Need some advices for my DIY Project!

[Stygmata]

Hello Guys,
To introduce myself a little, i'm a physic student and a junior audiophile! ;d
I used to listen to music from headphones (have the Akg k-701 amped with little dot mk3 and Grado sr60i).
But now I'm searching for good quality loudspeaker at low prices and I saw some Do It Yourself kits like this one:
Kit haut parleur 3 voies 150 watts 8 ohms DIY 150/3
I also saw quite cheap amps like:
THE T.AMP S-100 - Cyberstore International Français

What about such stuff? Is it worth it?
I hope I'm not bothering you, if you have somes advices don't hesitate!
Any help is welcome ^^

Hi Stygmata, welcome to the forum, a kit is a good way to go, whether that one is good value for money I can't say (can't read French very well, & the site doesn't give brand names or parameters/graphs). What's your budget?
Have a look here for some good quality designs: Zaph|Audio
I'm sure someone from your neck of the woods will be able to recommend the best value drivers available locally to you.

I'd personally suggest going with Ye Olde Gainclone. There's lots of variants, but they're all quite simple to build, and perform very nicely. They're quite cheap, too.

That speaker kit doesn't look too impressive - the drivers appear to be pretty rubbish. For that kind of budget, you'd likely be very happy with the Modula MT - you can get all the parts at europe-audio.com.

For 200€ you can buy a complete loudspeaker.
DIY is not always necessary.

possible diy motivations:
1. do what can not buy.
2. do what is impossible to buy for this money.
3. love for sawing, soldering and lacquering by yourself...

Good quality &low price
If you are a Physics student ,you can study the mechanic of the driver itself ,and how all the parts are studied and assembled to achieve the double suspension+membrane+EMF*magnet oscillation .
Same for an amplifier ,from RCA cinch input to the power binding posts outputs.
This a good quality study for low price
For 130 € you can think of buying one woofer or one good tweeter ,that may
follow you for many years (reliability ).I saw also that crossovers are very expensive ,just for some meter of thin copper wire and some aluminium wrapped foil

[Stygmata]

Oh god! Thanks for all answers! ^^
So my budget is 400€ for one loudspeaker and amplifier which could drive two of those speakers :d

For 200€ you can buy a complete loudspeaker.
DIY is not always necessary.

I know that there're some good loudspeaker but my aim are:
-Get the best audio quality as cheap as possible
-Make as much as possible by myself to learn how it works
-Enjoy building my own loudspeaker (wood parts)

So I'm just searching to build 2 or 3 ways speaker with crossover filters in sealed enclosure with inside insulation and buy separate amplifiers.

This would be the next step with bass reflex enclosure! ^^

I saw that the DIY Gainclone amps are very very good for the price, could someone tell me where I could get one? ^^
Would you go on 2 or 3 way and what would you choose for 200-250€ speakers?

Thanks all for the help! ^^

Audio quality comes at a price like a lot of things in real life, like good wine for example .

yes, DIY could take a lot of years, I will be happy to read you in the next years . Note a low cost loudspeaker can be tweak.

spm-303 Qts : 0,25 in sealed enclosure Vb~Vas
bl > 20 for 70euro?
altavoz enigmatica..
may be spec is wrong..

[T101]

Everything looks alright if this is your budget, you actually get all the parts needed...

Only the crossover looks too nasty and is too expensive! 37 Euro is just a few euro short of what I spent for total capacitance (of many caps) near 600-700 mf, a pocket full of resistances - say 50 or 100... and say 4-6-8 inductances "custom" wound... - total inductance say... 10-15 mh...

Go for it!

The characteristics of the bass driver don't look too bad... with that QTS it will handle big tuning ports for the bass reflex or even a horn loading... 30 hz is fair enough for resonance...

But now as i think, you can buy only the bass, get Eminence midrange and whatever dome tweeter if it is not piezo...
