INTRO & BACKGROUND

Well, alrighty then! Here we are at the tail end of one story--the dismal crash & burn of Synyrgy Cynyma's initial launch--and the trail head of another. Today we find 1_sufferin_mind deep in thought with his pencil sharpened and nose to the HT design grindstone. To get my inevitable negativity out of the way: all hopes and dreams have been dashed upon the rocks of In-Law Bay. I've been targeting a full-size, custom-designed room but the current plan has me moving toward new construction with a predefined floor plan.

While I've been graciously allotted two upstairs rooms, neither is of sufficient size for a serious dedicated theater (see floor plan below). The builder confirmed that the shared wall can be removed, but only at substantial cost. I'm hesitant to commit to the design modification anyway for fear of adversely affecting the home's resale value. Besides, creating a single large space merely compounds considerations for placement of an office nook and an audio workstation area for LP cleaning and transcription.

In any case, I chose the 11x17 room not only because it's the larger of the two, but also because it has a relatively uninterrupted perimeter. That allows for good acoustical symmetry and aids equipment/furniture layout. It's my hope that I'll be able to customize the build for HT use without detracting from its use as a bedroom when the house is sold. I plan to add a second HVAC vent (and possible return) to help siphon off equipment heat from the plasma TV, tube gear, AC Power Regenerator, and power amplifiers. I also plan to add at least two 20A dedicated power lines. I would like to have conduit in the walls/ceiling/floor between intended equipment stations for a tidy installation and to ease future equipment expansion/upgrades. Whether or not I can afford an HVAC professional and an electrician's time is another story.

Borrowing from bkeeler's My New Theater thread, I'd like to organize mine the same way--I've added reserved sections for specific topics immediately following this one.
This is my first time tackling a room from bare construction, and I don't have near as much control over the build as I'd like. Please let me know when you think there's a better path to follow, if you'd like to challenge my decisions, or just want to cheer me on. I've been around the block before when it comes to setting up equipment and rooms, but not when it comes to designing/constructing the room itself. The builder may move so fast that I won't have time to include any mods, or they may not be allowed. I'm open to your suggestions and advice!

FLOOR PLAN & VIEWS
(Updated 05JN19)

My top choice, Bedroom 3, is highlighted in the drawing. I initially thought the room was a foot narrower than my current one. Deep depression ensued. Equipment would necessarily play into the short dimension for better SS&I, but that hinders surround placement behind the audience. I've since discovered that the new room is actually a foot wider! That means I'll be able to get more physical channel separation, or sidewall distance. The new room is also four feet longer, so surround placement will now have some degree of optimization potential. My first image of the plan is just an uncluttered view without annotations. I'll be adding some roughed-in equipment/furniture layouts as the project progresses.

UPDATE #1:
Wouldn’t it be great if the main entry door opened outward from the room instead of inward? That would be so much more flexible for speaker/trap placement. We’re checking with the builder if it’s an option.

UPDATE #2:
Here are my latest customization requests for the room

CONSTRUCTION & MODIFICATIONS

Upcoming pictures will let you follow along as the home is built. I wish I could promise specific HT pics, but I’m unsure if I’ll have much control over materials and/or methods to make it interesting and worthwhile. At a minimum, I’m hoping to specify electrical drops and conduit locations.

SOUND ISOLATION / SOUNDPROOFING
(Updated 05JN19)

Other than traditional acoustic treatments like traps and panels, I have no plans to modify the room's structure or build a room-within-a-room. A lot will depend on finances and whether or not the builder accommodates special requests.

This is definitely a topic I'll be seeking guidance on. It would be advantageous to soundproof the floor, because the in-laws will tend to congregate in the room directly below. It would help to know where the diminishing returns are. I think soundproofing the door and vents as much as possible helps more than sealing drywall gaps, for instance. Please set me straight if need be!!

