Computer Subwoofer?

post #1 of 15
Thread Starter 
Hey guys, my uncle just gave me a bostwick 12" subwoofer that a firend gave him 5 years ago. He says it works, I haven't tested it yet, but I want to use it with my computer and just use my two sattalite speakers from my 2.1 speaker set. Some questions though, how do I power the subwoofer and speakers? My sattelite speakers get their power from the subwoofer that came with the set, how do I power the speakers without using the subwoofer? Also, what type of setup would I have to rig up to be able to use the subwoofer with my computer? Also, the center cone in the subwoofer is pushed in, how do I pull it back out? Thanks guys hopefully you can help me get working for my computer! BTW I can solder well and I am not afraid to break out the iron when required!

Wow... That sounds like one busted mess.

Let's start with the easiest problem. The center part of the speaker being pushed in. Get a vaccum cleaner and use the hose attachment, turn it on and pop that sucker on the center. If the center is smaller than the hose try to find a smaller hose? Should be big enough. If you have a very powerful vaccum you should constrict the flow a bit so it doesnt just suck the whole thing in lol. I've done this lots of times and it's fairly safe.

Okay next hooking the sub to your computer. Do you have the 5.1/7.1 connectors on your sound card? Does it have seperate plugs for Front L/R, Rear L/R, Center&Sub or is it just L/R + Mic + LineOut ?

If the subwoofer doesn't have an amp (what is it like just a big speaker?) you'll need to get one. It would all depend on your amp on how you'd hook the other speakers up. This sounds like a subwoofer from a Stereo or something?

All in all I'd say go out get an AltecLansing 5.1 set for $40, I have one and it totally puts my roomates two 15" + 500W he bought for $150 to shame. The tiny 10" sub on the AltecLansing puts out like Matt Flanigans mom.

I will deff try the vaccum thing. Well I have an old, 20 years probly, amp. It is made by Akia and served me well, until my sub went out, also 20 years old, and now it sits in a corner. Another problem with it is, it get so darn hot that I don't want to leave it on all day, you guys think that I need to put a fan on it. I also see a huge alum heatsink on it, mabye that is an opportunity to replace thermal paste? Yes the subwoofer is one from a buddies of his's trucks, just a speaker with some speaker wire coming from it. What I think I will do is use my RCA adapter to a 3.5 to hook it up to the computer and just use the old cabnets that I have, replace the bad woofer with the new one and just go from there. Also is bostick a good company, I look at there website and it says high quality audio, so I'm not 100% sure it is a good one. Also, will running 2 different subs sound weird? Well I can't try it out now, because I am at my grandpa's house, but I am suppose to be leaving today so mabye I wll be able to try it out. Ohh yeah, I forgot to mention, while I need to restuff the cabnets, or just use the old stuff, and if so, where would I get the stuffinf material and how would I put it in?

Wow, hehe ok a do-it-yourself person. Right then.

You can get the fill "stuffing" at wal-mart in a pinch it's as good as stuff you get elsewhere. Two subs you say? Never tried it.

yeah, two subs. Where in wally world would I find the filler? Yeah, I would rather do it my self than pay, or buy it. Well the cabnets have 1 high, mid, and a low, in that order. I plan to put both beside me and I have no idea where I will put the amp. Hopefully I will be BOOMing soon! I will post back with pics when I get home, now I am at my aunt's!

Back in the arts 'n crafts section they should have polyfill for making pillows and such. Now you realize with the onboard sound you're only getting stereo and not true 2.1/5.1/7.1 unless you run seperate lines for each channel.

Yeah, the amp is so old that I knew that I wouldn't get true 2.1. Alright, I will look back there and get me some. Do you have any tuts for me on how to stuff the cabnet?

you could just disassemble your sub from your computer and transfer the components over to your new sub. you would have to build a box for ur new sub and might need a more powerful amp but the setup should be pretty easy and then u can still use your 2.1 setup i did this with a 10 inch sub and it works well no distortion.

That's what I'm using. It's great becuz it has plugs for 5.1 3.1 or 2.1 and a effects switch on the back to make 2.1 feel more surrounding. I picked it up at a computer store for $48.95 a few months back. You might find em somewhere still but I just saw Altec isn't making them anymore.

The tiny subwoofer on this thing makes my friend's two 15" 500W speakers sound like old time radio.

They have this also http://www.alteclansing.com/product_...asp?pID=VS3251 I dunno how good it is tho but usually AltecLansing will beat the pants off any over-priced Logitech crap speakers.

Haha, I have a set of 2.1 altec lansing speakers, what I am listening to now. The only problem is that the 3.5mm from the sattelite speakers to the sub is a little loose, so if you wiggle is you will get a crackling sound, other than that, these speakers are pretty good for my subpar onboard audio. Also, I need to know how to find the ohms rating for my sub that was given to me. I looked all over the thing, but I couldn't find it, I have a multimeter, anyway to test it with that? I can give serial number and all if required, thanks guys
