looking to purchase 4-6 short throw projectors for corporate a/v on 6x9 screens....I currently own an nec 3000 lumen ultra short throw....great as far as distance and coverage but not as bright as I like it...suggestions please?

do you mean 16:9 screens?
we are getting good results with the Panasonic PT-EX/EW/WZ range, with the ELT-W21 0.8:1 lens. 5,000/6,000 lumens, good i/o panel, no SDI though.

Your consultant, contractor or the dealer from whom you plan to purchase the projectors should be able to help you select an appropriate solution, however they may ask if you can provide any more details such as what image size(s) you need from what distance(s), whether you want a particular resolution, what signal inputs you need to support, the budget and so on?  Are you okay with ultra-short throw projectors that have to be at a very specific location relative to the screen based on the image size or are you looking for something with some flexibility in the projector location?

The screens are 6x9 da lite fast folds....I would need both VGA and HDMI inputs...distance should be no more than 5 feet...

6'x9' is a 1.5:1 ratio, so that is not a standard video format, which makes it a bit difficult to know what resolution and format you are looking to support.
 
Assuming 4:3 format and the 6' height, thus a 6' high by 8' wide image, here are some options.  Assuming 16:9 or 16:10 format and the 9' width, thus a 5.06' to 5.63' high by 9' wide image, here is an option.  All but the latter option are not going to be much, if at all, brighter than your current projector.

The 6x9 Screen is not a definite...What would be your suggestion to something similar in size...I like the widescreen screens

...so why do you want an 8'x6' or similar size image?   Would plasma displays not be a better way to go?

The room is too big for plasmas...I like to get some high powered dual lamp projectors with short throw lenses...any suggestions?

You're missing the point.   You have indicated people will be VIEWING the image at no more than 5ft, hence my suggestion that plasmas may be more suitable, which, incidentally come in many different sizes.

5 ft is the distance I want from projector to screen...the people will be further away

I think you're missing the point. There was never any mention of audience distance, only projector distance.

6'x9' would be an old 35mm slide format screen, which were 1:1.5 ratio. No video format is going to fit the full screen.

The widest lens I have seen work fairly well was a 0.8 lens which would give you a throw of about 7'3" for 9' wide. Even that lens had fall off at the edges, and was soft at the edges as well if it was in focus at the center,

I agree with all of the above, every short throw lens I have seen has been very soft in the edges and usually has a fair bit of barrel distortion too.

There is a new Panasonic lens out now however that actually performs rather well. http://panasonic.net/avc/projector/products/dle030/

This is the DLE030 - a 0.3:1 lens that works with the projector facing away from the screen right up close to it. When I saw it in the flesh the image quality was good and there was no need for keystone or other geometry correction to get a good image from it.

Light output appeared to be quite even across the screen too.

There is, of course, a trade-off. If I remember rightly, there is a 30% loss of light output through the lens. That means much brighter projectors for a given application, and the lens itself isn't the cheapest.

I only mentioned this as the OP is looking for a dual lamp high brightness projector, and the Panasonic range is well featured in this area. I would say on a 9ft wide screen you would be looking at either their 8 or 10K projectors with this lens!

If you add the requirement for dual lamps I don't think there are any projectors that meet all of your requirements.  You might need to deal with with either a smaller image or a larger throw distance in order to get dual lamps and a noticeable improvement over 3000 lumens.