UPDATE #1:
Mr. Poe was kind enough to detail the major considerations for sound proofing/isolation in my original thread. To summarize:
  1. Decouple
    View attachment 10843

  2. Absorb
    Use sound-absorptive materials such as cellulose, mineral wool, and recycled cotton (R13 in walls; R19 in ceiling/floor). The key is to keep the density low. Don’t compress or pack the insulation. There is no data that supports that any other insulation (including the “acoustic” labeled, and recycled cotton) works better. Also, foam (open or closed cell) is superior for thermal but distinctly worse for acoustic. Use the cheapest fiberglass you can find.

  3. Add Mass
    Use dense/heavy materials such as Drywall, Plywood, OSB, and Cement Board. For sound to conduct through a wall, it has to actually move the wall ever so slightly . A heavy wall is harder to move than a lighter wall, but it will still vibrate (i.e. it will still let some sound through). It is best to use two layers of 5/8″ drywall, but simply adding mass does not help block much bass.

    extra_drywall_performance_f_improf_920x450.jpg


  4. Dampen
    Reducing the drywall from vibrating in the first place would make the jobs of the mass, insulation and decoupling easier. This is where Green Glue sandwiched between layers of drywall helps to keep it from vibrating excessively.

    green_glue_performance_f_improf_920x450.jpg
It would seem that the more effective HT sound isolation methods really are cost prohibitive in my situation. Knowing we’ll be moving out of the newly constructed home within 5-10 years, it’s financially unwise for us to invest in a disposable, high-performance theater so close to retirement. We may need to sell quickly, so won’t have time to wait for the right home-buying HT enthusiast to come along.

VENTILATION / COOLING

I plan to convert the HT room’s walk-in closet to an equipment room. My Class-A and tube gear run hot, along with my AC power regenerator, so dedicated ventilation/cooling will be a necessity. I am considering a ductless ceiling unit vented into the attic. The home will be fitted with ridge vents for superior heat dissipation, so I don’t imagine the extra heat load will pose much of a challenge. Thoughts and feedback welcome!

ELECTRICAL

At a minimum, I’d like to substitute 20A circuits for the traditional 15A ones, and have each dual-outlet “location” on a dedicated line to the main box. I firmly believe in running power amps—unhindered by surge/protection devices—straight from the wall. But I’m not as militant anymore about keeping amps on separate circuits. I doubt this old geezer could hear a difference.

So in the closet itself, I anticipate needing three power amp outlets, one main equipment outlet, one HVAC outlet, and a spare. Aside from a normal complement of general-use outlets, the room would have an outlet on the front wall for either a TV or motorized projection screen, floor outlets for reclining HT seats, and a ceiling outlet for a possible projector. Did I leave anything out?

As you have the room upstairs, you are probably at the point of diminishing returns after you have installed sealing strips around doors and perhaps some vibration dampers under the speakers. To be effective sound isolation need heavy mass + an air tight shell (wall + floor + ceiling). Probably you cannot reach that heavy mass and if you tried it would cost huge money, the building could even collapse ... A good read for sound isolation: https://www.jhbrandt.net/resources/ => https://www.jhbrandt.net/wp-content/uploads/2014/11/How-To-Find-Out-How-Much-Isolation-You-Need.pdf

(It is not uncommon to mix up sound isolation with sound absorbtion. It is not the same thing.)

Your advice is in-line with recommendations from others, and I think I’m now dissuaded from considering sound isolation—as much as it will sorely be needed. From what little I know. It seems as if a sealed, solid-core door combined with wall-gap elimination and maybe some HVAC duct treatment just isn’t enough to mitigate inevitably high SPLs. Especially in the bass region. Sure these measures help, but I believe they’d be swamped by sound transmission to the downstairs through the floor and walls.

I’d like to thank you all for participating so far, and think I should let you know I appreciate your input. I hope it doesn’t seem as if I ask your opinion and then go off in another direction anyway. I’d like to improve my room and grow as an enthusiast, so need you guys!

Does anyone have an opinion on, or experience with, configuring a system on the long wall instead of the customary short one?

Other than a reduction in the number of preferred seats, what are the pros/cons of a long-wall system?

