Staple or grommet

Hello All,
Everything is almost done. Panasonic 8000ae mounted, Axiom speakers up, equipment rack built and got a great deal on the Pioneer SC 1523K. First theater so image looks great on the wall. I built the screen frame to accommodate a 140" 2.35 image. First row at 14 feet second at 19 feet.

Question: can save a little cash stapling to the frame vs grommets anyone have any experience with stapling or wish they used grommets instead.

Getting samples sent this week to decide between XD or UF.

Thank you

At 14 ft and 140 inches...I'd really recommend the XD. The extra gain will be appreciated.

I'm definitely leaning towards the XD and for the money will probably get it with the grommets. Since I really don't have any past home theater experience to draw from I think the extra gain of the XD will look better to me vs the possible better black levels realized by using the UF with the Panasonic 8000ae.

For me, I will will always choose a bright, punchy picture over a dull one with great black levels. I have an XD screen with a projector that has only fair black levels and it still looks great to me. Your Panasonic will be better in terms of black levels. On a screen that large you will definitely appreciate the XD. Get the grommets and save yourself a world of headache. My 0.02

I'm afraid the new UH or the Enlightor would hurt too much with the .8 gain.

So, that leaves me between the Falcon and XD, and from what I've read, the XD probably has a bit more gain and possibly a more neutral color.

The XD tests more color accurate. (Looking at two samples side by side I can't see the difference but I'm not very sensitive to color shift.)
The XD is less restrictive to high frequency sounds (measured).
The Falcon has slightly less visible weave close up, but at 12.5 feet viewing distance they would appear equally smooth.
I have actually compared the XD vs Falcon vs EN4K.

You can see the comparisons here:

Centerstage XD vs Falcon vs Screen Excellence EN4K

In summary:

- XD is a bit brighter than the Falcon (I'll guess about 10%). For most scenes, you might not be able to notice it, but on brighter scenes, you can clearly see the brightness (click on the link above to view the photos).

- XD's weave is not visible at 12 feet. In fact, it disappears at 9-10 feet but you might still 'feel' something's there. So, if you're sitting 12 feet from the screen, XD is the way to go.

With a curved screen you will have to overscan the image a little to hide the barrel distortion.

Sometimes the curve can be useful for countering reflections onto light coloured walls, but I've never meaured or seen any measures that say how good that is in comparison.

I actually bought the curved 16:9 screen. I haven't installed it yet.

However, a few days back i was at an AV show and there were several 16:9 screens that are a bit curved and they weren't using an anamorphic lens. It looks great. Gives you an IMAX feel.

I purchased the XD AT screen and got it setup the other night. I made my own frame from T slot aluminum, and purchased the screen with the grommets... It was a breeze to attach the material to the screen by my self. I am very pleased with the picture and I can not see any problems at all with the screen. I would recommend it to anyone who wants a excellent screen!

That is awesome! I'd love to hear how it comes out. Pictures would be great as well!

Measurements suggest Falcon is less acoustically transparent than the XD material.

I have referenced this report but have been hesitant to post the link. The measured specs (gain & sound attenuation) are invaluable, but I don't agree with some of the more subjective conclusions regarding weave and color shift visibility.
A direct comparison of samples in addition to a review of the test results will determine the best screen for a particular installation.

Agreed. Samples and real world tests are very important.

The measurements in the accucal report are great in that they are all done to the same standards, so you can easily compare relative performance in terms of gain, acoustic properties, and color shift.

The subjective summaries are... just that, subjective. They are the opinions of someone who has seen hundreds of theaters and measures and calibrates for a profession. So while not unassailable, and one should definitely get samples to see what's what and what matters to "you", they are a decent starting point.

Link is good. Must be something like a firewall or content filter on your end blocking it.

Link is working fine, but your ISP, employer, or filter software may not like a direct link to a PDF.

I can't access this site either. I am accessing it from my home computer so no firewall, etc... it's a server error:


-----------


403 - Forbidden Error
You are not allowed to access this address.
If the error persists, please contact the website webmaster.
If you are the webmaster of this site please log in to Cpanel and check the Error Logs. You will find the exact reason for this error there.

Common reasons for this error are:

Incorrect file/directory permissions: Below 644.
In order files to be read by the webserver, their permissions have to be equal or above 644. You can update file permissions with a FTP client or through cPanel's File Manager.

Restrictive Apache directives inside .htaccess file.
There are two Apache directives which can cause this error - 'Deny from' and 'Options -Indexes'.

It's definitely on your end, because I can hit the site fine. If you PM me your email, I will download it and email it to you. It doesn't look like you can attach an attachment to a PM.

Nevermind... i used a proxy and it works. Basically i think they banned some countries from accessing their website which is strange and a little bit crazy...

Looks like XD was rated best in class.

I am not sure how accurate the 'gain' is... according to the report, the XD is .94 and the falcon is 1.0 on axis. In my own viewing experience, it looks like the XD is brighter than the falcon by about 10% in bright scenes. Take a look at the pictures I posted in this link:

Centerstage XD vs Falcon vs Screen Excellence EN4K

Unfortunately, it's a necessary evil at times, as a means to try and stop hacking attempts on a server. If a site primarily has US visitors, for instance, they sometimes block IP blocks for much of Europe and Asia and other hotbeds of hack attempts.
