Answer 1

That speaker has a tweeter, a midrange and the sub cone on the unit. The tweeter carries the high signals. The midrange ( Medium sized cone at the top) carries the mid level sound signals and the sub of course carries the low booming signals that bring the bass. Unfortunately, if you are looking to get good Home theater sound, you will still need to purchase a powered subwoofer for your setup. The subs in the speakers are passive which means they draw their power from the receiver. Unless you have a good quality amplifier and equalizer, you won't get much sound from the sub on these speakers. Purchase an individual subwoofer that has its own on board amplifier and you will see significant change in your sound. A subwoofer of any major brand with a cone span of 12 to 14 inches should be sufficient.

Answer 2

Hi there. Well it says that it is a 3way speaker system with separate enclosures. Written on the side of the bass speaker it says that it is a Powered Super Woofer which means it has its own Amplifier to drive it.A Super Woofer usually goes down pretty low in frequencies so i think you will be alright .Try them out and see how they sound.I can't find out anything about them on the web,but i will keep trying. Is there any information about them on the back of the enclosures ?

Answer 3

this is not a sub woofer. it is not even a powered sub, which is obvious because there is no power cord or amp. this a what we call a full range, direct radiating passive speaker, with fancy verbiage to make it seem awesome. it once belonged to a bookshelf system you could pick up in a wal-mart. u need to buy a dedicated self-contained, powered sub woofer.
