That's the idea in a nutshell, but it's always in some maximum or minimum - so choosing the best options is the name of the game.

You understand that the y modes you've also posted are all treated equally by putting the subs behind the screen, yes? Influencing modal response in that dimension will need subs out in the room somewhere.

And the reason we both came up with 90.3Hz is that I used your dimensions. wink.gif

Yeah, I figured that was the case.. You entered the width from my drawing which gets you the "x" modes. I entered the rest which seems to indicate my money seats will basically suck at 20Hz.

Alas, I am wired for subs in the middle of the room (connection is in the middle of the step up to the last riser) biggrin.gif So I can add in that location, but maybe only some 10's.. But that will be a "wait and see" type of thing.

In other news.. just returned from HD with 3 sheets of 3/4 ply for the second F20 smile.gif

He could try both ways to see which better....

My concern with mouths down facing inward, is that they would function as a single sub with mouths that close and lose benefit of multiple subs.

Also puts both mouths very close to 1st order pressure minima for width. I would expect that to create a hole that is not "fixable" with EQ.

Its worth a shot both ways though testing dont cost nuttin bit the beer ya drink while doin it!

Could one stand upside down, so the ports don't line up? I don't know if that's the element that makes them function as a single sub, as you said, but I thought it might improve that situation, as well as change the vertical pattern.

Moving them around is possible, but it will be tough. I think what I am going to do is remove one of the supports for the bottom the screen, lay the F20 down, slide it behind the screen wall, then tip it up.

Regardless of in-or-out, would it be better to have one mouth up and one mouth down?

Got the sides and top/bottom cut for the second F20. Happened to track down 4 36" clamps I had (had.. as in like 5 or 6 years ago I left them with a friend).. So I will be picking those up before assembly.

Making some progress; started fabric!

Also got the doors hung:

Used ball bearing hinges on the entrance door (plain hinges on the closets):

The gasketed Zero thresholds also arrived:

And the pièce de résistance:

The fabric has begun! I have all of the frames made for the black fabric. That big one you see sitting on the floor is a binary diffuser (one of three). It will sit in front of the Safe'n'Sound which is spaced 1" off the back wall. I cleared out a room in the basement to work and have everything set up. I just need to steal a few minutes here and there to crank out the rest of the frames. Sure wish I had a nice new set of fabric scissors. I have some nice scissors, but apparently not nice enough.

I've had to ration my spare time between the theater and the rest of the house. With warm weather finally here there's the usual yard work.. and I decided to paint the upstairs where it has endured years of the kids' abuse.

Lookin' good, Tim! The fabric marks a real transition - I'm jealous. Your pictures actually remind me - I really like the look of your woodwork. That's why I'm quoting you here from two months ago - what was the black you used?

I don't have much to offer, but I'll second Fred's sentiment. Looking good! I'm anxious to see how it changes the look of the room with the panels up!
post #339 of 595

Looking great Tim.  Your room is really beginning to transform.  Do you feel like you have turned the corner and the end is in sight?  

 

Where did you source the hinges?  Are they wide throw hinges?

Hi Fred, I used General Finishes Black Undercoat for the color. It's a high-solids paint, but sprayed extremely well. It sands easily and leaves a nice smooth finish. It's especially nice on MDF and other porous substrates.

They are not wide throw hinges. They're all 4x4 hinges for 1-3/4" thick doors. I got them from ebay. With the advent of fabric I definitely feel a lot closer to the finish line. I still have to finish up the screen wall, so I have that lurking in the back of my mind. I'm pondering going to order the carpet this weekend.

I've been progressing, mostly doing fabric. Here's a shot of the back wall:

IMG_1694.JPG

Here's a full column:

IMG_1692.JPG


Half column:

IMG_1691.JPG


Inside one of the columns:

IMG_1688.JPG

I wrapped 3/8" plywood with fabric, then those panels are held in with panel retainer clips. That way if something gets ruined I can replace the panel pretty easily.



I would probably have carpet already, but I made the mistake of trying to deal with Lowes. After waiting a week for a measurement, a couple more days for Lowes to call me, then me having to call them to follow up and actually get a quote, I found that they were trying to bill me for 624sf to carpet a 345sf room.

Yes, I am aware of the carpet width vs room width so I know there is waste (about 25% on a patterned carpet), but this amounts to 80% waste. That's right, unroll that carpet I paid for and throw about half of it in the dumpster.

