I looked through the manual as well, and I didn't see that specified either. Thanks for the input. I've played with that calculator until I was afraid they'd ban me from the site smile.gif I never got it to tell me what I wanted, though. 30' throw with 25 uncalibrated f.l. biggrin.gif

I may just have to pony up for that A-lens right out of the gate........... Decisions, decisions smile.gif I suppose if I start looking for a used 6020 now, I might get lucky and save enough to cover most of the cost of the panamorph.

Yeah I agree those are some purdy glasses.

I do prefer my ladies in contacts though. Here are the RTROSE groupies to salute you in making the grade for passing your inspection.



On the projector front, I'm an Epson fan and after seeing Vik's 6020 I would not hesitate one moment in getting that beauty. Very nice indeed. Bright and sharp. I have the little brother 8350 and love it as well. The 6020 is much nicer than the 8350 though.

Congrats again on the pass.

Regards,

RTROSE

As a point of note, the 5020 and the 6020 are absolutely identical from a performance perspective. The 6020 has a black cabinet, an extra year of warranty, includes some 3D glasses, gives you an extra bulb plus a few other value-add items. The bummer about the 5020 is that the cabinet is white. So you can either remove the cabinet and paint it...or build that hush box you were intending to build to conceal it.

The point is that you can get the same picture quality with the 5020 and put that $700 or-so real world difference in street price toward that inexpensive Panamorph lens releases last October/November. So your net/net is only another $500 or so out of pocket.

Wow. I really need to get a move on so I can pass another inspection smile.gif

I've been reading up on this more, which oddly enough is not making the decision any easier smile.gif However, I thought one difference between the 5020 and 6020 is the 5020 does not have native anamorphic processing. I may be wrong about that, so ill have to double check. Aside from that, the reviews put the 5020, 6020, and AE8000 all neck and neck with just a few minor differences. Now I don't remember why I had ruled out the AE8000 to begin with. Well, back to the calculator smile.gif
post #755 of 1535
The AE8000 is the new and improved version of the 4000. Its not quite as bright as the Epsons from what I remember and but they were tit for tat when I was exploring some time ago. One was better at this the other was better at that.

The power zoom and lens memory features of the Panny won me but I never planned to do a lens. Also keep the lens and carriage in mind when planning on the hush box and projector mounting. My box really is too tight for a lens and carriage.

Also AFAIK the 8000 still has to be within the projected image. I don't think the lens shift is powered. IOW when I zoom most of the 16:9 image spills off the screen. Thats no problem since its all black bars. For this to work outside the screen you'd have to power zoom, focus, AND lens shift to center the image. I dont think the 8000 does that. Worth a look to make sure since your still plottin..cool.gif...
post #756 of 1535
The projector doesn't have to do the vertical stretch - it can actually be done in any component. As of now, the Denon AVR-4310CI and AVR4810CI (and I think the Onkyo 818) receivers have built-in vertical stretch as does the Oppo BDP-103 and BDP-105. In fact some of these devices will also do 4K upscaling as well which isn't a feature found even in the 6020.

But you are correct, the 5020 does not have built-in vertical stretch.

I don't know if you saw this article or not: http://www.projectorcentral.com/epson_5020_vs_panasonic_ae8000.htm

Just remember, if you use lens memory on the 8000, you are only getting 810 lines of resolution and 30% less brightness. With the anamorphic lens either projector will have full resolution and brightness. However, the calibrated brightness of the projectors still gives the edge to Epson. And with the size of your screen you need all the light you can get.

EDIT: - The Epson also has RF-based 3D glasses vs. the Panasonic's which are IR. That's a big difference in reliable operation IMHO.

I may have hit another snag. I have a sneaking suspicion that some of my hat channel is 22 ga rather than 25 ga. The last piece I picked up, I said to myself, "self, this piece feels a little heavier. I must be getting tired." then I said to myself, "self, this one isn't as flexible as the rest, that's odd." Then I said to myself, "self, this one's harder to cut........... UH OH"

Unless someone has another suggestion, I'm planning to pick up a cheap micrometer from the big blue box store, and see if I can consistently measure a difference. This is really going to suck if I'm right. I was really hoping to get my channel up this weekend and order my DW on Monday, and take a day off towards the end of the week to start putting it up. If I have to order more channel, it will take another week to get here.

You could try weighing a few of them them to see if they are different weights.
post #761 of 1535
Well, that stinks.

If it makes you feel any better, my ceilings are all done with 20ga. Why? Because I didn't know any better at the time.

I think Home Depot carries the 25ga channel.. At least around here they do. Maybe you can pick it up and finish?

Oh no! I know that if I visit your theater you are subject to the RTROSE jinx, but I had no idea that it would or could extend to various builds through the forum. I guess if I'm in your thread you should have your firewall on and your anti virus up to date to make sure the jinx is filtered out and quarantined.

