Nagota swan d-101

Does anybody have a decent set of plans for the SWAN D101.All that i have found are a hand drawn cut sheet in cm and no assembly plans. I plan on using the fostex 108es thanks

Have you looked here?

simple, all straight cuts.

Thank you for your reply's . I had been to this website but did not realize that the new drawings opened to a different file . Now i have one more question before i can begin . I have not been able to find the dimension for the thickness of material Mr Nagaoka used in his build .I have attached photo of my first DIY speaker the Harvey BVR . Many thanks to Scott Lindgren for his design.

the links on: http://homepage3.nifty.com/spida/eng-page7.htm &
http://homepage3.nifty.com/spida/eng-page9-1-3.htm
say: 15mm thick 910×1820mm plywood is half [two sheets and]-used.
from home page:
http://homepage3.nifty.com/spida/framepage eng-9.htm

But I used 5 x 5 x 3/4" baltic birch, & had to adjust so internal dimensions stayed the same...
Came out very stiff, doesn't vibrate at all, may have been overkill?

Did you just add 3mm to all the dimensions and build entire cabinet out of 3/4 ply
Do you have any build photos

 

[serenechaos]

not exactally...
mine are the super swans; dimensions are slightly different anyway because it's for 108es-II drivers.
but yes, I modified it so the inside dimensions remained the same--area/length/volume.
It took a little while to figure out...
No, didn't take pictures of anything; didn't even have a camera...

lotsa build photos in those links tho, even animation of how it goes together.

Guess i will have to find some 15mm ply in my area, and buy a metric ruler .Calculations are not my stong point. Give me a plan and i can build it .This should be a challange .the only link that opens is the SPI sound plaza and i cant find any videos.thanks again and i will stop pestering you .

SWAN build

Here is a photo of a mock-up i made from 1/4 " luan and hot glue tonight do the baffles looK like they are installed correctly thanks
BEN,

 

[serenechaos]

looks right.
looks like a good idea too, for building something questionable...
have to remember that one!

are you going to put a driver in it?
just wondering what it would sound like; being that thin & resonate?
would it have many different "pitches" resonating, (from dias) or just lengths, or what?
interesting...

 

[Andrewbee]

Nice mock-up. Cardboard works well if all you want is to see size and sound path.

The Swan plan has all the parts numbered and in sequence, as long as you follow the pictures and sequence it should be okay.

Swan update

Turning 3/4" to 5/8". Here is the result of not being able to find 5/8" ply locally. If i can figure out how to post multiple images i will show build progress

 

[serenechaos]

whut?
or i should say why???
3/4 is more rigid than thinner...
easier to just space it out a little...
5/8 is closer to 16mm...
but "close enough for goverment work," as they say @ work (in the plutonium facility @ los alamos national lab...)

To answer your question . I do not plan on installing a driver in mock-up but i will save it so that i can show people how the speaker works.

Has anyone out there in DIY world ever built the Swan ,i would be interested on there thoughts of sound quality. Currently have a pair of Harvey BYR that i built and a pair of Ed Schillings Hornshoppe Horns Powered by FI X-2A3 tube amp 3.5 watts

Plans call for 15mm if i went with 3/4 i was concerned that it would change internal volume, if you dont think there is not enough differnce to worry about it would save me alot of work because i still have to cut wood for 2nd speaker

 

[serenechaos]

Lots of people have built them.
I really like mine, they're my wife's favorite speakers, and usually end up being what gets listened to most when audio friends are over.
3.5 watts is usually enough, good enough @ moderate volume in small room for sure, I've used them w/ 2A3.
Sound real good right now playing the bluze w/ a little EL84 SET.

Not trying to be down, was just wondering why on the planing thing. Looked like a lot of work...
Built mine out of 3/4, but changed dimensions so internal area/volume stayed the same.
I sure wouldn't make one one side one way & the other side the other way tho...

I figured running a board through a planer was easier than trying to figure out the math, not my strong point. You would be surprized how easy it is to place a pieace of wood in a planer and my dog loves the fresh bedding .though i have been told that thicker is better

 

[babgrip]

Sawn

just did the math using the mock-up photo that i posted ,pretty simple adjustment.guess thats why you work in a plutonium facility and i work in the film industry.But my dog really does like the bedding,so he says but than again maybe he does not want to hurt my feelings

gonna try to post that link with the animation again, it didn't work from the lab for some reason.
