For my situation, however, I need to make sure it'll would work well (i.e. be bright enough etc) for a room where the projector will be ~23ft from the screen and the screen is 8ft x 11ft. Would the JVCs recommended here work well for that, or should I be looking in a different direction?
You need to tell us more about your room and the type of screen to be used. Also do you want to use it for 3D or just 2D viewing? It the screen has moderate to high gain then then the JVC projectors should put out enough lumens for 2D viewing if your room has full light control.
You have a 3 x 4 aspect ratio screen, so you will have black bars at the top and bottom for all virtually all HD program material. For your screen width of 11 ft. then when projecting normal HD aspect ratio of 1.78:1 (i.e., 16 x 9) video, you will have an effective screen size of just over 150 inches diagonal (roughly an image 11 ft. wide by 6 ft. high). With a 23 ft. projector to screen throw distance this means with a JVC projector you would be using the zoom set near mid zoom which would result in a little more light loss than is possible with a shorter throw distance. If you were to use a moderate gain screen, with a true gain of 1.3 then you would get perhaps 14 to 15 ft. lamberts of brightness off of the screen when using a JVC projector with a new lamp which would be considered adequate by many people for use in a totally light controlled home theater (12 is consider the minimum and 16 ft, lamberts the ideal by some industry standards). However as the bulb ages its light output will drop and therefore it would be better to use a screen with a gain of at least 1.5 to allow for some lamp dimming over time. Also note that the gain values published by the screen manufacturers are often higher than the real gain of the screen. If you could mount the projector close to eye level, rather than near the ceiling, then a high gain retro-reflective screen such as a Dalite screen using their "high power" fabric, with a gain of 2.4, might be your best bet.
However, it sounds like you already have an old 3 x 4 screen in place and unless it is a relatively high gain screen then you probably would be better off using a projector with higher light output than the JVCs. At well under $5K (actually about 1/2 that amount) you could get an Epson Home Cinema 5030UB or for additional dollars the similar Epson Pro Cinema 6030UB. While when calibrated for the best possible picture these have similar, or even a little less, lumens output than the JVCs, they do have some much brighter modes than can be calibrated to provide a reasonably accurate image. Another alternative for a higher lumens projector would be the Sony HW55ES (under $4K). These Epson and Sony projectors have manual focus, zoom and lens shift controls instead of the JVC's power controls and lens memory.
