Fabric track is all done and so is painting......

Crown and rope light is next on agenda.

Messing around with tablet........with all complaints about my photography skills.............well, I'm trying to improve. :

Looking good, Cory!

Regarding all the questions in your previous posts. Even without Atmos, the price of the 8801 will go down once a new model is introduced and it has aged another 12-16 months. The unanswered question is how much will the lack of Atmos functionality contribute to the lesser price. I don't think anybody could answer that. Even if the differential is $500 less, it's worth it to keep your room's reference quality sound and calibration....things the Denon can't do or doesn't do as well.

I think the rarest of outputs on any upcoming high-end preamp output would be the third pair of ceiling speakers, but that's just my opinion. I wouldn't sweat any unbalanced RCA preamp outputs. Yes, XLR is preferred, but the reality is that you're never going to hear the difference. In fact, if you actually hear a difference I'll give you a dollar.

Regarding your heights channel proposal. The reason I only briefly considered and then almost immediately rejected heights and widths channels is that they are not 'real'...they are matrixed channels and not discrete. Moreover, opinion of the differences between professional and amateur alike was luke warm at best. Of course you'll have fanatics at both ends of the spectrum, but in the end, opinion was a solid 'Meh'. I wouldn't mess around with it IMHO. I know what you are going to say - in most media the side channels are matrixed and not discrete. That's true, but there are many movies that are encoded in discrete 7.1. There were only 3 sucky movies ever produced in DTS Neo-X, which is dying (has died) on the vine. The matrixed side channels also bridge a 15-20 foot gap between speakers as well, so their presence makes more sense.

Your thoughts?

Gotcha.........

Understandably, heights are not discrete but are matrixed with rest of mix.

I have no problem waiting on purchasing speakers until a suitable processor candidate is available. For the time being, I had a thought maybe buy two height speakers now and use since 8801 can utilize heights. When suitable processor is available, then just purchase an additional pair of ceiling speakers for rear.

Just thinking out loud..........buy two Silvers now and use until Atmos processor is available then buy two more Silvers for rear..........or I can purchase all four speakers later at same time as processor.

Just seems silly to me buying all four speakers now and wait........

Clear as mud?

Final verdict which will dictate possible speaker outcomes..........how much depth do I really have? See for yourself:







8-1/4 inches.......I inked out as much as I could. Opens up more possibilities. Makes sense adding four more Triad Silver LCR's in angled baffle..........we shall see.

On processor front.......what is a year old Marantz 8801 worth? Seems to me, $1800-$2200 is going rate. Far cry from MSRP of $3600. Worse than buying a new car concerning depreciation. I'm going to look into Marantz 8802 or Roger Dressler suggested looking into Marantz 7702. Must do my due diligence!

The amount of energy and work you have been putting into your room is amazing. I have really enjoyed reading all your post and the all help you have received is awesome.

Almost finished your amazing thread and saw this. This is the advice I am going to follow before I implement Atmos. I want to do the 9.2.4 in my room.

It might be wise for me to copy TMcG's version of strategic "Loganization." In other words, wait to actually implement Atmos when second generation processors are out so I can implement an Atmos system of 9.4.6.

Thanks for the kind words and complements.........

Having a build thread sure helps since there are so many intelligent, helpful people who are willing to give their experience, knowledge and advice freely. When unsure of direction, I know I can count on receiving sound advice from fellow members.

The only sad part about this journey, everyone lives so far away from my location, they don't have a chance to experience fruits of my labor.

Glad my thread has been helpful........we're all on this train pioneering path to implement Atmos........I'm feeling confident this project will work perfectly.

Mapping out possible location for diffusion in rear bay. Most likely will Velcro until rear speaker size is known along with location.

Will give Acoustic Frontiers a call today and order four of these.......






Also trying to source locally OC 703 and am waiting on a phone call.

Placed order for four of these:

http://store.acousticfrontiers.com/A...fuser-DC2.html

From Acoustic Frontiers........7-10 days before shipment since AF only having one in stock. Diffusors will be black.