I reverse engineered the quote and found that they simply ordered enough carpet so they didn't have to seam it. By having one seam it could easily be reduced to 408sf. Then they bill me for padding a 624sf room.

Note that I was home when the measuring was done and not a word said. I can understand if he asked if I wanted no seams, definitely a better job if it were a high traffic area, but I don't think the installer is at liberty to make those decisions. IMHO they were just trying to save the labor and who cares if the customer has to pay a few hundred more.

I am going to try and get my $35 fee back since I didn't receive a competent measuring.

Done with Lowes.. Will go to the local carpet guy, like I should have in the first place.

Fabric is looking good!  Carpet is a big step, but sounds like a frustrating one too.  Check online for certified carpet installers.  Then you won't be stuck with the markup of the shops.  They will probably be able to order it for you at a discount as well.

post #343 of 595
Nice work Mr. Tim! I love the look of that full column.

Sorry to hear about your problems with Lowes. Those are the types of situations I use to not only correct the bill, but to work with the store manager (not the dept. manager) to get the total bill down in consideration for such a gross mistake that you, a non-carpet professional, had to catch, Not only would it have cost you a lot more money, but it burned your trust. The trust always seems to be restored a bit easier with a fat discount! wink.gif
post #344 of 595
I've been having problems with Lowe's too. I actually was considering going through them for a couple other repairs I need to get arranged - but you've reminded me that one stop shopping just means more middle men to mess it up. Confirms that I want to do my own carpet, hopefully.

Fabric is looking good. Keep it coming!

The truth of the matter is that it isn't Lowes per se; Lowes is guilty by association. The guys there have been good (except for the one that said he'd call back in "a few minutes" and never did, I had to call the next day and speak to somebody else).

I have a strange feeling that the installer makes commission per square foot or per dollar sold. There is no way they can "carpet your whole house" for $97. So shame on the installer for screwing Lowes customers.. but by the same token, he probably can't make money at Lowes' compensation rate, so there is probably some blame to be put on Lowes for cutting the installer's profit margin to the bone.

In other news, the screen material arrived:

I'm going the DIY route (hard to argue with <$100 for a 120" wide screen). Yep, that's a box full o' spandex. White and light gray milliskin. Extremely smooth, I am optimistic it will look great.

Thanks guys, I'm really happy with the way things turned out. All of the planning paid off; things pretty much fit together like a jigsaw puzzle. I had to break out the block plane here-and-there to get the final fit, but for the most part assembly was effortless.

For the black I used the DMD acoustical fabric from acoustimac. I haven't ordered the GOM yet, but comparing the 701 sample tot he DMD, I would say the DMD is a nicer fabric. I have no complaints about the appearance or workability.

I'm looking forward to seeing how your screen works out. Where did you get the spandex material from?

Nice progress on the columns and fabric as well!

If you decide to go with it I can give you the dimensions I worked with. I did look at the proportions of classical columns.. so there is a bit of reasoning behind them. I will warn that it adds a lot of extra work. I am totally happy with the results, but the amount of extra work to produce them does make me question whether I'd do it the same way again

I may get the screen done this weekend. Not sure, I have another F20 to build. I got the material from Spandex World, which is only about 2 hours from me. If you want to learn about spandex screens there is a good thread in the DIY Screens section of the Display Devices forum.

I am going to build a wood frame and use Screen Tite channel to secure the fabric.

Would you change the look completely, or just the way you built them?

Just the way I built them. I like the look and proportions a lot. The joinery and rabbeting added a while new dimension to the diffculty. Yes, it looks fantastic, but honestly it is so dark you can't see anything!

If I were to do it again I would probably cut MDF to form the columns. ie take a 24x30 piece of mdf and cut a hole in the middle to accept the fabric. But that's really just due to the very little amount of spare time I have and the expected short amount of time I will have to enjoy the work.

Thank you! Here's a picture that's a little better than the others:

DSC_0031.JPG


I've finished all the fabric for the columns. I had to order more panel retainers to keep the fabric panels in place and double roller catches to keep the top halves of the columns in place. The roller catches work really well (no rattles).

Fabric at the rear is done.

Started finishing up the screen wall. I picked up the screen tight from Lowes, so maybe I'll get a screen assembled tomorrow. I also spoke with the Lowes manager regarding my carpet estimate. The only useful thing I got out of him was that he would talk with "the install department". He said he could send a different company out, I said no thanks. Nice enough guy, but I didn't get the sense that he was terribly concerned.
