30,000 lumens-a-lovin'!

Anybody want to calculate the foot-lamberts you'd get on a 12 foot screen? Screw a gray screen for contrast... just project on the velvet! Or, alternately, go with the silver torus, and wear a welding mask! Thumbs Up

400 lbs too. Makes our CRT projectors seem light!

I don't know 1600:1 CR seems pretty bad, don't care what you are projecting on colors go wacky if its not white. Probably need a hell of a hush box and cooling system too.

Of any digital I would go with an HT5000 if $$$ is no object.

Mike,

I don't think Perisoft or anyone else is suggesting that thing for HT - that would be beyond stupid. First of all, as Mike mentioned, the contrast ratio sucks. Next, the thing draws 8400w. Wow.

Still, power draw isn't the amazing thing - this is: Dissipation is rated at 25100 BTU/h. Shocked

I could literally heat my house with the heat dissipated from this machine. You would literally need a separate A/C zone (with serious additional cooling capacity) to cool the equipment ROOM this thing sat in. A hush box would not only be impractical, it would be nearly impossible since you'd either have to have a super-cooled air supply (which would be bad) or a super-high velocity (which would also be bad).

But, on the plus side, it looks like it's all set up right out of the box with edge-blending capability. That's cool! It is also designed with physical mounts for stacking two projectors. Can you imagine STACKING a couple of these things?

Retail is $127,500, but these guys have them listed for $106,999:

Unfortunately, that's without a lens, lamp or mount. With a lens ($7500), lamp ($1250), a mount and shipping, the total comes to just over $117,000. Hmmm... Now, where'd I put my damn Amex card?

Smile

Damn, I wonder what the Yahoo percentage is for that online store for a sale that size?

The HT5000 would probably also be my choice if the money stork dropped a bag at my house. In fact, I'd probably just duplicate Art's whole projection setup. Of course, I'd need a new house because a 14-foot scope screen literally wouldn't fit in my basement anywhere with enough throw to actually project anything on it.

Oh, and brightness...
- A 12 ft-wide 2:1 screen would have 72 sqft.
- 30000 lumens / 72 sqft = 416 fL on a 12' x 6' 1.0 gain screen

Smile

Yes, completely insane.

Now, to work it backwards, if you were shooting for 20fL (hey, why not?), then 20 = 30000/x. x = 1500 sqft, then. So, we could go to a 50'x25' screen and still have 20fl... at screen gain 1.0. More likely, you'd project on a 30-40' wide screen and have over 40fL to compete with a bunch of ambient light. These two scenarios are what this machine is really designed for.

I'm sorry, Dave but your post is just pure bull****. Art LOVES film. He and his wife love to have friends, family, etc. over to the house to watch movies. They love to entertain. Further, he's a true enthusiast. Is some of it bragging rights for him? Maybe, but that's what makes this hobby and so many others fun - the quest to find and obtain the very best you can with whatever resources you have available.

What about seating? What if you have lots of friends, family, and like to entertain? I don't think a theater like Art's with 13 seats is in any way excessive. Could he have "gotten by" with an RS2 and a 10' wide screen? Maybe, but then wold that have been much of an upgrade over his 8' screen? In my opinion, no. I'm serious - until you sit in his theater, and see that 14'-wide scope screen, you just can't imagine it. And 720p would VASTLY inferior to his machine, and IMHO totally inadequate for that screen size.

By your logic, why on earth would anyone ever buy an F430, Murciélago, or Saleen S7 when a Corvette ZR1 or even a Z06 would offer most of the performance at 1/5 to 1/10 the price? Hell, why would need to buy a Saab, when there are some nice domestics which offer most of the performance for less money? Why do you have a more aggressive performance-oriented Saab - would that be big dick bragging rights? Or, is it just because you're an enthusiast?

Assuming a guy is already doing whatever philanthropy he sees fit with the money he's earned for himself, there is no damn reason he can't spend it on whatever he pleases - whether you think it's "unnecessary" or not.

You completely ignored my references to your Saab. You could easily drive a much less expensive, but similar performing car and in doing so would be able to donate a good chunk of change to "dying kids or other moral issues." Yet, you didn't. You chose to use your resources to buy a fast car instead - which clearly shows where YOUR priorities lie. Then, to top it all off, you denigrate others spending habits and rationalize your own by talking about "diminishing returns". Please.

Could you explain to me how you're not a hypocrite?

Hell, I'd be happy to have ceilings that high to work with. Laughing

Mike,

In my room, the scenario you present would be PERFECT. Right now, my 96x54 makes scope stuff maybe a little on the small side. Not bad - just a bit small. 16:9 stuff on the other hand is a little too big vertically - especially with my low ceiling. A 9' or so CIH setup would be perfect, because it would make the scope stuff a little bigger, while making the 16:9 stuff a little smaller.

I would do a 9' CIH setup in a heartbeat if it didn't make things so damn complicated and/or much more expensive.

I forgot to post this this morning. Here's the power connector on this big SOB.

If you've never seen that style of connector, that grey square outline is close to the size of a double-gang switch plate - probably 4 inches square or so... You could probably almost put a baseball inside the blue or red sleeve if the connectors weren't there... Just so you have a feel for the scale of this thing!!!

Shocked

Hey Dave,

In the words of my favorite deceased relative who always drove very basic vehicles, "when I want to show off I take them to see my plane".

Be willing to bet that Art employs more folks than most Americans. I would also guess that the construction of his incredible HT took the work of many skilled tax-paying personnel.

I'll bet he also pays property tax on the sq. footage of his his HT!!

Don't know if you have been to Michigan lately, but a tax haven it ain't!

Getting back to the original topic, I envisioned the 'auxiliary nuclear' scene from Christmas Vacation when I saw the power consumption of that beast.
