THE DEVILS IN THE DETAILS


Budget

Oh the budget.... well I guess its going to be what its going to be. I will be tracking it like I have other renovations.... down to the penny. We don't have a fixed amount in mind but we are both pretty “thrifty”. That being said I will not cheap out on inferior products just to save a buck.
The majority will be DIY except carpet and muddling / taping

Thanks for joining the ride!
When I saw your screen wall it was immediately copied and pasted into my love it list.
Although not shown in my sketchup drawing yet (still trying to figure out textures) it will be just like yours with rock wall and led lighting.
Only difference is I am doing a AT screen

Thoughts on Reducing Screen Wall Depth

Didn't' want to take over Speakers behind AT screen - Worth it? so I copied over the conversation on trying to reduce the space that I have behind my AT screen.
It is currently is drawn at 24" from wall to wall. The speekers shown are Mackie C200's for dimensional reference.

My UXL's are 22-23" and easily fit behind my 25" space. Subs are real issue, but going DIY with subs leave many options.



I've also seen cabinets stick out beyond base of screen housing subs. If there's a will, there's a way.

17" diameter units would sure help reduce the depth I need
What about DIY enclosures to reduce it even more?

The only part of the screen wall that is AT is the screen its self..... how will that impact the potential sub locations?

Most AT screens have false walls with friction fit panels surrounding the screen. The panels are covered in AT fabric. Is your's different? Do you have cabinetry or something like that surrounding the screen? If so, that will affect sub placement. I would think the cylinders would be out if the material surrounding your screen is not AT. I would look at front firing DIY subs. You could place one on each side of your center speaker and put them on a stand so that they are behind the AT screen like this:

Currently an undeveloped space but my plan is to do a front wall like this:





But the screen will be AT and all front speakers behind

Here are a couple of additional views of the screen wall

Ya I went a little crazy in sketchup and drew right down to the studs in a lot of places....... Glad a did as I discovered a couple areas that needed a closer look

Any feed back is appreciated


Top View ..... bit of an angle

Well, you can close in the sides, but as JVoth mentioned, you're going to be restricting speaker and sub location. Most screen walls are fully AT, since even the masking panels on the side are AT.

You also want to be careful with how close you have your speakers to the back of the screen. Too close and the air pushed by the woofers can move the screen, I'm told.

Finally, you'll want to "toe in" your speakers and having them as close together as you show does make that slightly trickier. You'll have more wiggle room if they are closer to the side walls, and blasting through the AT side panels.

Yes this is some thing that I have been looking at for a long time. In the image below I drew the Dolby 7.1 recommended angles and THX viewing angles. As you can see the viewing angle is good but the L/R is to narrow. This is partially due to the seating distance... I think its to far at 150" for a 120" diagonal screen (105"Wx 54"T) but this is a WAF thing at the moment..... chair creep in the future
At the moment the "wow" factor and it being something different is winning out. I hate to say it as typically I am a very practical guy but "pretty over practical".

Good point, I had just plunked them in there as place markers, any minimum recommendations out there?

How much "toe in" is needed or is it dependent on the speaker? The Mackies have a 90 degree horizontal coverage.

One baffle wall design that @BrolicBeast posted, The Beast, Unleashed , has the speakers well with in the perimeter of the screen, and "toed in" at a pretty good angle. Its a 144"W 16:9 at 13' 5" to front row seating (1.1x width) I'm currently at 1.4x width. I'm pretty sure he is doing fabric on the front wall...... not a lot cause his screen is HUGE but still AT front wall.

One thing that I also debated in length is the 16:9 vs 2.35:1 vs 2:1, 16:9 at the moment is the winner, but 2.35:1 would really help with this speaker placement decision

The generic advice that I hear is 2" from the screen. But it's not really that simple, since there are a number of factors that come into play. For instance, if you have a perforated AT screen, then that type of material does tend to bounce back more of the sound than a woven screen and if you are too far from the screen, then that can cause problems. For woven screens, if you are too close than you might be able to physically see the speaker if it's not black and the rest of the area behind the screen be black.

I'm not an expert on this particular subject, though, so I can't really say anything definitively.

