I heard that system has more sound quality than the more popular Z-5500, probably due to the fact that passive radiators require more effort put into the design than just a normal ported box as far as the sub goes.
However, I'm more into custom designed speakers as you can make them proprietary to your application.
@1500Tb It's a subwoofer with no magnet, and no coil, so it's just a cone with the surround, and it works the same way a port does, by vibrating extra air : ).
Yeah, pretty much. I'm planning on removing my videos and starting from scratch. But now, I have no new footage (and no working camcorder) and I can't work on speakers at least until I meet someone who'll let me use their woodworking tools, because I live in an apartment now.
But yeah, I was going to add a speaker and make it a real passive radiator, but I abandoned the project not long after the video was posted.
dude...i took 2 4 inch subs, one started rattling so i figured what the hell? ripped the shitty one apart and made a passive radiator. damn shoe box was all i had and i couldnt get the powered one to force excursion :[
4 inch subs are never technically considered "subwoofers". They're considered mid-bass drivers because their size is just too small for use in a professional system as a sub. But computer speakers use them anyway...
Sorry about your subs though. Put the surviving one to good use and make it a midrange : ).
It's not really a passive radiator, it was a subwoofer driver without a basket, magnet, voice coil, ect. that I was going to build, but instead, now I have an actual subwoofer. But the subwoofer needs new surrounds.
Yeah, I was going to build a sub off of that with the driver actually attached to the box, but the surrounds were noisy.
I put an 8" subwoofer in and replaced it, but it needs new surrounds, but $20 for a foam ring is too much for my family. Unless I can get a surround for around $5, I won't be getting them anytime soon.
Passive radiators are generally used in a sealed enclosure to REPLACE the port. Don't expect this to sound any good... It would sound better if it were in a sealed box but then the air from the subwoofer would destroy the homemade surround on it. Nice box though. If you buy a surround for that passive radiator it might actually do alright.
I should retitle the video. It's not a passive radiator. It's an unfinished carboard driver. The port will be a port and the passive radiator is a driver with no basket, magnet, or voice coil, even though it was meant to be a full driver : ). Besides, where could I get a surround pre-made that would fit (I have never seen a surround with a 6.5" ID and 9" OD, let alone replacement surrounds)?
Hey dude, Theres a guy that can help you make a working subwoofer, He helped me it works and sounds good, His name is J07C24S88. Look him up, He gave me the dimensions, type of magnet,materials,and the9876543 is kinda right cuz i have the z-4 and theres no port cuz its a 8" passive radiator. Very good design and you keep up the good work duuuuud!
Funny you mentioned him. I've seen all his videos and we've been discussing all the details and he's pretty much already told me everything I need to know. I'm currently working on a 12" subwoofer, but I need to get the voice coil (I'm thinking about buying a premade one for a few dollars more than the wire), and after that I just need to cover my foam box with paper mache to strengthen it, the I need the magnet and voila! A working subwoofer!
Nope, money problems. What type of wire did you use? I haven't gotten a chance to experiment yet, but I think that thicker wire would be best. Look up Magnetwireusa-dot-com, and you should find some nice large roles of wire, most of them about 1000 to 3000 ft. spools, enough for multiple powerful subwoofers. I'm gonna show my mom the website in a few minutes : ). Also, what magnet did you use? The bigger the better!
Sorta yes and sorta no. That will be the real sub. I'm making a subwoofer from scratch, but I made the basket too big and it doesn't fit, and I can't re-do it, so I'll have to wait until I get another foam board.
Thank you for calling me smart : ). The passive radiator isn't going to be a passive radiator when I'm finished. I'm hoping for results like what J07C24S88 (the channel of the video this video responds to) got. The port will be a regular port, but I might want to redo it into a square or rectuangular port so it'll be easier to build. I'm hoping I could tune it to 20Hz or lower. The long and thinner the port, the deeper the frequency it's tuned to. I'm hoping that it'll be bangin' when it's done!
Hey I built one of these a while back but never put it on youtube. It was a 12" and I also made a 8" square one too.
You can get the magnet wire(voice coil) from RadioShack for $5.99. It come with 3 spools of enamel coated wire 40' of 22AWG, 75' of 26AWG, and 200' of 30AWG. It's easier to use the 26AWg wire because all 75 feet of it ends up being 3.6 ohms (4 ohms nominal).
Did you see my newest homemade sub? It have neo magnets an it sounds better and a lot louder.
Thanks (can I call you "J"?). Are you saying you get 40' 22AWG + 75' 26 AWG + 200' 30 AWG wire for $6?!?! And someone said it was expensive. Even if each roll is $6, that's way better price than what I thought. I have a receiver in my room, it puts out around 15 watts per channel on listening volume (I have two 28 year old Fisher 9"s with a 4" tweeter and 2.5" super-tweeter). If I connected a 4 ohm sub two a reciever that says "Warning: 8-16 ohms only" would the 4 ohm sub get fed around 8 ohms?
Yeah. I put my 4 ohm homemade sub my radio which said put no less than 6 ohms on it. when I turn it on the fan turned on and didn't know it had a fan in it. After that it made a pop noise and went into protection mode permanently.
My sub get ~25 watts I don't know if its max or rms it don't say but if your reciever says 8-16 ohms use 2 spools of 26AWG wire to get 8 ohms for nominal impedance if you measure it with an ohm meter it should be no less than 6.4 ohms it would be around 7.2 ohms with 2 spools. For best results make the voice coil the same height as the magnet(s) and place half of the voice coil half way through/over the magnet height.
Place the voice coil exaclty halfway above the magnet Also, where could I get an ohm meter? And does radioshack sell subwoofer magnets? BTW, I don't have an amp OR any subwoofer that I could use for parts. I won't use my reciever because (I'm not sure if it's true, but I heard electronics were crazy expensive back then) I heard that it originally sold for about $2,800 (JVC RX-307).
Should I just go ahead and use masking tape to build my sub? I don't have duct tape. It costs $8 at every place that sells it!!! And besides, I could always add a layer of duct tape if I ever get any.
AWG stands for guage. What's weird is the lower the number, the thicker the wire. But 30 AWG wire is too thin for a subwoofer coil, so I would recommend anywhere between 20 AWG and 26 AWG wire.
the Edifier s730 has two passive radiator and one aktiv. all three is 10''