I too would suggest weighing them. I think that would be the easiest and fastest way to tell the difference. Sorry buddy, I hate stuff like this as it is very frustrating to say the least. However usually in these types of situations there are other things that we can do to at least stay productive build wise. You could take this down time to further research projectors!

post #763 of 1535
This time I won't tell you to just press on, but don't dally. wink.gif

If you are going to weigh them, make sure you weigh several at a time and take the average, so that you are measuring within the normal range of whatever scale you've got. (unless that means cutting a few inches and measuring that) Think back to your high school science days and measure carefully. OTOH if you go with the micrometer, maybe measure some on a shelf in the store somewhere (if there is a reference available) before you take the micrometer home.
post #764 of 1535
Are they not imprinted with the gauge and other information? Good luck getting things squared away.
post #765 of 1535
Aw well having something like that printed out on the channel would be a definite plus wouldn't it? You know it is the little things like that, that make life so much easier. If it is not, I wonder why not?

Good ideas, guys. Ill try to weigh a stack or two of them and see what I come up with. I was considering the mic so I could pick out individual pieces, but the difference in thickness is only a few thousandths.

And unfortunately, no. There does not appear to be any stamping on the channel. That would make way too much sense.

I should change the name of my theater to, "Theater of Mysteries" 'cause here's another one. (The short version, I have some 25 ga that's thinner, but I also have some much stiffer stuff that's marked the correct size for 25 ga, you can skip to the last paragraph if you don't want the details biggrin.gif).

Last night I started trying to figure out this business with my hat channel. I was planning to weigh a stack of them, but when I started sorting them I discovered I had another distinctly different type of channel at the bottom of each stack. Here's a picture of the two types



On the left, the stuff I found last night, is much lighter than the stuff on the right, and it's much easier to work with. The stuff on the right is the what I've been using so far, and requires two hands, some grunting, and a fair amount of sweat to get it into the clips. I shot Ted an email this morning, and from what he can see, he thinks the stuff on the right is 22 ga.

OK, sounds right, EXCEPT, I picked up one of those cheap digital calipers from Lowes, and measured several sticks. The stuff on the left is pretty consistently at 0.021-0.024", and 0.026-0.028". I'd guess about .005" difference on average. I also found a sticker and a hand written note on one stick of the thicker stuff claiming it's 0.018", which would be right for 25 ga. hat channel.

Oh well. I used the heavier stuff on the ceiling, and I HOPE I have enough of the lighter stuff for the walls. I'm planning to call the drywall company tomorrow and see what they can do. If they can actually find enough of the 25 ga, I may replace the stuff on the ceiling. If not, well, it actually makes me feel a little better with the heavier gauge stuff on the ceiling. I've seen a few references online that recommend 22 ga on the ceiling and 25 ga for the walls. I know there will be a loss in performance, but I wonder if it would be audible.
post #768 of 1535
So the question really should be is how did you get a mix of two different gauges? I can't remember how you got the channel, from a big box or online. I admittedly know very little about channel and clips et al, but why is the heavier gauge worse performance wise. No need to get scientific with an answer, just a one liner will do. wink.gif

heavier gauge = less flex.

I actually got my channel from a local drywall supply house. They were the ONLY place I've been able to find that could even get it. They had to special order it, and it looks like they found it stuck in the back of somebody's barn (mouse poop and all). They said they just don't use it anymore. The Home Depot's in my area don't even carry it anymore according the web page.
post #770 of 1535
Ah, got ya. Where in this case more flex = energy absorption which is a good thing in this case.

Strange though that different gauges would have been intermixed like that. One would not think of measuring and inspecting the channel to find out either, not something you would even considered (until now). I'm telling you I think the jinx can go through the web. Sounds like something that would have happened to me or Vik, not you.

You got it.

Ah, there will always be hiccups. Although, I never thought getting the hat channel would be an issue smile.gif

Sometimes in life I find that where we expect to find issues there aren't any, and where we expect none is where we find them. Building a theater is no different. The good thing is that its something that you can either work with or around with little problem.

Did you come to any conclusion about redoing the ceiling hat channel?

Oh the hat channel..... How I hate the hat channel smile.gif

Yeah, I'm planning to take it down and replace it. I ordered the replacement channel today, and it's supposed to be in on Thursday. I'm going to wait and make sure I get the right stuff before I take down what's up there now. I'd hate to get out there and find out they sent the wrong stuff again. On the bright side, they're going to take back the channel that I haven't cut up already.

Here's a fairly recent update. I've actually got the channel on the front wall and the other side wall now (using the correct stuff BTW).



Still a little bummed out that I'm not going to get to start on the drywall. I don't know why that feels like such a huge milestone.

It feels like it because it is a major milestone.  If it's any consolation, enjoy the calm before the dust. :)  I'd be frustrated as all get out if I had to redo that hat channel.

 

The room looks really awesome in that last picture you posted.  When you have the walls up, you should keep that picture around so, when people see your finished theater, you can say, "See?!  This is what I had to do to make this!"

I think I'm going to put a bunch of pictures and videos together into a montage to play during the grand opening gala so that my friends understand why it took my so long.

Tony, I think I got the idea from your thread now that you mention it. This is something I've wanted to do for so long that I'm trying to document each step of the way.

RT, well, now you've let the cat out of the bag. Now my wife is going to be suspicious about the drain being stopped up so often smile.gif
