Dunston Cinema

My name is Danny and I have been a lurker for about a year now. Im currently in the Coast Guard 18years and will most likely retire in this home. This forum has a lot to offer and I hope I can add to the many great home theaters I have seen on here. I am located in Gloucester, VA and we bought a new construction home about a year ago from Ryan homes. The thread name comes from the Neighborhood I live in. Yeah not very creative but its a start. My goal is to have a decoupled room with good sound isolation. I like loud music, watching sunday games/racing, Netflix series, and movies. As far as budget I don't have a crazy one. im thinking 10-15k. I will be DIYing speakers and building the room.


Construction of the HT will begin in about 2 month, but I already have ideas of what I want it to look like. I like clean lines and a modern look. it hard to find examples of this. For now the room is a blank 24x14 "storage" area I want to build for my family of 5.


Room size
14x20 beam in the center of the room.
main chairs will be at 10.5-11ft from screen


Seating
5-7. this will depend on how the room will fill out and what chairs I decide to get


screen


I plan to do an 130" AT screen 16:9


surround
with a 5.1.4 or .2 atmos set up. I will wire it for a 7.2.4 incase


I haven't decided on equipment because that will be the last thing I will put together.


Any input will be appreciated. This is all I have for now. ill load up more pictures of the actual room tomorrow

Any chance of making the room longer by minimum 3 feet so you can have that extra space behind the last row of chairs?
Putting them directly on the back wall is no good for the sound.

How tall is the room? And how much is height is there under the beam?

I gather those are concrete exterior walls? And that there's a beam over the entry wall, and support posts
embedded there?

concrete on 3 sides, beam is over that entry wall with no supports. it sits on top on the concrete basement. I can go any longer because I will start cutting into the hvac and hot water tank area. I need to leave some room for that and create a wall. the rear speakers I plan to recess in to the rear wall. I may have more room if I don't do a huge screen and move everything up a little.

room is 8ft high I think. I will have to measure it out again. other idea I had was to scrap the rear row and just do a bar top with chairs. this will give rear more room

@Tedd the room in this link is very similar to mine for the exception of being about 1' shorter and 1' narrower.

My first thought was The Signal Hill Theater.

The "5"-7 number caught my eye, as a one row five (narrower style) seat room is a concept I expect to
implement for my next theater. Here's quick concept drawing of that. The whole vibe of that idea is a BIG
acoustically transparent 16x9 screen, with horizontal mask for scope, and keep the seating off the room
boundaries, and get that one perfect time aligned seat. The beam could be partially disguised by a cloud
ceiling, which would let you acoustically treat the ceiling, and put the lighting and overhead speakers in the
backer boxes, within the room's isolation shell. Another desire is to put the projector in the rear wall, in a
hush box.

I do want a big picture and with a family of 5 this would work. never thought about the room lay out like this and the mechanical room. What narrow seats would you recommend? I was looking at these https://www.htmarket.com/htdesignsomersetblack.html but they are almost 13' wide for a configuration of 5. I might be able to wiggle about another 1.5' width in the room with your drawing.

Most people never consider such a layout. The two/three row and riser layout is pretty much the gold standard, but there's a lot of pluses
for a single row layout, if one starts to look at such a layout.

I would aim to take the extra width.

Salamander has some narrower seat designs, such as the Matteo.

I am exploring such a layout for myself, come a retirement move. That means I have no room to design around, so that means I need to
leave options open. I could see myself simply pairing up a pricey 4K pj and five commercial theater seats to make a narrower space work.
That would be a 10' seating arrangement. It'd also be pretty inexpensively cost-wise, but these days, I look at that as budget for some
other feature, like masking. On the very bottom end of seating, I could something like a single row JBL demo room (but in much darker fabrics).
On the upper end, it'd be more Waterfall Audio style if I wanted to invest budget in really good seating like Salamander .

took the dimensions from the salamander matteo seats and put them in the room. Looks promising and I modified the room a little bit with a new lay out using your idea. Looks pretty good. Rear space for the seats is at 3ft and to the screen wall it would be 12.5ft. walkway in between the seats measure about 2.8"


Now I really have to decide if I want to ditch the whole raiser 2 row seating for this. I like that look but this would save me money and would be easier to build

It does boil down to just how much use those extra seats are worth to you, and how often they'll be filled? Now that doesn't mean you
can't bring in two more seats and fill in the ends. Those would be audio compromised occasional seats, but your first drawing
has but three seats not compromised. All in the second row have several issues.

