cavi, red, thanks for the complements!

I need to take a pic with all the speaks in there...... Maybe tonight I'll get up there and take some shots, it's just frustrating to look at it all so close and yet so far.

I think I can!!!!........

Hehe, as promised heres some pics as promised. Until I get back from vacation a week from Friday, there will be no progress. I hope to order the screen soon after that and start saving for seating.......







Of course those bright kevlar cones will be covered up after initial setup, but they help you see where the speaks go anyways....... Also I know the DSX wides are a little narrow/close, but they would not fit into the picture otherwise and until seating is in place the speaker placement is "negotiable."

Also note the two MFW-15s in between the centers and the mains, which I hope to replace with 4-8 sealed DIY MFWs in the future....... Anyone interested in Moho diamone MFW cabinets for turbo upgrades?

I would also experiment with our main placement. Try placing them behind the screen and that would improve your spacing on the wides. If you like them behind the screen, then I would cut out the AT fabric of the wall so that the mains do not have to pass through the AT fabric of the wall and the AT fabric of the screen.

Have you given an thought for a masking system for 1.78 material? Should be pretty easy to do. By the way, you will have a nice room when you are done. Shaping up nicely.

Thanks!

have been on vac for last 7 days so haven't been able to use Internet or phone..... Sitting in MIA right now trying to get home

Those are some good points..... Remember, I only brought the wides closer in for the picture, they can be moved out to accommodate the recommended angle but they wouldn't fit in picture.......

I toyed with putting them all behind the screen, and still may, but it was awful close to the screen boundary and would certainly be behind the masking. As of right now I don't intend to make the masking AT. Even if I did i would have to EQ separate for different aspects since the tweeters would now be firing through the masking. I'll prob use the rest of the black felt I have left over and mount to foam board. Maybe hold in place with Velcro? Masking plans are not final yet......

Thanks Diaz! Oh BTW I corrected my post in your sub thread. It initially said "I would change the look......" and should have said "It* would change the look....". Darn iPhone is hard to type on......

The room has been a bit stagnant due to vacation getting in the way, but lots of stuff on the way!

shot a quick vid to help get a feel for the room, plus I'm restless till the stuff gets here.....

Affixed screen material last night, and put border on. Man this was hard to do. Getting it tight without having any wrinkles or letting the fabric bunch up.

I still have a couple small wrinkles to pull out, shouldn't be too hard to do. I couldn't post pics or vid with the wrinkles in there its just too impressive to have an eyesore like that on display.

Also, I will say the screen looks HUGE in the room after adding the material. I did not realize it until the frame was all filled up.

pulled the border back off two sides and re-tensioned to pull out those two wrinkles.

it looks good.

Question: it's taught but it will wave if you push on it. Anyone have problems with the screen waving from the subs behind the screen?

Thanks jahweh!

Well the palliser chairs came in yesterday. I unboxed two of the chairs before the driver could get away. Major damage to both of the chairs I opened on the front. Gashed leather and some wood even coming back. I refused the whole shipment, well see what happens next.

On the bright side the screen is done and came out wonderful I think. It really looks bigger with the material on it.

Little teaser update..... Chairs and projector installed. Overall really impressive I've spent about a week with it now and it still needs a lot of tweaking, but it is pretty impressive.


QUESTION: I have an in wall A/V rack which is stuck through the wall into the attic in the back. The rack keeps cool enough but the heat from the rack and the projector really heats the room up too hot.


My options are:
  • Do a crossflow cooling setup pulling cool air from room and vent the rack to the attic.
  • plumb ductwork from downstairs to bottom of the rack to introduce cool air from downstairs and vent into the room or attic.

All right, all right!

it's still a mess, didn't want to show till I got the place cleaned up a bit.

How about the cooling?

If it were mine I would pull air from the room and vent it out. I don't think I would like the idea of pulling air straight from the duct into the electronics rack. Perhaps introduce some added venting from downstairs into the opposite end of the room and you have yourself a good air exchanger for the room. .

so ok to vent to attic? that means equipment semi exposed to attic environment, but should be ok right?

I don't know if this is any help, but in my build I'm actually installing a high powered fan from FanTech which I've installed in the attic space above the room. I don't have my room completed yet, but in theory it should pull heat off my equipment and at the same time circulate air throughout the room when on. This is the cheapest option I found without having to install ac which would have been expensive in my case. It won't cool the room, but my hope is it will keep it at a constant temperature when it's not the dead of summer.

