That stuff is like $379 a gallon!

How much surface area does it cover per 150 ml bottle? Website doesn't say.

whoa... we have to get some of this..!

They make a jab on their site. He is the artist that got the exclusive rights to use Vanta black on some high profile art project. Meanwhile we would be buying that stuff by the gallons if they would just sell it!!

Not available to Anish Kapoor


thanks for the heads up!

I figure this stuff is perfect for the recessed light fixture trim just above the projection screen.

My only fear is that it's TOO BLACK and now I have four circular black holes above my screen that make my other velvet treatments pale (bright?) in comparison

edit: well I ordered 300 ml of this stuff. I'll report back --

I just ordered 6 bottles of it, great heads up thank you!

Hopefully it's enough to paint at least 1 of my 2 18" subs that I painted with the rosco. they look positively grey in comparison to the rest of the room so I drape the Royalty 3 over it and they disappear during movie watching.

it would be great if this stuff was that much darker than the Rosco and close enough to the velvet.

Let's trade notes when they arrive so we can let others know if this is a good purchase. Anything for the pursuit of pure black!!!

That's exciting. Looking forward to hearing about your views on the paint. Hopefully, you'll share some pics to show off the results.

Nice sub! One question? How the heck did you get the velvet fabric a perfect straight cut??? No matter how careful I cut my velvet it never got a perfect straight line and looks a little wavy in comparison to yours.

I don't think paint is ever going to do as well as treatment with velvet etc but I have no complaints now that I added velvet panels to absorb the letterbox overspray at the bottom when zooming.



Our room is also for general use when the blinds go up so black would have been too oppressive IMO.


Exactly the same for me.

I used Dulux drive time as my paint

Thanks, I built 2 and building 2 more. They rock my house off the foundation, love them..

The velvet is just folded in half and it makes a nice seam and then drape them over the top.

When this paint arrives, I'll show it vs the Rosco and Royalty 3 for reference.

You can also use a rotary cutter and cutting board using a straight ruler edge (I used a 4 foot T-Square) to make straight cuts. That is what I used and it worked great. I made the cut from the non velvet side.

The fellow we bought the paint from sent a link showing some details of the paint. It's good that it's pre-mixed and can be diluted if needed. he mentions it looks like velvet/flocking which would be great if it's even close to being as dark as the real deal.


it has to be darker than the Rosco and that would be the main goal

I decided to do some reflectance measurements on some black materials I had on hand. I can get in to technical details if anyone is interested but to put it in a broad stroke, the percentage reflectance data represents the total reflectance at all angles under reasonable viewing conditions. The chart is the spectral data that I pulled from the instrument used. Please be aware the upward slopes in the longer wavelengths aren't that significant when weighted for our photopic vision.

The samples compared are: Black DMD fabric sold by Acoustimac, Black flocked adhesive paper from Edmund's Optics, Protostar Flockboard, Black Ribbed Trafficmaster carpet tiles from Home Depot, and Fidelio black velvet used on screen frames.

So here is a summary table of photopically weighted reflectance with a D65 light source:


Here is the spectral chart:
I know the post above is not terribly recent but I was wondering if anyone has yet done a controlled comparison of Fidelio vs. Hobby Lobby's Black Solid Triple Velvet? And if so, to the extent that one is quantitatively superior in reflectivity reduction is the consensus here that the difference is sufficiently significant to warrant an investment in the "superior" fabric if cost is removed from the equation?

Further, does anyone know per the Cloudy Nights Flocking Materials Test if what is listed as "Deluxe Black Velvet (older Royal)(Jo Annes Fabrics)" is comparable to HB's Solid Triple Velvet?

I am in the midst of undertaking a partial redo of my bat cave and intend on covering the already existing black matte painted ceiling/black-dark maroon fabric walls with one of the velvet products. I bought a bolt of the HB velvet today and visually compared it to JoAnne Fabric's Royalty 3 (the only difference apparent to me was that the R3 had more of a sheen to it). Until I stumbled across this Thread I was completely ignorant about the impact stray reflections have on CR. But after conducting some tests using both soft light and a green laser, I was shocked to see just how much stray light my room produces and so I am determined to fix that situation.

I spent a lot of time comparing the (Jo Ann) Royalty 3 fabric to Fidelio as I was looking for something to wrap my speakers.

With lights on and up close, the darker difference is apparent with the Fidelio. However, from my seating position (about 9 feet from speakers) I could see no difference at all with the lights off and watching a variety of content.

Really interesting video. Though I am hesitant in painting my Tannoy LCR speakers that sit near the screen....I may buy some and paint a thin glass top to sit on top of the speaker....it would lay perfectly flat and you wouldn't have to attach it to the speaker finish to stay in place. I could never get protostar material to lay flat.

Since this product would cover anything with the same effect....you can pick the material to paint that has the best characteristics...stay in place and lay flat (without attaching it to the speaker).

David, how much of the Fidelio material did you have to use before you were convinced to go one way or another?

It would be great to see a direct comparison between Vantablack and Black 2.0. I hope the latter can compete when shining a laser on its surface. I love how it looks when not watching a movie, but if I had it to do over again I wouldnt put recessed lights above the screen again. Pointless.

It's funny you said that about the Recessed lights,I disconnected mine that are 2' from the screen,after I did my Ceiling in velvet,and even with the Rings painted Flat Black with the High Temp Bbq paint you could still see some reflection. They are now covered under the velvet,but still assecible if I ever want to change the room.