One link, though: http://arqen.com/acoustics-101/room-...ker-placement/

That's an excellent series on setting up speakers and it includes quite a bit of info on placement. No mention of AT screens, though, since it tends to be focused on music vs theaters.

I had an excellent article on why you should toe in and how much, but I cannot find it! In general, though, it will be dependent both on the speaker and what kind of acoustic treatments you have and what kind of soundstage you want. If you're not getting a baffle wall developed by a pro, then the best advice appears to be to just experiment with the toe in degree and see what sounds best.

More than likely I'm going to have mine directly facing the MLP, since they will be so far apart.

EDIT: The article was shared by @Mfusick from his Dropbox page. I don't know if he wrote it or not. I also don't know if he intends for it be shared widely or not, so I won't link to it. Maybe he'll stop by and clarify.

Mike's okay with sharing his article on toe-ing in speakers, so it's here: Setup of Speakers (PDF)

It's excellent.

Well that was a crazy three hours.........
Thanks to my cousin we just move about 25 ft of my main heating duct over to the other side of the main support beam
Reconnected the existing feeds to upstairs and re routed a couple.
I still have to tape all most of the seams and do some temporary connections for the basement ducts
Have to say what took us 3 hour would have taken just me 3 days, and I got a family discount on material and labor
To tired right now but I will post some pictures and more details in the following days

I didn't write it. I acquired it. I can't take credit. But yes it was decent. I forgot where I got it. Probably another thread, as I have seen it linked before. But I do some emailing too might have got it there.

Waterboy77,


You'll not have to worry about how close the Mackie C200 are to the AT screen You can have them right up against it and you won't get any movement. The ports are plenty big on the Mackie C200 and I've never seen them move my screen even though they are right up against the AT fabric. Also you'll likely cross them over at 80hz or there abouts - and you'll probably never see the 10" driver move much at all - even at reference levels.


You will want to toe the Mackie C200 in. I personally like them aimed at the center seat position.


I'm still happy with these Mackie C200 --- with Audyssey mutiXT32 engaged and for the price I don't know how you could really beat them - even with DIY. Street price is $170 shipped at nearly any bigbox movie store with the recurring 15% off coupons that are generally available on any given holiday.


I got compliments on them from some of the KC home theater crawl folk. They far outperform their pricepoint, and excel for a very inexpensive cinema speaker. I've been around the block on the home theater electronics circuit and found I think a practical and reasonably inexpensive setup like the Mackie C200 really delivers to levels, and beyond, that general enthusiasts seek. Yes there are better speakers, and some might want or need more --- assuming the requirements of above reference listening -- that's fun for a quick demo --- but really I'm never going to listen to a full movie that loud. (at least I don't think so) If money was no object, then something like JTR would be my absolute go to (something like @dlbeck 's theater with all JTR speakers is nothing short of phenomenal)---- but if funds aren't unlimited, I'm satisfied with where I landed on the price to performance scale.


When @Scott Simonian visited from CA for the recent KC Home Theater tour, he and @Luke Kamp, and I , and a friend of Luke's watched Gravity at -3dB from Reference and that's the loudest I've actually ever watched a full length movie in my theater. I thought the sound was great and didn't notice a single weakness from the speakers the entire movie. The center channel voices sounded crystal clear - no small boxy sound that typically spews from inexpensive or overdriven speakers. I have no reason to listen to a movie louder than that. In fact, though it was fun and sounded great, I typically wouldn't even listen that loud -- preferring more like -12dB as my typical go to volume --- of course with the subwoofers running 6-15dB hot - depending on the movie. When a scene that is really cool arrives, sometimes I'll rewind and pump the volume -- but for the full - movie -- I don't need it at reference levels.

