Hello everybody!

I am a guy from diymobileaudio[dot]com - and i recently bought a house, a PJ, and i just built a 122" substrate from sintra.


i was ABOUT to mix silverfire 2.5 4.0 when i came across some crazy stuff mechman and the guys had posted, then i read for three more hours, and now i am thinking of selling the silverfire components!

so i have three real questions.


1. a neutral grey is all i need? n7-ish? i have a high ambient light living room that i will do my best to mitigate light (against my wifes wishes).

2. what paint do i buy?

3. do i need to prime the plastic before i paint it grey?


i have been reading a lot about blackwidow, and just off the shelf grey paints all over - but there has been so many dang suggestions. i have a graco hlvp gun - and i would rather use it than roll, i feel i will get a much more even paint by spraying - and since i have the gun i would like to use it anyway.

i am literally ready to paint - but i needed some clarification on the silverfire mix, and then i found out about the hot spotting and no scientific . so here i am.

please help me :huh:

everyone likes pictures. we just tore out the carpet, so i just set the speakers up to display how pretty they are - the pictures only had the towers hooked up in stereo. the substage will be two 18" incriminator audio flatlynes in the attic infinite baffle.

Are you going to darken up that window a bit with a blackout shade or are you going to mainly use this at night?

With that window as is I'd go with a an OTS N8. If you're going to darken it up some I'd go with C&S Ultra™ or an OTS N9. Calibrated, the Panasonic should give you around 650fL. Normally that would call for the C&S Ultra™ or a white screen. But with that window like it is, you may want a gray. What you can do is grab a N9 and a N8 sample at Lowes or HD and paint small samples and try them out before you decide. You can find OTS Grays here.

You were right to do the work and find the truth about avs. :T The diy screen forum at avs is Roland's (MississippiMan) personal sales floor. That's where he gets his customers from. He really has very little interest in anything other than making a buck and keeping people from finding out about the truth regarding his ridiculous mixes. There are so many things wrong with that place that it's best just to walk away.

Hopefully you can sell all that stuff you bought. If you have kids you can let the use it for art projects.

Are you going to move that ceiling fan?

Yes, fan will be moved. We just moved in two weeks ago and I don't even have the pj mounted.

Yes, i plan to darken that window, but the pj will be used mostly at night and the sun sets on the other side of the house, so after 5pm it's usually dark enough, but curtains + window tint most likely.

Why would a bright pj need a lighter screen? I would assume the brighter the pj, the darker the screen would increase the contrast and such? I guess ambient light is a number one fight, my wife likes to have lights on or she "falls asleep".

Thank you so much for your time sir. I can't explain how much your help means to me, i read hundreds of your posts last night haha. :dumbcrazy:

At 650fL and a 122" screen (unless I calculated wrong), you're just under 13fL with a white screen. It's a bright pj for a smaller screen - a 100" screen would have you at 21fL. I'd get samples and try them out to see what you'd prefer. With lights on you may prefer a darker gray screen for better blacks.

understood.

i don't really understand what unit of measure a FL is lol. trying to look it up online is an exercise in futility - i don't know what keywords to bundle with it to get results. i understand the lumen, but everybody speaks in acronyms and nothing is ever explained fully around here :p

i just don't want to make the mistake of painting this thing wrong. i mean i have like $150 invested in this sintra\wood for this frame\substrate - and i don't want to put the wrong coating on it.

my carpet is being installed in an hour - and i wont have time to paint it before that (and that was my goal) so now I'm stuck.


what i got from most of your posts - is a D65 (does that mean 65% reflectance across the spectrum of light?) neutral grey. and that GOLDEN Neutral Grays are balanced "steps" in value - and a good place to start looking is around N7~N9.


do i need to prime the sintra\komatex\celtec. i have not gotten a straight forward answer anywhere that says yes or no - and in my experience painting, priming is always a good thing.


thanks again dude. you are awesome.:spend:

hey req.

looks like you finally made the move over here (from that site).

if you want real and fact based DIY paint advice, you come to the right place.

good luck with your project, and post an update on the other site to let people know what you went with as your final paint solution so it would help others be informed.

There's a glossary of terms/definitions here. D65 is the illuminant value defining midday sun in western Europe. It is the neutral standard for video.

I wouldn't think Sintra would need to be primed. You could, but I don't think it's necessary.

Hi Mech!!:wave:

With 650 Lumens will get 15FL (14,9 to be exact) on a 122'' white screen. I agree with you on screen size. It is a pj for a smaller screen especially if our friend goes gray to handle better the light from the near window.

Is this the pj we are talking about?

If yes, i apologize for the confusion :hide:.

Your projector is very bright and you can use comfortably a gray mix even in 122'' in default mode and not calibrated!! Mech above was referring in calibrated status.

That's correct. I was thinking a 122" screen was 10 feet wide. :doh:

Nope. It's all good. :T You could go with a N8 if need be. And as I said earlier, I'd get samples made of a N8 and N9 and test those out to see which you prefer.