I had a piece that covered the top of my speaker. At times, I also split the top of the speaker with half Fidelio and half Royalty 3.

I've been using Flat Black Curtains on both the left and right side of my room. The effect was good,and I liked the look of the curtains instead of just a wall. Fast forward this past week,I bought enough Syfabrics Triple Black to use as curtains,I just Stapled the velvet to the curtains so that the staples were not visible,I was hoping not to see any metal shinning,the difference is night and day! My room was good before but now it's great! With the lights on the room still has that old theater look with the velvet curtains which is what I wanted,while watching a movie all you see is the image. With no movies playing you cannot see your hand in front of your face. I have a RS400 and I was thinking about upgrading to the 520 but with the velvet added to my curtains I have no desire at all. Movies look that much better,might have to call ChadB for a touchup now!

Anyone have any suggestions for some minimal lighting for my batcave? Walls and ceiling and much of the floor are velvet, so even with the one ceiling light on -- a recessed baffle trim, with a 45w spot bulb, in about the center of the room -- people are always tripping over things, banging into the surround speakers, or stumbling trying to get to the seats on the riser in back. I would like some light in the back row until the movie starts, and sometimes I would also like some light there for my wife to sit and hang out and read or surf while I'm playing a videogame. But of course I don't want to wash the screen out anymore than necessary.

I swapped out the recessed baffled for a recessed eyeball and aimed it at the back seats, but somehow it seems like the screen is even more lit up than with the baffle light pointed straight down.

Ideally I'd like to replace the center light with the perfect trim/bulb combo to get light on the seating without washing out the screen, but if necessary I will put a different light over the rear seats. Is a baffle really the best option for keeping the light from spilling to the screen? I was kind of shocked the eyeball didn't beat it hands-down (much less at all). Should I go with smaller trim/housings (this is 6")? Would a par20 spot be noticeably better than a par30?

Drapes lux measurment

I recently upgraded to a StudioTek 100 screen (thanks Mike!). Thought I would post some about the room treatment changes I did and a simple lux measurement.

I already had dark gray carpet/ceiling and blackout material on front screen wall for a combined border of about 2 feet all around the screen. Side walls are midnight blue (dark) with a little lighter blue acoustic panels. For the ST100 I completed the blackout of the front screen wall around the screen. I added black velvet material (protostar) for the speakers (non AT screen) and installed black velvet curtains on the side walls that I can pull out from the front screen wall if I choose.

The velvet drapes are a bit of a mixed bag. I don't think the velvet is as dark as it could be and they are heavier than I would like. The velvet seems close to the Joann blizard fleece with a hint of blue (warmer). I just impulse bought them and should have done more research. Half price drapes Warm Velvet. They also have a white backing that is not visible but adds weight and further reduces the acoustic transparency I suspect. They are not bad but I wonder if I could find better.

I put up a full white image and measured from my center speaker facing the projector. This area is outside the beam of the projector. With the velvet curtains not deployed I was getting 1.9 lux. This should mostly be reflections back toward the screen but I suspect some directly from the screen even though I had the probe facing away from it and below the beam. When I pull the velvet curtains out so they cover the first six feed of the side walls I was getting 1.6 lux. That's like a 15% improvement. There is plenty to dismiss on the methodology but I found the reading of interest that the drapes did drop the lux measurably. This was at the center and I may do some on the sides to see if it is more pronounced.

I may look for less weight and possibly an acoustically transparent "velvet" curtain if there is such a thing. I see some have made curtains out of Joann Royalty 3 Velvet. Ideally I would like to find a place that makes custom drapes and pick a better fabric. Anyone have any suggestions?

I have enough protostar to do the first four feet out from the screen on the ceiling. Some concern if it will stick as I found it somewhat less tacky than I would prefer in using it on some of the front screen wall. My other option might be to paint the ceiling with that Rosco stuff. This thread is a blessing and a curse. It is an OCD nightmare with always something more that can be done.

Sounds like we have a similar set-up and room. I too have the ST100 screen (love it) and am using Protostar on the side walls and Rosco for the rest of the entire room with black carpet. I have Royalty 3 velvet around my front speakers and subs. Not sure if you can see it (even with cell phone camera flash, it's hard to see), but on the very far left I made a window panel out of Styrofoam to cover the window - wrapped it in Duvetyne material.

Very nice! That is another step beyond what I have done. I think painting my ceiling (or other treatment) would be my next biggest improvement. Did you experience your room before you painted it with Rosco? Curious for first hand feedback on its impact.

I also made some masking panels out of gator board foam and covered them with protostar. I can use them to mask down to true 4:3 material or anything less that 16:9 like a few of my Kubrick movies. In addition if I want more lumens for 3D I can use the lens memory of my projector to make the screen smaller and then mask them left/right (I also have electric masking for the top/bottom built into the frame). That protostar is some cool stuff and the panels are very light weight. I treat them carefully as they would not hold up to any hard impacts but when installed look solid like they belong.

Hi All,

Have an opinion question - I want to black out part of my drop ceiling. But I want to do it the laziest way possible. What is the best approach? Could I take syfabrics velvet, and roll contact cement on it and just roll/paste it on over the grid/tiles?

It is pricey but protostar makes panels intended to fit under ceiling tiles. I have not used them. I have used the flexible stuff and it is great. You could check out their web site with a search. They also sell tape to cover the grid. FYI. Flockboard sheets I think is the name.