Hey Archaea, Thanks for the tips on the speaker to screen distance.
Any thoughts on my plan? Open to any and all suggestions

Things have been crazy at work and by the time I get home I'm to tired to even look at my computer
I haven't even had time to post pic of the big HVAC move yet

One day I will start the new theater....... one day..... THAT DAY HAS ARRIVED

Hvac Move

So final taking the time to post the pictures of the HVAC trunk line move.
Big thanks to my cousin for coming out and getting this done with the family discount price
The big reason I wanted to move the line is to remove an ugly transition / 90 degree turn that would have made for terrible bump out, for symmetry in the theater area and to center the ducting on the beam and the columns
For some obscure reason I can not find my before pictures


The closes I have is my plan with the HVAC added




the removal of the old run started




The old run out




New transition piece




The new line in
Its a little further out than I wanted but we had to clear a gas line at the far end
Also had to do a spur of the moment reducing portion.... measure twice








He also left me a bunch of parts to finish up the basement heating ducts and a new cold air return
I also need to finish taping all seams

Decisions Decisions

I could really use some feedback on a decision I am trying to make on design services vs. DIY


Lately I have been questioning my design and lack of knowledge on room acoustics. So I reached out to @Nyal Mellor on the services that he offers. We discussed the costs associated with the five core services, acoustic plan and design review. He is great and answered my questions promptly..... I hope I wasn't to annoying.
I am not baulking at the price as it seams very in line with the time an effort that would be required to put together the plans and design. I am not posting the costs as I do not know if that is allowed.


My dilemmas are:
  1. I am not a audio/videophile, not having heard a really good system to say WOW I want that. Trying to learn but I have no real reference
  2. Given the large open non-dedicated space that I am dealing with, treatment in general will be a different beast that isn't discussed a lot
  3. My ceiling..... I insist on a drop ceiling. I know, I know bad idea but access has always been important to me. That being said a cloud/modified ceiling in the theater area could be looked at
  4. Screen wall..... I love the look of the rock wall that @deewan has but he has his speakers out in front where as I want to hide them behind an AT screen. This posses a problem with meeting correct angles and how to treat the cavity that is created. Most screen walls have AT fabric around the screen so acoustically the cavity is part of the room and treated different.
  5. Surround Speaker locations...... With the open concept I haven't fully figured out the best placement of the back surround speakers as there is no wall. They will probably have to be ceiling of soffit mounted.
  6. I am thrifty... (not a dilemma but a factor) Many in my family call me cheap but that's miss guided. I trend to way the pros and cons on major purchases intensively and try to make the best informed decision. If an expensive tool or piece of equipment will notably improve function, safety and results I will buy it. (hopefully on sale ) I will also reuse / recycle whereever I can as I think in general we are a wasteful society..... no I'm not a tree hugger, but every bit we can reduce waste the better.
So with all that the core question is:

With some of the challenges my space / design faces would a health financial investment to a professional design service yield the return that would make it notably better than a personally researched solution?

Hope it not to much rambling, please help as hours of sleep are being lost on this

One day I will start the new theater....... one day..... THAT DAY HAS ARRIVED

I think professional design services yield benefit.
So do capable speakers, and all the more for capable subwoofers.

However, I think that with just some homework and reading on the forums (something you seem willing to do) you can derive a enjoyable experience without the expense of professional services. (not that professional services don't have their place)

We recently hosted a KC home theater crawl with five different hosts in greatly differing rooms and with greatly differing costs of equipment/room. Two were professionally designed and setup, three were not - I enjoyed each and every room on the crawl.


Craig John implemented a dead front, live back room design, and it remains, perhaps, my favorite room treatment for sound of those I've visited.

As for drop ceiling. Look long and hard at Certainteed Theater Black F tiles. They work EXCELLENTLY, 3% light reflectivity, and .75 NRC. Put R30 pink fluffy above them in the floor joists and you'll have a much higher NRC. They don't rattle either like typical white drop ceiling tiles. My original white ceiling tiles rattled like mad everytime the bass hit. My certainteed tiles are silent. No changes to the grid. If I had to describe them, they are basically OC703 tiles with a light absorbing black material on one side.

My two cents, and FULLY understand you may have different standards or tastes so feel free to take or leave these....