I don't know that circulating air will help, the problem I'm having is the room is getting much hotter than the rest of
the house. it has a return and two vents in there but the heat from rack and projector not to mention 4 bodies makes it warm in about an hour.

I need a way to get heat from rack out of room or heat from the room either dumped downstairs or to the attic.

The guy that advised me said these types of systems are often used specifically for what you're describing. By placing the nozzles within your av rack and above your projector you pull the heat directly from those areas and suck out it through an attic vent somewhere in your attic.

In my case this system is doubling in pulling heat from my components as well as moving air through the room. (that's my hope anyway.) :-)

I'm not particularly familiar with HVAC, but it seems like pulling air out of your room and into the attic will also pull the cool air out as well, even if your ducting is located at the equipment rack and the PJ. But, it seems like the cheapest and simplest thing to try. If it doesn't work, you won't be out much.

EDIT: Are the rack fans on a thermostat? If so, you could try moving one to the back to vent into the attic as you suggested. The way you have the vent in the bottom open to the room, and then maybe put an exhaust into the attic at the top (in the back) seems like it would keep things cool even when not in use. Again, seems like a cheap fix you could try.

I know this wasn't on your list of options, but could you put an electronic damper in your supply and return and add a thermostat (or even a remote sensor) for your theater? That way you could cool the room independently of the rest of the house.

Another option might be adding a dead vent that pulls cool air from another room and exhausts it back into the house using your existing ductwork. Without knowing more about the routing of your duct work, it's tough to make many recommendations.

No, fans have to run pretty much constantly to keep it all cool. I experimented with slowing them down, but it got hotter than I would like in there. The Onkyo is known for it's heat generation and add up the emo and the playstation, well there's a lot of heat coming out that cabinet..........

So are you saying(which is what I'm thinking) that I should pull air from the cab
and vent to the attic? it's the easiest to do, and should pull air from the rest o the house for any air removed to the attic......

Wait, when the HVAC comes on will it overpower the fans in the cab and pull attic air in the cab? This would be bad...

How can I cool this Room!!?
post #86 of 614
I don't think what I'm using is exactly what you're looking for, but my fan that I have mounted in my attic pulls at 320cfm. it comes with a speed control meaning I can run it full power or slow it down during the winter or when it's only the wife and I in the room.

I don't have hvac in my house so again I don't fully understand the return systems and all that. Sorry I can't be more help.

I was thinking use your existing fans and setup your rack to pull room air in, and exhaust into the attic. I don't think your HVAC will overpower the exhaust fans in the rack because they are only creating a negative pressure in the rack as opposed to the entire room. However, this would just be a test using your existing equipment. If it works fairly well, then you might consider upgrading to a higher cfm fan like mhadley20 is suggesting if you feel like this might fix the issue. Otherwise, you haven't spent much, and you can look at HVAC changes.

I'm sure there are reasons that this is bad from an HVAC standpoint (e.g. you have to replace the air you exhaust into the attic), but it certainly seems like its worth a try.
post #88 of 614
I guess I am making an assumption, but you have an adequately ventilated attic? If so you should have little problem with venting to the attic. Since your room is in the attic anyway you will be pulling the hottest air in the house through the equipment rack and expelling it into the attic. A bit of careful creative ducting should provide adequate protection to the gear. I would think a larger fan with lower rpm would be less intrusive than a smaller one would.

During the winter you would want to have a system that you could block off and circulate the warm air back into the room. I am sure there are other ways of doing it but if I was doing the work I would go this route. Lucky for me my theater is in the basement where it stays cool constantly. That makes for some nice summer viewing.

BTW. Nice build. I am envious of the way you have built out your space. Nice work.

This is kinda what I had in mind the HVAC could prob keep up without all that heat pumping up there constantly.

On the pic you labeled(thanks for taking time) yes the bottom gap is the inlet, the top two gaps are for PS3(now filled) and xbox360(not sure if I'll actually intall). All in all I'll probably try venting to the attic.

The rack has a back door. I'll remove back door, cut in the rack fans, add cool air inlets like you suggested around each component probably. This should approximate a cross flow cooling. I don't think it will pull enough air to affect the room but we'll see.

I'm also going to experiment with the HVAC, it has a setting where I can turn the circulating fan to ON instead of AUTO, maybe that will help.

Rob thanks for the kind words! Its been a long time coming, I've been in the new house almost 2yrs and just got to see/hear it last week.

Now for the endless tweaking which is where I need help from "My People!"