How is sound quality affected? Can a superb HT system be set up that way? Why or why not?

On that same subject, projectors can throw off some heat. Some additional cooling or separate zone could be a good thing. Especially considering 2nd floor.

So in the closet itself, I anticipate needing three power amp outlets, one main equipment outlet, one HVAC outlet, and a spare. Aside from a normal complement of general-use outlets, the room would have an outlet on the front wall for either a TV or motorized projection screen, floor outlets for reclining HT seats, and a ceiling outlet for a possible projector.

Didn’t see powered subs on your list. Some of them are circuit worthy.

If you go the way of the motorized AT screen in front of the Revels you could put a TV or some other powered gear between.

Random thought: Possible access to closet from other bedroom. Equipment positioned for easy access from front and back.

A separate zone will be installed for the second floor which I’ll share with my wife. Luckily, she likes cooler temperatures. Maybe I should consider a window unit along with the second upstairs zone and the ceiling unit in the equipment closet. Operational noise levels will strongly influence whether or not a window unit takes up residence.

I’ve asked for extra electrical outlets in the room but was told they need to be a minimum distance apart. I’m hoping to get lucky that one or more of them will be close to the subwoofer(s).

I really, really like your idea for an access door on the other side of the equipment closet!! That’s much better than locating it a sufficient distance from the wall behind, because it’s much more efficient use of space. See the FLOORPLAN &VIEWS section for an update.

A smart thermostat that can be controlled from an app might be handy assuming the zone's thermostat won't be located in your listening room. Beyond that your contractor may have some thoughts with respect to a return line from the room or an additional supply line for better turnover. I can't imagine such a change would be very expensive at all.

It would not bother me in the least to set it up on the long wall... I'd probably prefer it so that I could really spread out my front speakers for the best sound stage and imaging and depth acuity. At only 11ft wide... been there and done that in an 11.5 x 19.5 room... the fronts are right next to the wall.. can't get them spread out far enough...just not that good for music, although fine for movies.

The drawback is likely one row and rears being useless if you planned on using them, which wouldn't matter to me, as I do not care for rears anyway. I put my surrounds in the rear corners. The only speakers I want in front of me are the front speakers... nothing on the side. I do have the Atmos speakers above me just slightly forward... but they are extreme ambient in movies only, unlike what side surrounds will do to mess with what I hear.

I can’t see any upside for home theater.
To add to those downsides Sonnie pointed out ...
- seating too close to rear wall, I.e. worse bass peaks (or nulls potentially)
- smaller screen either limited by front speaker width or projector throw distance.
- projector probably above seating so fan noise more noticeable.
- no room behind for atmos overhead rear speakers in an x.4 configuration.

Definitely good points I did not think about for movies.

It’s an unacceptable trade-off for me as well. Might as well have direct/reflecting speakers.
I place sound quality above video considerations, so don’t mind if light reflects off the speakers or they encroach on the image a bit.

I put my surrounds in the rear corners. The only speakers I want in front of me are the front speakers... nothing on the side. I do have the Atmos speakers above me just slightly forward... but they are extreme ambient in movies only, unlike what side surrounds will do to mess with what I hear.
Do you mean the side surrounds detract from music listening, or that you feel they distract from movies. I ask because of the phrase “mess with”.

If two channel music is more important... there would no question for me using the long wall. If movies and surround are more important... I probably lean towards using the narrow wall.

I tried side and rear at one time... on the back row of seating is where it really messed with me. There was too much information coming from the side speakers that got to me before the front speakers. It was weird. For the front row, for which the system was tuned, it was fine, but there are many time I will sit in the back when we have company over for a movie, and thinking about others who sit on the back row. The rear corner surrounds have always worked well for me. I feared Atmos giving me issues, but it's really just ambient... they are not like the surrounds... at least I have not noticed the same effect. Right now my theater sound is truly transparent from my primary listening position, and pretty respectable from the other seats, so I have no complaints. I contribute the bulk of that to Dirac Live.
