homemade subwoofer

Please check out my new video at http://www.youtube.com/watch?v=u4IeUElN8oQ

the basket is made from hardboard (wood-based panel) and universal glue. it's very lightweight, but a bit flexy. there are two stacked magnets from two old loudspeakers. the voice coil: 0.45mm (25 awg), 58m length, 6cm diameter, 4 layers, apr. 75 turns per layer, 6 ohm DC resistance, don't know the impedance. wound on varnished paper cylinder. the cone is 8" and weighs about 120g. the speaker sensitivity is poor because on the same volume levels it doesn't perform as good as my 87db sensitivity subwoofer and it also distorts a bit. maximum one way excursion is about 2,5cm with the pontetiality for more. the suspension is from strips of elastic, the surround is made from tape and paper. power handling - i would say around 70-80 watts rms, because when i play it with a 110 watt amplifier the coil heats and smokes in about 30 secs.
design considerations: the basket should be stronger; there should be more room for excursion; obviously the surround should be made from something else but i couldn't figure out how; don't know how to increase heat dissipitation - the main factor for power handling; the cone and voice coil should be lighter for more sensitivity; i'm also building a ported box for the speaker - will upload video when done
please comment and rate :)

i don't get it... Where is the fixed magnet?

[svinec]

@Motherfuckersito just inside the coil of course :)

[svinec]

dude, i suggest you to try build a speaker yourself :) soon i'll upload a new tutorial, it will be more useful

there are no air-leaks! there is transparent tape on the surround.

there are two ferrite ring magnets from two old speakers. the magnets are not big at all

[iintro79]

@borismontoya136 rawr...

[borismontoya136]

@Skrillex911 No fucking shit that it sounds crappy dumbass... why would you even say that when you know he didnt use a box... Gtfo and listen to your gay ass skrillex shit + make it yourself if you think you can do it better.

[Skrillex911]

sound's like shit, and ill tell you why.... first off your "surrounds" on that thing suck, and 2nd thing is that you need a box for it, trust me just those two inprovements make a huge difference

[pchsnova6]

plug some korn into that puppy and watch it go!

@mrGovnoff nope, i just really like it, and want to try too reproduce one myself. I just dont know how too make the coil wire too 4 0hms. or any ohm for that matter. I was gunna use ur model as a starting point. Inless u can just tell me how too make a coil 1-2-3-4 ohms? what size wire? how long? how thick of wire? How wide do i wind it? so many things lol;

[mrGovnoff]

@duhweedman420 Yeah, I probably know why you need a copy of this subwoofer: you're just wanna replace the cone with your FleshLight, have I guessed right or wrong?

[linkinpark345123]

how did you make the electromagnet?
