Building your own subwoofer

[jhuffy886 10+ year member]

Is it a good idea to build a pair of 12'' or perhaps 15'' subwoofer having never done it before?

I think this would be very interesting to do, I think it will possibly be cheaper, and I can buy pieces one at a time so as to not stretch my fiscal being...

I did it, but I read and learned for MONTHS. There is a lot you need to find out. Don't attempt it until you fully understand why you're doing each step. It won't be cheaper if you aren't sure of what parts you need or you don't have clamps, know how to shim it, etc. It could be quite expensive unless you have perfect execution.

There are things nobody is going to help you on either, such as exactly how to far the coil should sit in the gap. You didn't design the motor so you don't really know unless you have LOTS of experience, but you'll need to know this when gluing the spider to the former.

You could just get a drop-in recone assuming you're using the motor and basket from a particular manufacturer. They will know the perfect diameter coil, as well as spider landing and go ahead and glue it all up for you and solder the leads.

All you would do then is shim it, glue it, clamp it, remove the shims and then glue down the dustcap.

if you have never before but have a idea it still wont be what it could. by the time you get it rite it will cost you more in the end. if you have money to burn and want to try go ahead, thinkin it cheaper its not. make sure to beable to rebuild when the glue joints comeapart...

Thanks for the encouragement guys! aha just kidding

Thanks for the info, maybe I'll look into later on in life or as a side project; it would be a neat thing to get good at

On the surface it looks like a simple task, buy some cone, spiders, coil, motor and basket and slap it together, simple right ?

Not really. You have to make sure your coil is going to sit in the gap right, you have to figure out how you want the specs to be and get the right parts, cone weight can effect fs, there is sooooo much.

If you really want to learn, go over to the fixmyspeaker.com forums and pay attention over there. There are tons of people building subs on that forum and a lot of information floating around.

For the price of parts for your average joe, and the price to buy a motor.. you are better off just buying a used sub.. especially if you are a newb..
