I'm upgrading from the JVC SX-21 to the RS-1 (coming this week), and I had two questions:

1) My SX-21 had a brightness specification of 1500 ANSI, while the RS-1 is rated at 800 ANSI. Does this mean my RS-1 will be roughly half as bright as my SX-21? (Edit: I should add I have a dedicated, light-controlled HT, no windows, dark eggplant walls, 50% gray ceiling.)

EDIT again: Found the foot specs in the online manual. Question 2 deleted.

Thanks. :)

it wont be half as bright because your SX-21 was never 1500 ANSI. They may have quoted it but thats not what you were actually getting. The RS1 is close to its spec. The SX-21 may be brighter, but not by much

You can download the manual here. It has all the size specs with drawings.

Thanks, Santellavision. I just now found those foot dimensions and edited my questions accordingly. Appreciate the help. :)

- TomI can't answer your question exactly, remember the RS1 is 700 lumens calibrated. I project onto a 92" diag. white matte unity gain screen and I use an ND2 filter to cut down the light and the image is still bright.

Also the SX-21 is a 4:3 projector, and the ANSI is rated for the full panel. When you use only a 16:9 part of it the lumen output would be lower (75% of the full panel), and that's the value you should compare with the RS1, because RS1 it's a 16:9 projector.

So, you should be comparing 1125 to 800. In reality it's also not the correct comparison to made, because the 1125 from the SX-21 is not calibrated and the RS1 is.