Not only is it easier to build, it's cheaper to build. Put the pj in a hush box in the rear wall, and bring the electronics rack out of the room, the
cooling needs drop significantly. which means it's easier to not have the HVAC introducing noise into the room. (A low noise floor for a home theater,
should be a priority in design.)

So what does the savings get you, if reinvested in the room?

The extra seats don't mean much to me as I know they wont be filled 90% of the time. We are only a family of 5 so I would like to have atleast enough seats for all of us. I can probably do just 4 and have the little guy on a comfy bean bag...lol. He wouldn't mind. The saving would go to something else. Im pretty much set on a 7.1.4 surround and a quality screen. The PJ im looking at now is the Epson 5040ub. I don't think ill go super crazy after saving money on the seats and riser. I just want a set up that looks good and sounds good. Not looking for a highend 30k+ build here.

I think the single row would be a pretty killer setup then. The fifth seat does have value, as it means you can have the ideal time
aligned center seat. You don't get that with 4 seats.

Price aside, there's no reason one can't employ good design practices, in a budget room. Mix in
some DIY skills, and not having an overly large space, then things just get very interesting in
just how much a lower cost build can push a larger high end room.

Still need to figure out what I’m going to do to insulate around the duct work in the room. Do most people just build a osb box, gg, and drywall? Room is 13’4.5” x 19’2”

you could remove that 2x stuck to the bottom of I beam and span the bottom with just the drywall. Would save an inch of head room or more depending on if your were planning on running clips and channel on the beam. I would hang a double drywall box off of an isolated ceiling structure.

To answer your question what duct work?

Do I just insulate around these or do some boxing sound proofing around them. I also marked of a 100” 16.9 and 2.4 screen. This is the size I’ll use for a 11ft viewing distance. Big I haven’t put too much thought about the beam just yet

Trying to decide which way to orientate the room. Door in the front of the room or the back? Plan is to have 2 rows of 3 chairs. Please help

Quick questing on running your speaker wire. Do most people just run this wiring straight thru with no conduit? I bought monoprice 14awg speaker wire and plan to run it tomorrow.

If your speaker wire is rated for in-wall construction then you can run it through the walls. Just make sure that it's not running within a couple feet of electrical cables if running parallel, and try to cross High Voltage to Low Voltage wires perpendicular. This is so that your electrical wires do not cause interference.

A lot of people like to install conduit to help future proof the room in case another wire needs to be run eventually. Generally though you leave the conduit empty, and run the wire outside of it, while you have access to outside of it.

Run a 2" conduit to the projector, especially if you plan to live there long term. HDMI specs change over time, and it doesn't take that long. With 2" conduit you can run more than enough for whatever your projector needs and change them out as technology advances. Just don't run 120v through it.

I ran 1 1/2", large sweep, conduit from the rack to the projector that way I can run whatever I need now or in the future.

So before I go buy 40 pieces of 12ft hat Channel do I really need it? I have already installed ib1 clips but I can take that off and just leave the once on the ceiling so I can add channel to that. Click image for larger version

ID:	2701888 my room is completely a room within a room in a concrete basement. Reason I ask is because it is already 13’5 wide and if I don’t need it the. I’ll just order the 5/8 drywall and finish up. I am using ib3 isolators on the top. Comment people!!!!

Green glue is already here

If the framing is truly isolated and in front of a foundation wall probably not. I see the framing is sitting directly on the concrete, that is not truly isolated. Placing rubber mat under the bottom plate would have solved that. Leaving the back of this wall unfinished is probably more of a problem then deciding channel or no channel, any wall vibration whether on a channel or not will fill up that space with sound and send it upstairs. The way to address that is to use clips and channel on the theater side and put two layers of DW on the backside. Or do double wall framing with drywall on the backside.
