Welcome to my theater build thread. I’ve been reading lots of other build threads here and have absorbed a world of good information that is helping to feed my design. First, some background. Some of you are probably wondering what in the world “Ginky Weeds” are. Simply put, it’s a term synonymous with “The Boondocks”.
We live in the country, but within easy driving distance of reasonable shopping and restaurants. Importantly, including both Menard’s and Lowe’s stores. We’re on five acres of land with neighbors, but none in close proximity, so no concerns for noise complaints from them. We bought our house in 2007 and it has taken me this long to begin the HT because a) we had a water problem in the basement soon after we bought it and had to install a waterproofing system, taking this long to gain enough confidence in dryness to finish the basement; and b) a bathroom and two bedrooms were the first priority for my wife. With the bathroom complete and the bedrooms well on their way, it’s now time to start the theater. Plus, I’m a planner and needed a lot of time to research aspects of design, construction and desired electronic equipment.
I have collected most all of the audio gear required. I’m planning a 7.2 audio configuration with Klipsch Heritage LCR speakers (La Scala I) and a pair of Bill Fitzmaurice THT subwoofers located behind a screen wall with acoustically transparent screen. Surround speakers are also Klipsch Heritage (Heresy I). Electronics include Sherbourn PA 7-350 amp (7 x 350WPC), 4Z-75 amp (150 WPC for subs), and PT-7030 processor. The remaining piece required to complete the audio gear is a CD/SACD/DVD player. I’m planning an Oppo 103D for that function, which also leads to the video side of the plan. With the Oppo source I’m planning a projector with lens memory to illuminate a 120” wide 2.35:1 scope AT screen. If I had to buy today, the PJ would most likely be a JVC 4910. But I’ll be watching with interest this fall as the new models for next year are announced. New offerings could change my selection by the time I’m ready to install the projector.
The space is choppier than I’d like with more doors in the room than desirable. Unfortunately, I think they are pretty much unavoidable, since they provide the only possible access to those rooms (furnace room, storage room, mechanical room, and bathroom) as you’ll see in my preliminary Sketchup designs below. The basic HT space is roughly 18’ wide by 20’ long to the screen wall with about 4’ behind it and an 8’ ceiling. I’ve talked with The Soundproofing Company about sound control and am planning a “room within a room” to minimize sound transfer, including isolation clips in the ceiling, on one of the walls and in wall to ceiling interfaces. Also two layers of drywall with Green Glue sandwich. Note that the sketches do not accurately reflect the surrounding walls. There are poured concrete walls on two sides and a 2x6” load bearing wall between the HT and the bedrooms/furnace room. The area above the theater is the living room and kitchen, so I need to be as careful as possible to control sound transmission through the basement ceiling and living room floor. Here are my first attempts at design. I’m not real swift with Sketchup yet!
This doesn’t show the challenge of existing HVAC ducts that I want to redesign/reroute, especially in the stage area above the screen wall. Here’s a picture that will give you better idea of that challenge. The ducts are at the far end of this picture. Ignore the mess, it's a work in progress!
So in addition to building a dead vent system for HVAC in the room, I’m hoping to replace existing rectangular section sheet metal heat and cold air return ducts with insulated flex ducts that can be relocated up and between the ceiling/floor joists. I also need to decide on whether to put a door at the entrance to the hallway to the bathroom or to continue with “room in a room” all the way back to the bathroom that then requires me to deal with soundproofing two doors instead of one, as shown in the existing sketches.
Once I get those issues sorted out, I’ll feel in a better position to move on to some of the finishing aspects. I guess that’s enough info for a start and sorry to be long winded. I will appreciate your inputs/critiques and I’ll especially appreciate those shared experiences that help me to avoid unforeseen problems!
