So this is my first post sorry if it is not the right place. I have just recently gotten the audio bug. I am in the early stages of trying to make the most out of the random odds and ends that I already own. I have been taking older beat up speakers and rebuilding them. Mostly just new enclosures and soldering heavier wire to the leads. I've had pretty good success so far.

So here is my question: I just opened up a seriously cheap pair of speakers and found two woofers and one tweeter. One of the woofers had no driver and was therefore not connected and basic just a show woofer. Is this normal? Is there any audio reason to do this or is it just to give the appearance of being a better speaker from the front view? Can I slap a random driver of reasonable size on the cone and call it good?

Alright that was more then one question. And most of you are shaking your head asking why bother. Well I have no budget and actually I just like to see what I can build out of free or nearly free parts.

Any input would be welcome thanks in advance.
