Building a Home Theater & Listening Room

My wife finally parted with a portion of her terrace garden and let me build a home theater.

First off all I find myself very fortunate to build a room that can be dedicated to music listening and watching movies. The room will be 3.96 meters wide, 7.38 meters long and a height of 2.7 meters. So with a little more than 29 m2 it's not a big room at all.

We live in a duplex penthouse (5th & 6th floors with terrace rights). So, traditional construction methods are a bit difficult. I plan to take the prefab route.

Proposed HT Room area.

So 13 x 24 x 9 roughly? That's not too bad, a medium sized listening area. At least you won't need too much amplification for that.
 
curious, which country? and those frefab walls, they are concrete/cement? it will be interesting to see how you do the wiring! are thinking about 5.1 or 7.1 or something like that?

Interesting project, keep us posted. Did you think about what type of amp/avr and speakers you will be using?

DesiPower,

I am located in India. The prefab walls are sandwich panels made up of two plain cement sheets on either Side of a lightweight concrete core composed of portland cement, binders and a mix of siliceous and micaceous material aggregate with a unique tongue and groove jointing system.

I will begin with 5.1 setup... the room will be wired for 9.1 though.
I am piling up stuff for my dedicated theater. I have all the kit i need already for this…mix of new and from old lounge...
 
These pics are of the composite decking sheet being fixed... in fact yesterday... the plasterers were skimming the walls and pouring the concrete slab...

I will add more photos as the work progress.








 
Started laying electrical, speaker and signal cables. The cabling work is being carried out by a local guy and someone from my work giving him a hand.

To reduce hum and noise I want to install a dedicated line with only a single ground from the audio / home theater system to the electrical service panel. Don’t want to attach anything other than the A/ V system to this special dedicated line.

Expecting the result to be noise and hum free power with a 'deep black background'.

By this stage of the project, I have already identified the following:

• Placement of all speakers
• Placement of A/V components
• Placement of video source
• Lighting needs
• Possible future enhancements
• Thermal Insulation & Acoustic Treatment

BTW I have provided a frame also…for supporting the screen.

I will try and post pics if there's interest...as soon as i work out how to do it....!!

I have all the kit I need already for this…mix of new and from old lounge... not top end by any means...but works for me...

Looking nice, You on AVS also?

Looks like a set up derived from over there, I like to stop in and look at stuff that is in that awesomeness range on a lot of things there.

Gonna be some insulation for sound damping in the ceiling and walls I'd figure.

If you're this far along on that I'm sure it's all ready covered.

Thanks MongGrel for remembering the thread on AVS.
I am also on couple of other audio forums... where I share my hobby and passion with other fellow members.
 
looking like it's coming along nice, definitely interested to see the final product. it's moved along quickly and looks good man.

Thanks purbeast0,

The progress in construction:

Framing work in progress for rock wool slabs…



Checking out my old screen…

16:9 screen pulled down…



 
Framing work completed and AV cabinet in place…cabling almost done but for one sub signal cable. Got 20 Rock wool bags delivered yesterday.


There was a leak from one point of the slab joint side…. getting the pressure grouting done today.

Entry door to the theater on the left:









AV cabinet built into the window: Ceiling panels getting ready:






Insulation panels being fixed:










 
Paneling of rock wool frames almost done:










Steel trusses being enclosed in wooden beams:











Back row riser in place:





Front row riser:





 
Got few sample seats today... my folks liked the red one, the design part of it and not the fabric though. Actually it is wider by 2” and comfortable than the other two.

Decided to order seven seats with individual arm rests… and different cloth material which I have to select.







​
 
Slow progress, but progress nonetheless. Tough to get things done when you are on carpenter’s schedule, but I'm grinding along. Got most of the ceiling done, preparing bass traps and acoustic panels…



















 
Hey guys!


Here is an update on the build… I have spent countless hours on there reading and learning since I started trying to figure out what I wanted to do 6 months ago. It’s like a fun project for me... The entire room needs a good deal of sound work. Even still, I'm happy with how it sounds to my ears after watching a couple movies... I just need to contain it better for now.


It's the old saying of "measure twice, cut once"… live it, learn it, love it the downside to that is since I have never done anything like this before who knows what I missed or what I underestimated on.

I think you may have messed up on those seats man.
It's cool to have "movie theater seats" but 2 Love Seats (Or couches) are far more comfortable. Especially decent ones.
Your choice but especially if you're married, movie theater seats like that are not intimate at all.

Also like above poster said, neons? I'm not sure how they look while watching though, do they distract from the picture at all?

A home theater is always an ongoing project. Updates, upgrades and replacements are inevitable. My home theater is a do-it-yourself project... I am preparing a true Home Theater element vs. home viewing environment. I wanted to retain the windows and door to make the HT a part of my home... not a separate and isolated room.
I do plan to keep those windows and the door... for acoustic purposes I have build separate door and windows from inside.... to blend with interiors.
I know some guys say all windows should be eliminated, etc., but I really think they could add a nice touch. What’s attractive about them is that they let you see into the theater room from inside the house.

I chose not to design a contemporary style theater. I wanted my home theater to remain true to my great memories of a traditional movie theater.

The seats come with certain features like, push back springs, easy to fold; soft drink holder handles... the darn things are pretty comfy. If I had the room, I'd go with comfy chairs over theater seating; however... there is a certain novelty about having actual theater seating I guess. It's about the look you want, the comfort you want, and budget of course!
