, guaranteed!) -What is compromised pic quality, you ask? Um, the black levels are grey, the contrast is poor (with washed out color and contrast, loss of shadow detail), due to white colored ceilings and floors near the screen surface (untreated)! IMAX picture quality? Yes, you'll need 4K projections and processing (source material?), and sitting closer than 40% viewing angle, will require such! -although, yes, some could argue that some JVC,Sony,Panny 1080p's, with their tight pixel structure and processing are viewable at such close distances, perspectively. Still, every other 1080p projection tech will show easily discernible pixel structure, distracting during many instances from a projected image. But make no mistake, IMAX calls for 4K, not 1080p!
What is low fidelity sound quality? Hugh holes (main issue in bass response ) and peaks in the frequency response of the bass, improper reverb and tonality from any given seat in the room, dead/lifeless sound + poorly delineated sound stage, smeared imaging from the soundstage/loud speakers, one speaker booming in your ear on far end seating locations, phase issues, hole in the crossover frequency for mains vs sub from seating positions, lack of dynamics and impact due to improper loud speaker selections, locations, and settings, overall bombastic, uneven, bright in some spots/rolled off in others tonality, and so on.
Also, no, someone cannot simply put loud speakers "where they think they should go", and or chose "whatever equipment they have laying around"-implemented in a given space - and expect great results that will wow their friends, and stand as a reference against anything QUALITY! In fact, enthusiests and weekend warriors have been doing this sort - WITH POOR RESULTS - for years!,...and my experience is they fail miserably in any quality attempt. .. Might as well get a flat screen and a sound bar (in fact, they guy recommends one in the videos!!!) and forget about it! -er maybe some Bose. Whatever works, you know. after All, who's to say your Beats headphones and sitting 1 foot from your computer monitor isn't as good?! ...I always say, anyway. George Lucas would be impress, regardless, I'm sure.
""...Some one actually did take the time to give YOU a quality response??...Electrical properties of Audioquest cables, speaker cable distortions, and mixed bag of claims for well done DBT's????..subjectively crappy car stereo experiences and Bose "Cube"(?) IMAX flippin' theater failings????!!!!"" ..WELL GE!..IM ALL,LIKE,CONFUSE-IFIED!!!
Someone here give me an "AMEN!" -that ALL this contribe chat-spat sounds like a bunch of argumentative forum-room dribble, and decades old flash-backs of Ott and Doc Johnson's "double blindfold interconnect and 12gauge loudspeaker cable testing's, prove no sonic performance difference in audio cables argument!" leftovers from a multitude of timewasting threads gone bye, if you ask me!!? ...MMAAARRVELLOUS!!
Yes, certain AVforum chat-cacklers here,..you can blow off all you like in stating that "there are no realities, facts, or real actual conslusives" for any of this, and insinuate that any typical Samsung Galaxy 5 smartphone's video experience, with Apple Iphones audio, is as good as any IMAX's! -and that, really, none of us Professional AV guys know what they hell we're talking about!! TeerrrRRIIIFIC!
ZD452,I'm certain about one thing..and that's the vast majority of us here (I'm taking liberties) know exactly how likely crap-tastic any system you're going to put together, from your actual efforts are going to perform, and so I, for one, don't personally need to waste my time coming over to your place for any sort of "come over to my place for the demo of a life time system" screening!!..CAUSE I WON'T BE ABLE TO HEAR THE ACTUAL SYSTEM PLAYING, OVER YOUR UNCEASING NON-SENSE OPINIONS!!! -been there and done that, umpteen bazillion times over the years with many other of the opine's on these forums, and I'm pretty sure that NO ONE'S GOING TO BE IMPRESSED! That IS a given, if there ever was one! But you keep up the good fight of spouting more air, and less examples of what the vast majority of any comparing would find a high end experience!!
...in the mean time (I was referring to Bose "Cubes/lifestyle" systems, ..not some custom active high end Bose offering, that no one can get for their home system anyway...nor should they.), I'll just keep on getting REAL MONEY PAID TO ME, for actual REAL quality system installs and builds....cause I know nothing, apparently.
FTR,ZD452, we all think you're cool, edgy and informed! ..of what, I have NO IDEA...
Oh and, FTR,.. gourmet restaurant food, upscale fashion as well as hi-end commuter automobiles are all subjective realities too!!. -you see, cause no one can factually argue that McDonnalds isn't ACTUALLY the best tasting food ever offered, nor is a $100k Mercedes any better than a golf cart, as a commuter car, either!
Point well made sir!...there are no realities. ..It's all merely an illusion. ...at least in your funky world
BRAVO!!
..Do you have a radio show on somewhere I can tune into, by chance?
No no no, ZD542! ..you came to redirect the post, point out that the post was irrelevant and pointless, that no one could ever prove that anything stated is either correct or incorrect, is better than anything else, and that opinions on the matter are relative to ones own opinion, regardless! GREAT!
I do, however, have the right to call you out on your intent! -which was to illicit a response! ..which you did. ..and so I did. ..and so we all did.
WINNING!!!

