Spaceman Theater build - Page 31

Thanks, TMcG. I thought that might be how it works. Even though it will be clamped under the plate, it doesn't seem as secure as the looped method. What's the reasoning behind it? Speed of installation?

Yes, I'm using 12 gauge wire (which isn't very much fun in crowded boxes).

Thanks for stopping by, Eric. Hopefully, my RedMere cable will get here by the end of the week so I can hook the projector back up. I moved the receiver & blu-ray into the equipment closet tonight, so I currently can't reach the pj with any cables.

My 2.35 screen is 115" wide, which I think translates to 125" diagonal. Viewing distance from the front row is 9'-6'".

I hope to start installing some of the Insteon gear later in the week and will be sure to post more detailed info then.

Well, I can tell you it isn't based on actual room testing or even a room-specific acoustic study. It was simply a treatment program that kept popping up in numerous builds so it quickly found a way into mine. My understanding is that the extra thickness helps with the lower frequencies while the FSK facing keeps the room from becoming too dead by reflecting the high frequencies. My side walls have lots of absorption, so the FSK on the back wall helps balance that. There are other variations that introduce different thicknesses with an air gap, but I decided to use the 4" thickness with the FSK facing. Hope that helps.

Thanks, Austin. I'd like to have the room functional by Christmas (maybe with a missing panel or two). As a temporary setup for the equipment, I stuffed a portion of an old oak entertainment center into the closet. It holds what I need for now and makes things somewhat presentable until I build the swinging fabric panel for that column and a set of permanent shelves inside the column/closet. Although, once I have the fabric panel up on the column, it will be quite tempting to just paint the oak unit black and call it a day. It just doesn't breathe as well as open-backed shelves. I'd have to do some ventilation surgery.

Eric - The screen is from SeymourAV (115" wide 2.35).

Thanks, Landshark. I'm getting close. Major milestone today...all outlets in the room are fully operational so the extension cord is being retired. I still have the Insteon switches to hook up, so I still have a work light in the room, but having working outlets is a step in the right direction.

Trying to get it presentable/functional by Christmas/New Years. It won't be 100%, but at least we can enjoy a movie or two with the family.

A question for the general audience:
I am still waiting for my 35' HDMI cable, so the projector is currently out of order. However, I popped in The Dark Knight this morning to test out the subwoofer. I had a single HDMI cable running from the Blu-ray player to the Blu-ray HDMI input on the receiver, but I could not get any audio. Only after running an audio composite cable was I able to get an audio signal. I'm assuming there is some HDMI setting I need to look at in the receiver audio setup, but if someone could point me in the right direction, I'd appreciate it. It's a Denon 4311.

I was wondering if it might be because I don't have a display connected. Unfortunately, the smallest thing I have with an HDMI connection is a 42" plasma, so I will probably have to wait until the projector is up and running again to check that and to navigate the Blu-ray menus. I plan on getting a small display to put with the equipment anyway. Might have to push that up the priority list.

I tested the Blu-ray on the 42" plasma. HDMI audio output is turned on and I get Blu-ray audio from the tv so it is most likely a receiver setting. I don't really want to disconnect everything from the back of the receiver to haul it downstairs to the plasma, so further troubleshooting will have to wait. Thanks for the suggestions so far.

Next up...Insteon switches and dimmers.

Thanks, JVoth. My bank account and I currently have no plans for a dedicated amp. Not to say that the upgrade bug won't get me (the Emotiva amps sure are sexy), but I'm quite happy with the audio I'm getting now and I haven't even done any calibration. Maybe down the road.

Thanks David. Hope to have finished pics after the holidays.

I moved my seats into the room this morning. Quite a transformation. I think they look good, but the room got small pretty fast. I have my can lights disconnected, so the awful lighting in these pics comes courtesy of the halogen work light. Oh, and Is it too late to put a wide-angle lens on my Christmas list??


The back row looks like it's right against the wall, but there is actually 15" from the wall to the back of the headrest when not reclined and 11" when fully reclined. Still a bit close, but it's all I had to work with.








I'm a little concerned with the gap between the end seats and the riser steps. Just big enough to twist an ankle.






And those with keen eyes will notice I have the Blu-ray HDMI plugged into the auxiliary HDMI input jack on the front of the receiver and am successfully getting audio. So I'm guessing the HDMI input labeled for Blu-ray use somehow has it's audio set at something other than HDMI. I will be investigating that when I gather up enough courage to jump into the receiver's sub-menus.
