Hi!
This is my first visit to this forum, a guy from Minhembio.com - Mötesplatsen för hembio- och hifi-entusiaster told me to write here since there are lots of experienced people here.
Now to the thing. I want to build a speaker, not an ordinary box with a speaker in it. I want to build something that's unusual, but still simple. I am 15 years old and not used to woodworking at all, so it has to be something simple. Tools are no problem, my father has pretty much everything that should be needed.
I have been thinking of a http://homepage.mac.com/tlinespeakers/FH/download/SuzyChang0v9-NBVR-map.pdf but then this guy from minhembio.com told me about The Metronome
Both of them look really cool, but the price is almost too much.
This is the first time i am about to build a speaker, so it has to be very simple.

Well, One should run a complete section (web page) just for setting up comparison charts with all these nice design seen around here in DIY. That same one person (or plenty) should mount a table with different parameters such as :
1 graph : freq response \ overall sensitivity \ working type (ported, with radiator, open baffle, etc.
2 building complexity chart (like to 10)
3 esthetism chart (like in 2)
4 Personnal judgment chart
5 etc......
6 Overall score
(for each well known quality drivers)
As for a first build Rullknufs, I would stick to something easy (square angles), MDF \ Plywood construction, with a bullet proof result design so that you dont get dissapointed with your efforts vs results
Your first prosposal looks fine to me.

Yeah.
I am building a small desktop speaker at the moment. Building it in 15mm (i think) oak and it is going to be a Peerless 830986 in it. I've started building the boxes and i must say it isn't the very easiest thing i've done, it's a litte bit warped (right word?), but hope it's gonna solve itself when i am gluing them together. Byggtråd - 3" desktophögtalare - Minhembio forum
But the http://homepage.mac.com/tlinespeaker...9-NBVR-map.pdf looks pretty easy to build.
But, i've talked to this guy from Minhembio and i think i should build a cheaper speaker since it's the first time. Practice on cheap and simple things and move up to more difficult things when i got more skills.
Totalcost around 120-150$ or so.

I am 16 years of age, and I'll be the first to say - this forum is the right place to be.
I find the full range with bass driver route is a good one. I use a fairly cheap (£15) 3" full range speaker, with a pair of bass drivers for each side. The sound is very good, and the whole project cost me £150, so maybe 200 euros.
What kind of amplifier do you have?
If you want to build one, look at 41hz.com, because they sell very good amplifier kits, pretty cheap. I built the amp6B, which gives 15w per channel (enough for parties, with efficient speakers), because it's one of the easiest ones to build.

I have a Harman Kardon HK 3490 amplifier, enough for any speaker that i am going to build.
I'd like to stick to one speaker, i don't feel for making filters and all that stuff. And, i want to build something unusual but still simple. And it has to be pretty cheap.

Suzy Chang is a pretty logical step up from your current project. Using plywood should be more forgiving than using solid oak...
Suzy can use Fostex FE103 or FE107

Well I dont think dry non-resinous wood will straight itself up. When working with hardwood you need big driyed pieces that you must run in rectifyers (un planneur et une dégauchisseuse- french words). After that, and only after that you can start working with your parts knowing that you are 90° edges everywhere and flat.
That is why I'v suggested MDF as a start. You can then apply a laminated hardwood sheet after if you like.

Well, the speakers for Suzy Chang will cost me around 1500 swedish crones, around 170$ or so. And the material for the boxes will also cost pretty much, so it wont be as cheap as i would like it. Ofcourse i could wait a few months for more money but, it is expensive.
But, it seems to be a good speaker and so on. But which is best, FE103 or FE107? The price difference isn't very much.

Well, yes. The oak was hard to work with but i think it will solve itself either by glueing or sealing with something.
The Fostex FE107e was around 400 swedish crones cheaper on Europe-Audio than on Hi-Fi Kit. With VAT and shipping it should be atleast 300 crones cheaper. So Suzy Chang might be an option...

I've been thinking about this project. It seems like i will build The Metronome. It's an "easy" box to build, my father will help me. But, so for the speaker...
I think the Fostex wont fit me very well. As far as i know i wont be able to play louder than normal listening volume with it and it can be very hard to make it sound right and playing it in can take many hundred hours.
So, what other full-range speakers can i use in The Metronome? Something that costs maybe 30-40$ each?

I have built 2 pairs of Metronomes, both using Fostex drivers: FE108eSigma and F120A. I can recommend the design, but I caution that the build is a little harder than you might think, due to the angles of the sides. And if you want lots of bass or VERY loud sound levels, then you would be better off looking at two way speaker using a large woofer.
You can't just run the plywood through a table saw and get it right. I rough cut the side pieces slightly over sized, then clamped a straight edged guide to one piece and used a flush trim router to get it right. After making one of each (front/back and side) I used that piece as a template along with the router to get the other three pieces of each just right.
Then the top and bottom pieces need to have sloped edges to fit inside the tapering enclosure. A wood rasp and sand paper (and lots of time) were helpful for that.
Note that the dimensions given in the metronome tables (found through the link you provided) are for the INTERIOR! You need to make drawings using the thickness of your plywood in order to figure out the proper dimensions of the finished pieces. If you want a driver other than the ones in the tables, then about the only thing you can do is purchase MJK's MathCAD worksheets ( Quarter Wavelength Loudspeaker Design ) and calculate the dimensions for yourself. (Since I have used the MathCAD worksheets to figure out a cabinet for the F120A, I might be able to give you some tips there.) NB: to calculate a cabinet, you need to know the T/S parameters of your driver!
Most full range drivers will require at least a couple hundred hours of break-in. Not to worry! Just set up the speakers in a basement or spare bedroom and let them run 24/7 for a couple weeks.
And be sure to check out the threads here on Metronomes! There is a huge thread called The Metronome (IIRC) and a small one I started when I built the FE108eSig Mets, called My Metronome Experience.
Cheers, Jim
Thanks alot for a good answer!
My father, who has been a carpenter earlier in his life, will help me with the building process. We got tools and everything ready.
I am sorry, but i can't afford buying a program. I don't got much money at all, i'm just 15...
Breaking them in is no problem, i will let them have their time.
I will try to find the threads you are talking about, and see what i can find.
If you recommend any other drivers just say, but they can't cost more than 40-50$ each.
I'd like to have atleast a decent amount of bass and be able to play above average listening volume, but i guess most drivers can to that in The Metronome?

If you live in sweden why not contact EAD and make a simple 2 way design using their exotic jordan 50mm JR6 unit and a good inexpensive 8" bass driver ? They should be able to recommend crossover etc
You could potentially make a great pair of speakers for around 200-250 euros this way.

What is EAD? I am new to this world 😛
Actually, i'd prefer a full-range driver and some sort of horn-construction. I don't want to build an ordinary box, i want to build something not so usual but still simple. As The Metronome.

front loaded horn using the 50mm jordan with a high sensitivity bass driver in a reflex cabinet could be cool.

Not sure if i want to build that. I think i'll stick to The Metronome and (probably) a pair of CHR-70 (2010 Revision) | Markaudio
If not too late in the decision process, an even simpler and still very satisfying build worth consideration are those in the Microtower series
http://homepage.mac.com/tlinespeakers/FAL/downloads/microTower-maps-150909.pdf
so far, I've built 2 dual-driver versions: "conventional" bipole CHR70 and the Castle with paper cone EL70 - as shown in the plans pages, the former in dark red, the latter in Cinnamon Cherry.