So let's recap, reflecting- plus from your inferences, as I gather:
-NO, just because 99% of the AV enthusiasts and novices alike will ABSOLULTELY POSITIVELY AND 100% MEASURABLY achieve deficient and horribly low-fidelity and innacurate poor video quality from their audio systems and displays, DOESN'T actually mean that:

1), A huge acoustic hole between satellites and subwoofer DOESN'T really mean that it sounds bad! -it's just more good sound! TRUELY!
2) Just because tonality is drastically different from
seat to seat, DOESN'T mean that you're not getting accurate even good quality sound from the whole listing area!..NO!!!
3), and, just because your loudspeakers are distorting -and
have low dialog intelligibility, cause they're from WalMart -and have no tweeter -DOES NOT mean they aren't as good as
Wilson MAXX reference loudspeakers..YES,THAT'S TRUE!!!
4) when your video display is all washed out and low
contrast looking, with gray black level, it IS IN NO WAY an
indication that the picture quality is not what was
intended from the original source! -WINNING!
5) also, When you use direct firing mono loudspeakers
directly firing next to your ear on a side seating
location, THERE ISN'T REALLY a WAY LOUDER speaker
BLAIRING in your ear, pulling you
completely out of the experience, dominating the sound
n distrascting you from the main soundstage up front!.
ABSOLUTELY NOT!!!..DOESN'T HAPPEN!!!
6) ..Or, when you use any ol 1080p video projector, and sit
2 feet from the screen - and get to see every pixel - it
isn't a sign that you're probably too close, or using
the wrong gear for the job!! -okYES!..THAT'S PROBABLY TRUE
7) or, even though vast majority of people trying to put to
gether a quality system, will in no way use any acoustic
treatments in the toom or sidewalls, to improve sound by
eliminating troublesome reflections, DOESNT MEAN that
the soundstage isn't all indistinct sounding, lacks any
solid detail or imaging, poor microdynamics, lacking
high fidelity overall quality, and doesn't ACTUALLY matter
-Ok, lemme think about that one!
8) Just having your loudspeaker placed behind a perf screen
actually is good enough to make it sound good, regardless
of where the actual speaker are back there, even if you
don't end up measuring anything, or listening first. ..
..NO REALLY, IT'S OK! ..just stick em "yaee wide" and
you're probably good. ..JUST GO WITH IT!..IT'S ALL FUN!!
9) ..when you don't address the sound isolation issues from
the sounds outside, and or keeping the noise from the home
out of the space/room, you really lose anything!..IT'S ALL
GOOD BROTHA! ..don't even think twice about those points!
10) ...anyone's opinion about what is good sound or image
quality, really is OUT OF LINE, and they should just keep
things to themselves, ..CAUSE IT'S ALL THEIR ISSUES,
IN THE FIRST PLACE!!

Yes, ZD542, in the end, ...there really is no need for these postings - nor any real need for this site, for that matter! We're just all here blowing air, and taking up data space on the grid, that is the Matrix anyway!
...WHAT IS REAL?!..WHAT IS REALITY?! ..I always say, anyway
Criderfive, I see you didn't say that you appreciated any of my points of view. Ouch!..that hurts!!

THAT'S IT!!- my $4000 Audio/Video Calibration tool, is now going up for sale on Ebay! After all, no need to measure frequency response or color temperatures of displays - and other meaningless stuff like that - if none of that really matters anyway (or anyone cares, or can really tell the difference, when it's all said and done), right?!

Oh man..I must be in the wrong business.
"As for your lists, I'm really at a loss for words. You're creating responses to fictional statements" (Zd542)

Fictional statements? I'm not making responses to fictional statements. In fact, I'm not making any responses in regards to any statements! I'm mearly making EXAMPLES of what will be completely un addressed, and completely out of whack, when you simply follow the guidelines provided by the Imax Home Theater Experience by Andrew Robinson! No no..THAT'S TRUTH!
I Don't even need to argue this FACT!. I would take 100 out of 100 test guinea pig Imax Theater Wanna Be attempts from this post, go and take my handy dandy $4k meter over, and pretty much nail all the points I listed, to their failings!
That, my argumentative conversing co-horts, IS FACT!!!
So now it's just a matter of whether anyone actually care's about hi-fidelity accurate sound quality or a quality projected image?! If not, we can argue till the cows come home, and you still are listening to and viewing a distorted image and low fidelity distorted sound reproduction. Period...end of your banter...non-debatable, ..just your own view points, after that. Cause they all ended up with nothing special to be proud of...if descent, period. Weeeeeeeeeee!!!! Dunno what else ta tell ya.