Spent this morning mapping out diffusors so I'd know how many I needed. Locations will be temporary until rear Atmos Speakers are installed.

I like acoustic treatments! Especially when someone else is paying I'm probably an oddity, but I sorta like the way they look, too.

The ceiling looks great! You should be proud, sir!

Had a great surprise! My cove was delivered a day or two early!

Last couple hours sanded, pre-stained, and just got done staining. Later this evening, I will be using three rattle cans of satin lacquer and should be done with staining/finishing wood. Later in afternoon tomorrow, I'll be pin nailing and gluing cove adjacent to overhanging fabric track.

I'm still waiting on 12 OC 2" 703 panels, fabric samples for cloud, and probably two weeks for diffusors. Getting there........




Cove was delivered at 10 AM today and have been working on it since.




Cove has been sanded, pre-stained, and now stained. Will finish later today.





Crown molding has been waiting two weeks for this day............need to breakout tack cloth and clean........lots of sawdust as you can imagine.

Cove is done.....all fabric track is 1/16th above cove.

Cove sure adds detail to perimeter beams besides allowing for 8-1/4 depth for speakers and acoustic treatments.









To do list:

1) Going to Builders lighting and picking up rope light and hardware
2) Crown
3) Electrician for lighting, comm wire from GE to rack, dual receptacle for rope lights
4) Fabric.....sample is coming for Black Sensa
5) Acoustic treatments ie absorbtion and diffusion.

Final measurements for height in room are now official.

I was so worried about losing too much height building coffer cloud yet in the end decided to give up some height due to Atmos implementation.

So Atmos cost me 8-1/4 inches in height:

Measurements now for height in room are from floor to base of cove in front of 1st row, 9 ft 6 inches.

On riser by second row, riser to bottom of cove 8 ft 4 inches. Plenty of head room.........still seems tight to me as our home has 10+ft ceiling height throughout.

Room seems a bit smaller........but ceiling in front between cloud and screen is still same at 10 ft 3 inches. Perimeter of cloud ceiling maintains same height which still gives room sense of volume...........definitely more cozy.

Looks amazing! I'm certainly envious of that ceiling height. I remember when 9' ceilings seemed like more height than I could ever need. Bahaha! I was so naive.

What's the ETA on when you expect to have it all buttoned up? Don't worry, it's just you and me here. No one will try to hold you to the date

I remember the post saying it would be a week or so before the acoustic treatments came in. I must have missed the deadline.

It would be interesting to start a sticky thread where everyone has their deadline posted for all to see followed by when they actually finished That, I think, would be quite enlightening for the group!

never commit to a date unless your compensation depends on it

Make your worst estimate and then multiply by pi. Then you'll have a decent shot at making the deadline. And - if you change the scope, don't forget to recalculate.

Thanks,

Yup, said two week a few days ago.......diffusers will ruin that timeline!

Fabric samples should show up tomorrow or Friday. Will take less than five minutes once I receive samples. If none of the blacks work, I'm ready to use Meander Boulder.

The high ceiling height is becoming very advantageous! Distances to MLP are farther therefore helping with locating speakers in cloud with out hotspotting.

Thanks again for complements.......

Time to get to filling holes......seams, miters, etc.........this part I really hate!

Look what FedEx man brought!


Called Fabricmate on Monday......have samples late Wednesday.........

Trying to decide between Sensa, 701, Anchorage and Meander Boulder which is not being tested.

Put all three black samples through rigorous scientific testing.






First impression, Sensa looks like Anchorage ie. same weave or should I say lack there of. Obviously, Anchorage is a lot thicker and not as see through, but texture looks very similar to Sensa.





Comparing 701, my wives first impression was burlap........she didn't like it at all. She definitely preferred Sensa.



Sensa and 701 pretty much block the same amount of light which makes sense since both have same acoustical properties, but Sensa is definitely better looking material.




Most definitely Anchorage was thicker material and had least amount of light bleed.........hence not near as acoustically transparent as other two materials.

I think I'll order five yards of Sensa tomorrow.
