Assuming that a person doesn't need access to the wall behind the screen, why would someone buy a Model B screen instead of a Perm Wall screen? The answer might be as simple as, "they wouldn't." But I'm a stupid newbie... so I thought I would ask.

If you get a Perm Wall, then you don't have to deal with "drop" and factoring "drop" into placement calculations. What am I missing? Thanks.

The Model B is about half the price of a Perm Wall.

Does the Perm Wall have any advantages over the Model B? The the Model B have "tensioning" problems that the Perm Wall does not? Thanks!

Tim is correct in that the Model B is about the least expensive screen available. The advantage of a fixed screen is that you will not have any movement or waves in the screen. Pull-down screens are susceptable to waves in the surface unless they are tensioned. This can hinder the effective picture when watching a movie.

Thanks!

Jason,

Does this strategy seem to make sense? I plan on buying a 106" Diagonal Model B High Power for television use and my intro to movie use. Then, in a few months, I'll buy a PermWall 16:9 screen, of the same width (92") as the 4:3 screen, and mount it behind the Model B. That way, I can use the High Power for TV use and "upgrade" to a better screen later. Thanks!

Seems reasonable. As long as you don't mind the added cost of buying 2 screens.

Thanks!

Thanks Jason. I've seen many people who posted great results with the Model B with no complaints of waves. Is the Model B prone to the waves you suggested? Does the Model B come in "tensioned" and "non-tensioned" flavors? Thanks again!

Jason Turk 08-13-2001 06:53 PM

The Model B has a "tensioned version" but it is not tab tensioning. It is an arm that you pull down to put pressure on the bottom bar of the screen. It doesn't work all that great and you need special brackets to wall mount it.

Thanks!

Don,

To continue with what Jason was talking about, the Deluxe Model B (Tensioned version) needs to be mounted either from the ceiling or off extension brackets. This is because of the tension arm that is attached to the back of the case. We sell 6" extension brackets that can be used with that type of screen. As for the tensioning arm itself, yes I will agree that it is still more prone to air movement than say a fixed screen but it still eliminates movement too some degree.

Just wanted to add my 2 cents worth.

The screens will be at slightly different throw distances, so you'll have to re-focus each time you change between screens. Since you intend to use one for TV and the other for movies, you might be able to survive optimizing the focus/throw for the movie one and live with a slightly out of focus TV.

Thanks guys. I'm looking at the Model B now .. but am worried about its lack of tensioning....
