I don't think any of us need more cake.

Has anyone else here played portal, or am I the only one waiting on the companion cube?

Good idea.

Time to design the stage - all feedback welcome

Option #1 - 133.5" curve is a little wider than screen width (130")


Option #2 - 121.5" curve


Option #3 - lose a 1/2 foot of stage depth, curve is 133.5"

Option #4 - I think this is it - 129.5" curve 3' deep
post #218 of 587
How about a 130 inch wide curve, and lose only 3 of depth on the sides? so 33 deep on the sides.

OK - this is not scientific

130" screen with the 3ft deep stage and 129.5" curve (i think it makes sense to keep the stage as deep as possible)

this is a drawing of a 130" screen dead center on the wall above the stage (so centered on the 7.5ft above the 6" stage) - i think it will need to come down a little once we figure out seating and all that

I think it will work keeping the stage 3' deep - we should get an extra inch or two from the door joist, the door should open 90 degrees regardless

here's an almost sacrilegious question - i think i read somewhere that a 125" screen would make for more comfortable viewing from 12' away - of course i haven't run any of the online calculators - but should i consider going down to 125" from 130"??

Edit: it looks like the front of the riser will be 11'2" away from the front of the screen (straight horizontal) - This means the front row seating will be at around 10'

With seats - accurate dimensions





Feeling like the riser is too big at 7'

but then again there is a bulkhead that comes out a foot at the rear of the riser - pretty sure the ratios work out - will have to figure it all out soon
post #222 of 587
What seats are those? On the diagram they do look tiny. As a rule of thumb a reclined HT seat needs 6.5 ft of riser depth, then best practice is to position it well in front of the rear wall for surround sound purposes. If you have any depth to the rear wall columns and treatments you really need the 7.

I suspect it looks a little out of proportion because the walls aren't shown in your mockup. On top of that, if you have any columns or any treatments along the back wall it will help put things in perspective. And if you're still worried, just remember, BIG said this is how it needs to be

Great progress, keep it up!

Decided to go with a straight 4 seater up front to leave plenty of room for the aisles
post #229 of 587
Nice seats! Just be aware that when you have your buddies over that there will be a scramble to avoid being stuck with another dude in a back row love seat. There really isn't a need for aisles for the back row if you want all singles. we can make your equipment access high over the seat back.

I see a row of 4 singles is 122.5 inches wide and a row of 2 singles and a love seat is 116.5. Leaving aisles of 22.75 and 25.75, you can actually walk past a chair that is 18 inches from the wall. Need to plan for that column though at the front of the riser.
post #230 of 587
I've been thinking about the riser and whether Jesto should think about a two level riser with a 3 inch booster section under just the chair base. Assuming we need 12 inches of riser height that would mean making the traffic area of the riser 9 inches. Rough to scale diagram of the issue.

For a second, I thought those were the plans for Ironman.

Just got home and found this waiting for me in the garage:


100' roll of linacoustic


24 sheets of what should- mansville 814 (same as OC 703)

Turns out its from certaineed - looks to be the same but going to check on the acoustical properties now


Now... if only we can get the stage done this weekend - then I can line the walls with the linacoustic and build bass traps during the week

HMMMM - wondering if this CertainTeed vs Manville insulation is a big deal

The NRC looks like its .95 vs 1.05 for the Manville and 1.00 for the OC703

CERTAINTEED 300 2"
OEM 300 2" (50mm) 3.0 pcf 0.17 0.76 1.05 1.02 0.95 0.96 0.95

MANVILLE 814 2"
814 2" (51mm) 3pcf (48kg/m3) 0.24 1.00 1.11 1.08 1.06 1.05 1.05

OC703 2"
703, plain 2" (51mm) 3.0 pcf (48 kg/m3) 0.17 0.86 1.14 1.07 1.02 0.98 1.00


What do you guys think - is this enough of a difference to not use it for my corner bass traps??

I hate to raise a stink - but this kind of pisses me off- you buy one thing and they deliver another - just on principle i'm really annoyed
*they did throw in delivery for free next day - but still

the 814 has the best NRC so i'm tempted to call them and have them come replace it or just refund me the money

what would you do?
post #234 of 587
If it really bothers you, it doesn't hurt to ask. I'm definitely not an expert, so I can't tell you how much of a difference there is. At a minimum, I would want to make them aware that they didn't send what you ordered.

I agree. I would do the same.
post #236 of 587
Its probably perfectly fine - but if you specifically ordered something else, they should at least give you some type of a discount.
post #237 of 587
I would think only the first number is important that is the NRC for the lowest frequency measured, 125Hz. OC and this product are both .17 at 2 inches.

OK - so looks like consensus is it probably wont make a huge difference (even though it seems to underperform the others) - it's just a frustration

kind of feeling like its not a big deal- but just a little irritated that i ordered one thing and another was delivered without any heads up

I've already let them know via email and will call on Monday - need to order more panels for the DIY acoustic panels at some point - was hoping to use the same source - we'll see how they react on Monday
post #239 of 587
Yeah hopefully they can comp/discount you on some of the stuff you'll need later
post #240 of 587
nothing really to add other than this is one of the builds I really look fwd to updates on ... and with the pace you're going, it's daily!
