I remember MDF was the choice back then for that reason. And yes- It's heavy. A full sheet is a little more than I can or want to carry, I'd need help. lol. Did you use that for the speakers too ?

I'm not BigmouthinDC but, yes the speakers are mdf. They are a kit from the DIY Sound Group.

My approach to buying sheets of MDF (49x97 inches) if to have them cut it into manageable size pieces at the store. In this case I had them rip a 17 1/2 inch piece off of each full sheet then I cleaned it up for the final 17 inch columns on-site. In the case of the Bacon Race we actually had them rip all the 10 inch pieces for the soffits at the store.

Tom, the front baffles were 3/4 MDF. The boxes were 1/2 inch Baltic Birch. At the dimensions of those speakers Plywood is OK, DIY Sound Group uses MDF for their sub-woofer boxes.

Oh, nice. I should have looked at the build pics again. I actually like BB better than MDF but, it's expensive.

it is hard to believe that DIYsoundgroup sells the CNC perfectly cut cabinets for $25 shipping included.

The entire cabinet ? Or just the face ?

What is it made from ?

OK- I never saw the link for $25. Thanks.

It seems like I could barely build a cabinet myself for that cost. Dragging out the table saw, buying glue, screws, etc... seems futile to do yourself almost. Even though I kind of want to do it eek.gif

You think MDF home built cabinet would make and difference versus the $25 they sell ? Better? What did you do ?

Isn't a sheet of MDF expensive these days ?

I built my own Econowave speakers and i can tell you this much if i knew about these flat packs then i would of bought them in a second. MDF a full sheet i think is close to 40$, it weighs a ton, the smell when cutting it is awful, the dust even if you have a shop vac attached it still makes a huge mess
don't forget you will need to invest in Jasper jig for cutting nice speaker cut outs there is another 40$ and hopefully it is compatible with your router assuming you already have one. The time and cost savings with flat packs is a no brain er to me.

Yeah. That is what it seems. I've built plenty of MDF sub boxes before and I own all the tools. The kit appears to come with CNC machine cut fronts. So making the box might be easy. I'm just wondering if it's worth it ???

Perhaps if I was doing all 11 speakers at once for 11.2 the savings might add up to take a full saturday if my time cutting and gluing and screwing. But for a pair.. I'd spend $50 in a split second to save the time.

a 2' x 4' x 3/4" MDF from home depot is 12 bucks which would make one box so it's only a 2x markup which is a pretty good deal unless you're making bulk boxes.

If you're just making like 1 or 2 boxes it's definitely worth it just to not have to get out the saw and stuff.

i think your math is incorrect your not getting six sides from one piece of 2x4 so not sure how you would even come close to getting 3 boxes

it will take two sheets minimum per box so that is 24$ ... so 25$ fully cut and ready to assemble is a very good deal i think smile.gif

There is a section of the forum talking about DIY speakers and a thread about the DIY sound group flat packs. Lets focus on finishing this theater.

I hope that's a good wow!

And I mean a damned-good WOW !!
post #380 of 801
I think the Wow! is more along the lines of great transformation of the space from basement to elegant theater. Looks very good. Soffit treatment using the beam to delineate the riser from the main floor seating looks like you set out to define two separate spaces, not like you were working around the beam. The design draws the eye to the screen and makes the main seating position a bit more intimate. Very nice look.

Really nice finishing details on that trim and paneling. How deep are the columns?
post #382 of 801
I love it !! progress looks amazing. !! Nice work !!

Did you use MDF as the back board ?



I'd imagine it's easier to paint and less sanding ?? Was that the reason ?
post #383 of 801
Wooooow! Simply beautiful! smile.gif

The columns are 10 3/4 inch deep because the speakers are 9 1/2 deep.
We did not use MDF on the walls just molding.
Fabric panels yet to be installed on top, dark brown surrounded by frames painted the cream color.
post #385 of 801

LOVE the colors!  An amazing transformation.  I didn't see this coming.

post #386 of 801
Nice job! I like the columns on each side of the screen wall. How much black area from the left or right screen viewing area to the column is there?

The upright is 3 1/2 inches wide, the 3 1/2 inch wide screen frame outer edge will land in the middle of the upright. It will be blacked out from there to the side of the column.

Looks Great!!! can't wait to see the carpet go in and and all finishing touches
post #389 of 801
Thanks Guys, but I owe all the credit to Big and Bill... I showed Big a picture and asked him if he could do it and he told me Yes, I can make it happen. All of the pieces are coming together just like we planned.
