Last thing you want in your beautiful theater is a rattling column like I had in my last theater due to not gluing.

Also I'm jealous of all the Room analyzations you got from BPape. Where's mine?

Ruben,

When I re-made my (4) side surround columns and made the (2) new front columns, I DID use lots of wood glue 2nd time around. That was something that I did forget about the 1st time (and glad I thought of it the 2nd time). They're all solid as a rock now! However, thanks for the tip.

As far as your room analysis from Bryan, all you need to do is ask (as I did and as Bryan stated above). He is very flexible to work with -- but I'm sure anyone that has worked with him in the past already knows that

I was just joking around. The graphs aren't going to do me any good, that's why I didn't ask for them. As long as bryan knows the #'s and tells me where to put the treatments then that's all I want to know. If I start getting graphs, I will start trying to figure out the software and get really side tracked and next thing you know I will be making some more changes

Love to give u a hand when time comes for veneering. I need some hand on experience. It looks like you're coming along very nicely.

Ruben,

I am with you on that. I am a very detailed oriented guy and want to know everything about everything when it comes how my HT is built and how it will perform. However, on the room absorbtion/RT60 time, I have handed that over to the expert (bpape) It's just one less thing to worry about -- because you know (probably more than me) that there are plenty of other things that need to be done

hvn4179,

Thanks for the offer. Honestly, I've done a lot of woodworking before but nothing of this scale -- so it's a learning experience for me too. Maybe I should hire Sandman's helper to give me some assistance since he's done such a great job

I'm being replaced?!!?!?!!?!

Better be careful or you'll get accused of another DIY scam

Yep, Im following Sandman's work also. He's an ultimate HT dyi warrior . Also, we have to use the room in 2nd floor and I can't phantom of carrying hundreds # of sand for the stage using the stair

There might be a weight issue with your subfloor anyway. I'd just stuff it tight with R19 insulation (like 2 layers in a 6" cavity). That should take care of any resonance issues
post #70 of 2998
Steve, Its looking awsome so far. I like the look your trying to acheive. Very nice.

I'm close to you and also beginning my own HT build. Let me know if you ever need a helping hand.

Mini-Update..

..
Yes, the Blue Tape now lives in my room. I was feeling a bit bummed on the room and needed a motivator. Putting the tape on the wall and seeing the big screen did the trick. I'm ready to get this baby done!

If you have not already noticed, I make pics of just about everything so I can "change my mind" on paper many times before the actual build. This is a shot of the Front Entertainment Center with the lower section framing exposed.

NOTE: I have to move a few wall lights -- they don't do much good behind the screen



Here are (2) top-down shots of the Front Entertainment center. Top pic is the recessed shadow boxed screen with R13 insulation behind it. The lower section will house my sub and center channel. Notice the 2" OC703 in the back and along the 15deg angled sides to help control bass under the screen. The top and front of the lower section will be covered with GOM fabric.

Steve,

You know they say once you get the blue tape up, all your progress will slow down to a snails pace! You should have waited to buy that blue tape until the last minute!

Looking good! Love the drawings... puts my "paint" skills to shame!

Making the pics has made it SO much easier to show the wife what I'm talking about. My wife is also a very visual person and most of the design decisions for the theater would have been impossible to make without the use of these pics. Getting my wife to sit down, look at the pics and make a decision is limited (because of her "MOM" schedule), so I want to make those meetings are short and to the point. I think I have "decision" meetings down to about 5 minutes now

I got you beat Bud in the primitive department. I got a pad of graph paper and a ruler and drew the plans out. They are absolutely horrific, but at least i know what they mean. I'm on a PC or server all day at work, I don't touch them at home, except to go on AVS. Keep up the good work swithy, I enjoy popping in and checking your progress. Looking very nice.

PS - My motivation - I ordered my projector, receiver, front speakers, amp, and DVD player in the last two days. How long do you think I will let them go homeless??? Not very...

That's why I used Black Tape

Yesterday was a good day. I took the day off to work on the HT and feel I made some good progress. I managed to finally get built the top and bottom skeletons of the Front Entertainment Center. Yldesyde/David came over to give me a hand. Thanks again David.


Click HERE to Enlarge Pic

Here is the pic of the finished product. It's actually (4) pieces resting against each other. The front columns will eventually have holes cut in them for speakers - but I plan to do that after they are veneered. The bottom section will have black-out Commando cloth on the top and GOM on the front. The top section will have the same black-out cloth on the bottom and maple on the front. If you have not already realized, I will have the screen set back a foot or so to create a dramatic shadow-box effect. The inside edges of each of the columns will have the blackout cloth (to reduce reflections from the screen and add to the shadow-box effect). I must make this entire thing in pieces since I'm building it in the garage and will need to move it all upstairs to the Media Room once complete. At that point, I'll affix them to the wall and each other with glue and screws.




