Making a Speaker

[Flik]

I just did a search on MX for another topic relating to this, but didn't find much.

Basically I want to make some speakers for a PA for vocal use. Mainly for experience value, but also maybe as some backups just incase my band gets to much for the other speakers :p

Is it as simple as picking the right speakers (is the proper name 'drivers'?), getting a crossover and a suitable amp?

I understand this can bridge onto loads of other stuff, so i really appreciate any facts you point out.

Cheers!

my mate made a speaker ill ask him were he found out how to do it?

:lol:

For a second when i read the title i thought you were going to wind your own coil, buy a magnet and then craft the cones yourself...


Acoustics do come into it, but you can either make them open backed (with a baffle 1/3 up the back) or make them closedback and fill it with something to absorb the bass reflex. If you do it either of these ways and don't worry about bass reflex tubes and all that shiz.

The more you spend on the driver, the higher quality the wood, the better sound. The more carefully you put it together, the longer it'll last.

That'd be nice dude, cheers :)

So I'm right in describing the actual erm, 'circle with the magnet and coil' as the driver then?

typically speaking, the amp is the complicated part. It's fairly easy to brag any old cone, mount it into an open backed enclosure, and just crank it up.

The results are fairly typical with this method, but at least you'll know the specs (they'll be most dependent on the cone in this configuration since you're not creating hemholtz/waveguide resonances). One suggestion though is to find a good spongy material to damp the interior of your cabinet, to smooth out frequency response. You'll lose output efficiency, but the overall sound will be more consistent across the audible freuqency spectrum.

For a good vocal speaker all you really need is a 12" or 15" raw speaker, horn, and a crossover. Check out Carvin (http://www.carvin.com/products/group.php?CID=RSPK)'s parts, just make shure you match up the wattage and impedence.

Cool guys, thanks a lot. You've helped more than you know!
