A (late) Statements Build.

[Curt C]

+1
The grey foam available here (hopefully, a similar product is available to you) is easily molded to fit the mid and ribbon flanges, and flattens down to nearly paper thickness, so there is no need to compensate for it in the flange rebates. The weatherstripping I use is about 3mm thick.

C

I had no problem forming it around the Tang Band mids. I think there are differing densities of the foam, but the one I used was a gray color open cell foam and was very flexible. Worked very well.

[AdelaaR]

Thanks for the insight guys ... must continue quest to find the right foam.

You speak about putting it on the ribbon flanges ... is this necessary too? The ribbons seem to have a sort of soft tissue backside so I thought that would suffice.

Personally, I felt the supplied gasket was good enough, but it certainly wouldn't hurt to use the foam as an added seal.

Me and my wife have the flu since this weekend.
Today I felt a little better and was bored so I decided to make a jig for the driver cutouts as this is an easy thing I could do while being ill.

This is my current working place located in what is destined to become our kitchen one day:

I love raw workspaces like that.

Are you doing the masonry work?

Speakers before Kitchen! I like your style! :P

Everything from the demolishing of the old house to the masonry, roof, electricity, gas, water, windows, doors, floors, ceilings, insulation, etc ... is being done by me, my wife and especially my wife's dad

[Txgrizzly]

i love the home made table saw!!! my grandfather had something like that!!

[AdelaaR]

Hehehe
We live under the insulated roof at the moment in a temporarily installed studio with a small kitchen made out of old scrap wood.
This is the reason why the actual place downstairs that should become the kitchen one day is available as a woodwork and cementmaking shop.

That's awesome. When I purchase a house, I plan on doing everything myself.

I worked in masonry for about 14 years. my grandfather had his masonry business, my father.....I wasn't allowed to follow in the footsteps.

[AdelaaR]

I hardly know how old it is but probably about the age of your grandfather.
It doesn't start by itself but has to be pulled by a cord to activate ... real vintage stuff

[AdelaaR]

Go for it joeybutts!

It gives one a special feeling to have build one's own house brick by brick.
I'm halfway now ... the building is mostly done and now comes the tedious finishing off bit by bit.
Try not to have a deadline though ... we're at it for 3 years already ... with the right state of mind it can be loads of fun

[Coconutout]

hehe I'm afraid that when the speakers are done, you're not gonna wanna do anything else but listen to music all day. I remember when I finished my statements, I quit my part time job and my apt became a huge mess for about a month or so. That's how revolutionary their sound was to me. Enjoy

[Jinjuku]

I am midway through my Statements build (boxes are cut and dry fit). I have a question about port placement:

What audible effect are we talking about if it is down vs rear vs front?

I also take it that I will need to drill holes in the mid tunnels to connect the mids. Is silicone RTV the best/adequate product to seal up the holes?

Port placement won't affect the sound as long as you keep it below the plane of the drivers. Lower is better.

Silicone is good...

[AdelaaR]

jinjuku, I am going for a low front port myself.
Not because it sounds better (which it shouldn't according to Curt & Jim) but out of personal aesthetic preference and my general need of always having to customize things (I own hardly anything that hasn't been customized )

In fact ... I've been undergoing a serious flu the last couple of days so I was sitting around the house with a fever being bored and drew a little sketch of my intended custom design.

Image not available

I have left out the base and spikes and lengthened the whole speaker keeping the same height. Then ... I have compensated this increase of the internal volume by adding a separate crossover compartment to the low back making sure almost exactly the same volume was attained.
The lowest cabinet brace will then be attached to the crossover compartment for extra rigidity.

[Jinjuku]

Some build picks

Here are some of my pics.... I went above and beyond for the sake of cabinet rigidity and resonance abatement.

[AdelaaR]

Very nice indeed ^^ what version is this?

[Jinjuku]

Original, I hopped on the 225's when they were 1/2 off (PE was getting rid of them) and the TB's were on sale for X-Mas so I saved a good ~40% off the drivers.

Did you have to dado out the mid tunnel out sides facing the tweeter for clearance?

[AdelaaR]

Well I haven't started the actual build yet and I do not understand what you mean by "dado out the mid tunnel sides facing the tweeter".

John Trial's build. I just don't know if this is a requirement or if he was simply being meticulous. I probably will for good measure.

[AdelaaR]

Is this done to make room for the tweeter?
Doesn't the tweeter fit in the original design then?

[AdelaaR]

I have just come to measure my fountek and aparently it is indeed very slightly larger than the space between the tunnels is supposed to be.
Strange.
Was this also the case in the originals, Jim, or did they change the drivers or something?

I went ahead free-hand with a 3/4" flush bit and router'd out the dados.

My thought exactly when I measured.

Yeah, you have to do this:



This clearance cut is about 1/4" deep. It doesn't need to be that deep, but it can't hurt (notice the heatsinks on the tweeters...they'll need some airflow to dissipate heat).

[AdelaaR]

Thx for the info guys

[AdelaaR]

Today I made an autocad drawing of my custom design with metric measurements for my own reference while making the speakers.

Image not available

As you can see the port is in the front and the crossover is in a separate compartment in the back.
The height is increased to retain the same overall height without the base and the internal volume is kept almost identical.
Lots of work but I'm very glad I got rid of the inches and can now use my own measurements

[AdelaaR]

Made some small changes and corrections and a cut list:

Now I just need some MDF

[Tavaftw]

Nice pictures.
What's your grill design? I try to find Jim's link but that link doesn't work anymore.

[AdelaaR]

I do not understand what you mean by "grill".
If you refer to some kind of thing to cover the drivers with I don't think anyone who made the statements has something like that.

I've got grills to cover my drivers, and the rear tunnels.

[AdelaaR]

O nice! I hadn't seen those pictures yet.
Personally I like the look of the drivers and especially the statements have nice looking drivers with the black and silver phase plugs and the ribbon.
I know it might be problematic with dust though but they will be located in a seperate studio so they should be fine.

I lightly dust my drivers every so often... not the ribbon. You really can't tell they are dusty until you remove some of it. Not an issue for me.

[AdelaaR]

Just bought some sealing tape, paint, primer, extra clamps, speaker cable, etc...
Also found a 19mm roundover routerbit ... yay ... extremely expensive stuff though ... I was desperate because I couldn't find a 19mm bit anywhere and so I ended up paying 66€ for it since it is a pro quality bit :$
I ordered pre-veneered MDF and that'll take a while to produce so still waiting on that piece of the puzzle.

Guys, I'm having a hard time finding the right foam to put in the tunnels.
Can anyone please point me in the right direction?

I'm not sure what you have available on your side of the pond but here in the US, 1" flat foam is carried in hobby stores, upholstery shops, etc. The key is to get foam that you can blow through for it to work in an audio application.

The companies that manufacture foam would be the 1st place to check.

So the 1" Parts Express self adhesive foam won't work ?:cry:

If it's foam that is recommended for audio applications, yes, it'll work fine. There are less expensive sources locally for me but the audio foam from PE is fine.

Try fabric/craft stores. I used 1" thick seat cushion foam (open cell)...very inexpensive.

[Tim L.]

I ended up buying mine at he local Wal-Mart in the crafts department. It is one inch open cell foam, but it only came in bright white. Being that it is only visible from the back, I chose not to try to color it.

It's the dampening foam that you line speaker cabinet walls with.

Sure, if it's 1" thick flat foam, that works...
