Sorry I feel like an idiot asking this, but hey, I don't know what I don't know.
I have a microphone and some speakers and some box like things that you can attach speakers to (pictures here), and I want that whatever I say in the microphone should come out of the speakers loudly.
I think out of the two box like things I have that connect speakers to them, one of them is called a woofer and I think it's purpose is to equalize and also amplify sound but I can't be sure. The other one of the boxes seems like a useless thing that you just connect speakers to. It's just so you can connect speakers to it and channelize whatever sound you want into the speakers.
Well, I used to use one of these box like things, the woofer (Videocon brand) with my television set and DVD player. The other one is a Phillips make.
Before you begin to wonder why I bought these things if I know so little about using them, I just dug all these things out from my basement. They'd been lying there for years now. I got them free with some other stuff I bought at different times.
