    I'm back with new HT picts!

    It's been a hectic past few months as I have been focusing on starting up a new wireless company and working on my home theater. Well we began cellular operations on Oct 1st, the home theater is as complete as it's going to be at this point in time, and I have been watching a lot of movies. So it is time to get more involved here and share the fruits of my labor.

    The house I purchased in June is very unusual as it is built in 1949 and modeled on a Frank Loyd Wright design. It has almost no flat ceilings because of the "quonset" design, this curved ceiling design made mounting the projector very time consuming. Ever tried to measure placement using a flat surface and then tried to transfer those measurements to a curve? Lots of trial and error and holes in the ceiling.

    Well I moved my rack out of the front soundstage, made a shelf mount for the LT150/ISCO II combo and must say I have never enjoyed a home theater as much as this one. Images are smooth and 3 dimensional and with my Waveforms providing foundation for both HT and 2 channel, I'm pretty close to nirvana (or any other grunge band). I've posted some new picts at my HT site under my signature. Take a look and you guys tell me what you think. I'm open to any suggestions!

    I have one more improvement to the projector and that is to have it calibrated for 6500 color temp and proper gamma tracking, also going to have the black level improved through "Thumperization".

    That is one cool looking house!

    Nice HT set up as well. I don't understand the use of the anamorphic lens however. Are you pulling images of in a stretched mode, and then optically compressing?

      Thanks Bing!

      That's exactly what I'm doing. The lens allows me to use the entire 1024x768 panel. Compressing to a 16:9 display yields a smooth, screendoorless, and artifact free image. It also gives me 33% more brightness.

          John,

          Nice setup, but of course it calls to mind several questions, since I'm relatively new to the LT-150 bandwagon I'll ask away....

          1) Ceiling mount drastically increases the fan noise, what are you doing to abate the noise?

          It looks like I'm a bit closer to my PJ than you are, but in my system, ANY extraneous noise is noticable these days as the resolution increases.

          2) I'm not sure if it's the angle or what, but the screen doesn't look to be level when fully extended. Hopefully it's just the photograph.

          3) Have you made a pass at the projector with either VE or AVIA? The LIS shot seems just a bit "too blue".

          4) Am I missing your lighting controls? While the LT-150 does a nice job, it really shines (pardon the pun) in a light controlled environment. ANY extraneous light causes color washout. So much so that I've taken to covering the fronts of my components with black drapes.

          I have some screen shots of more mundane material in another thread here in the Video spot, or you can just check them out in my personal web space.

            Thanks John, nice photos and setup yourself. I'm really curious on how much a difference a Grayhawk makes as opposed to my Matte White screen.

            As to your questions.

            1) Fortunately the shelf abates the noise somewhat because it is far larger than the projector itself, partially blocking the fan noise. I would like to entertain the idea of enclosing it further as soon as I get time. Noise is an issue on very quiet passages and I have looked at the Whisperflow. The problem I have is because of the curved ceiling a ready made hushbox is going to be very difficult to retrofit. Also the back end of the PJ is only about 1" from the ceiling.

            2) It's the photo. I leveled the screen when I hung it and checked it again after I took the photo.

            3) I used AVIA about 7 times during my tweaking phase. The blue tint is from the inexpensive digital camera I used.

            4) I have absolutely no lighting control. The house has large expanses of windows and no window treatments. I can only watch at night, which is fine with me because of my schedule and I hate to cover up the view.

            One other note, I'm sitting 10.5' away from my 92" wide screen.

            Oh no! Lex knows where I live! By next spring we will have to have a HT/Keg/Barbeque!

              John,

              You should really talk to Dave Beatty sometime over the phone.

              He might have an idea or two....

              Hopefully my Whisperflow will get here in time for me to install it next weekend.

              Now, if I could just get my back to stop hurting ;-)

              Regards,

                Wow John!!..

                Great set-up.

                You definately have some serious gear in your HomeTheater.
                Good Job,,I will be over soon to watch some movies.

                    Trevor, it's such a short drive, come on over!

                    John, I would be interested in how much a difference the Whisperflow makes in noise level.

                    Andrew, thanks!

                      Wireless congratulations on your new company and I wish you the best. The HT looks wonderful. Your system certainly shows your hard work. That room looks like it would have some challenges but what a great view.

                        John,
                        Excellent new set of pictures.I can't get over the room. I would live there if I had that view. As for movie viewing in the daytime, who would want to.I basically do all my viewing at night,too, even though I have a dedicated room with total light control.
                        Regarding the Whisperflow. I have one for my Sony VPL400 lcd projector.The 400 is a very fan-noisy projector and the Whisperflow cut the sound substantially. I can still hear the fan, but it is not near as noisy as before the enclosure. I understand Dave Beatty has made some changes to the Whisperflow design, making it even quieter.I don't know how noisy the LT150 is compared to the 400, but I'd bet my projector is louder, so a Whisperflow could be an excellent addon for you HT.
                        Here's to good viewing,
                        George.
                        P.S. I'd love to pop over for an evening,too.

                          The whisperflow I have on order incorporates the latest noise abatement techniques, including internal noise dampening.

                          I wish I had an Audio Control SPL meter, as the fan output in ceiling mount mode is beyond the limits of measurement with the el cheapo Rat Shack meter.

                          I'm guesstimating it at 40-45dB but I have no clue how accurate this is. It could be as high as 50+. Oh wait, duh. I'll stick the meter right up to it and extrapolate. Sadly its right over my head in the listening room, due to the geometry of the room.

                          Ok, 62dB @ 2 feet. I sit about 6' away from the projector, that means approximately a 9dB attenuation, not counting the loss from the mdf board the PJ sits at this point in time. Call it 53 dB.

                          Not good. Very loud :-(

                          Regards,

                            John that is loud, I think mine is a little quieter with the shelf arrangement. Did you measure in proximity to the pj or up to the side where the fans are located?

                              This was to the side of the fan, approximately 2 ft away, which is the most convenient spot for me to measure.

                              But based on your room picture, you're a good bit further away than I am. This is key, as it'll fall off in an inverse square function.

                              Here's the key. Mute the output of your system, and see if you notice the sound of the fan. If you do, it's too loud!

                              Regards,