Here is the pic of the lower section on the left side. I have a 15deg angle on each side to help keep bass from collecting in the corners. These things took some thinking (2 hours to be exact) to get right, but I am very happy with the final outcome.


...
Here is a rendering of the final product. The crown molding will angle out 22.5deg (angle not shown in this pic). The thin slivery lines are ½ metal inlays I plan to sink into the maple columns. The end result will look like the next pic.


Next I plan to tackle the custom speaker holes in the (2) side surround columns.

Very nice job Steve! It should very good when all done.

Thanks everyone for the kind words.

I'm actually making some minor changes to the room design. I'll have more info and some pics once I get the kinks worked out.
post #82 of 2998
Minor like adding karaoke, a planetarium, extending the room dimensions, an automated door like on Star Trek that slides into the wall? Enough teasing, tell us the scoop lol. Or maybe you are taking a note from Sandman's page and you are putting in a fish tank, but instead of in the wall, it will be in the ceiling so it will feel like you are watching a movie underwater. How cool would that be!!!

Ok, back to reality. What's changing buddy?

Hey Swithey,

This weekend I was thinking about your color choices of your theater. Have you considered that they may be a little too light for HT? I just ask because I had light colored walls in my last HT and The light of the Screen would reflect off the walls and distract me. That's why this time I went with the darker colors.

Okay, I finally got the pics completed to show you guys what I'm changing. It's a long story but WAF came into play here -- so that's all I'm going to say

In a nutshell, I decided to flip the room 180deg and put the screenwall against what was the rear wall. The main benefit to this is that 22" deep front columns that stuck out further visually that I had thought are not tamed to 6.5" deep. I can now utilize the rear false wall to house the front, center and sub. I think it will give the room a larger feel and make things look less massive. So, onto the V2 pics...


Top View V2



Rear Seated View V2 from the bar stools


This is something I planned to do behind the rear wall but now will be exposed inside the room. The top part is a barrel diffuser to scatter sound horizontally and vertically around the space. The horizontal slats/shelves in the middle of the barrel diffuser will be the part that works the vertical axis. These shelves will only stick out ½ in the center and grow to about 6 on the sides (because of the curved nature of the barrel). The lower section is a tuned bass trap to smooth out a specific lower frequency range (Range is TBD by bpape).

...
Left and Right sides of the room. I do plan to put panels over the (2) door on the right wall because one is a reflection point.


What needs to be done:
- Cut down existing front columns (depth wise)
- Cut down lower section below screen

Should be fun

I'll have some pics after the carnage.

Ruben,

Already handled My walls will be covered with a dark coffee brown GOM fabric. The speakers will be covered with a lighter wheat colored fabric (to blend in with the wood and the leather on the seating a bit). I could not use the wall fabric in front of the speakers because it is not as acoustically transparent as the one I selected. Below are my exact fabric choices:


Left to Right:
- GOM Anchorage 2335 (2016 Onyx): cover ceiling absorbers
- GOM Vertical Surface Solids 2402 (278 Camel): cover column mounted speakers
- GOM Anchorage 2335 (2083 Coffee Bean): cover all wall panels
- Natuzzi Montecarlo: leather selection for the Natuzzi chairs

I wish it was something that exciting. Oh well, onto making more saw dust
post #87 of 2998
"Minor" changes he says

Seriously - no big deal.

For a little clarification on the rear setup. The 'barrel' diffusor is what is known as a polycylindrical diffusor. There was some dissusion about these types of things in another thread with Terry and Ethan. This provides some good dispersion in the rear of the room and reaches down pretty far down. The shelves certainly won't provide nice smooth polar plots but they do help in the vertical dimension some to scatter things in the upper mids and highs when used in conjunction with the poly. (It also makes good WAF points...)

The one big advantage of flipping the room is that there is now a lot more flexibility in terms of sub selection and placement than there would have been the other way around.

OKay guys, now that I don't need to house the sub below the screen, I was able to make the lower section shorter. With this change, I have some options for a slightly different look. The screen will be shadow-boxed back 2-4 inches from the front. The top and bottom sections will be set back about 1" from the columns on each side. However, I'm having a hard decision figuring out the "new" look.

Which one(s) do you guys like best?? I'm also open to suggestions.

NOTE: I cannot use the dark brown GOM fabric (that I am using on the walls) in front of the speakers because it is not acoustically transparent enough for speakers. The fabric I've chosen for the speakers does not come in a dark brown color or I would have gone that direction.

Option #1


Option #2


Option #3


Option #4


Option #5


Option #6


Option #7
post #89 of 2998
Option 5 for me. One thing I noticed with my screenwall being all black now (paint and linacoustic only) is the picture really jumps out. I still get some distraction on the ceiling and sides (white unfinished drywall at this point), but that'll go away shortly.

Bud

I'd agree. The black background for the picture really sets it off nicely.
