build a box for pioneer 6x8's ??

[bmosso3]

I bought 2 pairs of the pioneer ts-a6872r 3-way speakers, 40 watt rms/240 max.

here is some more info on them

I later bought some components for the front, so now i have an extra pair of 6x8's laying around. I'm thinking about building a sealed (or ported?) box for them to use in my room because i need speakers and i have these and i have free time...

So my question is, what dimentions should the box be? Would they sound good in a sealed or ported box? I know boxes are usually for subs, but i figured it would have almost the same effect on a 3-way speaker right? Thanks for any and all input.

Edit: I could build one box for each or one big box for both, whatever you guys think would work best.

Take a look at those, for ideas there all about the right size for what you'll need, but there 6x9 not 6x8, and i would not try to mess with ported, as sealed will give a smother bass note.

thanks for the site. so for a speaker this size need about .3 to .4 cubic feet of airspace?

They work out to about .2 the key is don't go insane, keep it about .2-.4 and you'll be fine, can your receiver/ amp handle a 4 Ohm load though or just 6-8 ohm? Cause if it can't handle them you'll burn out your receiver.