1) Screen Wall - The rock wall could be done with an acoustically transparent screen. I can think of a few really cool designs you could use. Buy or build in-wall speakers. And I'm not talking about the normal big company in-walls. I'm talking stuff comparable to the C200's you mentioned above. This would provide you with the look you want and the performance you desire.
2) Nothing wrong with a drop ceiling. I would stuff insulation between the floor joists to contain the sound in the room. A few diffusors could be used instead of the normal ceiling panels to prevent over absorbing sound (if needed). This can be done afterwards, one of the benefits of a drop ceiling.
3) Nothing wrong with how 'cheap' you are. I am exactly the same way and that's why I spent less in building my room than the quote I received for acoustic help. I'm sure my room could sound better, but if it was 10% better than what I designed myself, it isn't woth it in my eyes.

Long story short, I don't think any of the problems you mentioned above are going to be deal breakers. I think you can continue down the full DIY path with the help of the amazing people on this forum.

Thanks for the feedback. I am certainly willing to and already have done lots of homework and reading. Just need to make better notes
Do the five hosts have build threads I can go through?
What did Craig John do for treatments?
Do you know what their factors where for using and not using professional services?

I already have the drop ceiling purchased, I love the look of it and have had many compliments on it in the area that I have finished
http://www.snapclipsystem.com/

That being said I am concerned about the reflective nature of the product (light and sound) and potential rattles.
They are coated 1/4" MDF so no absorption at all. With this system I only lose 1.5" of head room

This is an image from there web page


As deewan mentioned if I find it unacceptable I will switch out or modify the tiles that are an issue, playing this one by ear

I don't doubt your ceiling rattled with all that power your pushing

I would love to hear about the cool design that you are thinking of!
One key reason for AT is to hide all the speakers, even surrounds will be hidden in columns

Yes my plan is to put insulation between the joist and reviewing drywall on underside of floor above for foot fall.
My gut is telling me I will need absorption on the ceiling but I indent to measure the room and decide later. Like you said that is the nice part of drop ceilings

Thanks for the feed back deewan, what was your deciding factors for not going with the quote you received?
FYI your one of the amazing people on this forum....... (yes blatant suck up)

I'm solidly in the "DIY 4 Life" camp, so I'll never completely dissuade somebody from going that route.

But... even I have to admit that going DIY for various design aspects isn't really for everybody. Here are two ways that it can absolutely work:

1. You are okay with "pretty good" results, which can be gotten via some relatively generic advice, and are willing to spend some time to get it
2. You want stellar results, but are willing to be staggering amounts of time to research and test as you go

I think a lot of people are actually in the first camp but don't realize how good the sound can be with just a few simple treatments. That'll never satisfy an audiophile, but MOST people aren't audiophiles and have never even heard an audiophile-grade system.

The latter group is honestly pretty rare. Most of the people who want top-notch results will find that their time is much better spent doing something else and hiring a pro.

Keep in mind the time factor, though. No DIY solution is going to leave you as much free time as paying a pro for a plan.

I'll have to make some drawings so you understand what I am thinking for the AT screen.

When it came to my room and the acoustic treatments, my decision was pretty easy. I had spent over a year researching acoustic design and felt I had a good idea what I needed to do for my room. When I got the quote for the professional help, I had sticker shock. The amount for just the design was at the upper end of what I wanted to spend for the design and gear/equipment. Don't get me wrong, I am sure it would be worth it. It just wasn't worth it to me since I had already invested time and the things being communicated to me about my room were already things I knew.

Hey granroth, I am also in the "DIY 4 Life" camp, but my wife would say the LIFE part feels like a LIFTIME
I will tackle all Reno projects except mudding/taping and Carpet

I think I would fall into number 1, with a mild case of 2 in regards to test as I go. (once I decide on a testing means).
As noted I am not an audiophile but don't want to "settle" for good.

So which camp would you say you fall into? Given your attention to detail and the amount of testing you have done so far I would say number 2


Did ever entertain the use of professional design services?

Thanks deewan, I look forward to seeing your thoughts. Above are some of my Setchup drawings that show the screen wall and speaker layouts. the Sub hidden in cavity is not shown as I struggle with this also.

So was the year of research the trigger for your change to your room?
Besides AVS and the wealth of knowledge here, what other sources did you go to for your research?
I have Toole's book that I need to start reading in my spare time (or lack of)


At what point would you all say that construction should stop to address acoustic issues?
