[kartheek.cvs]

hello guys, i love watching and listening to movies and music. I have decided to buy a 2.1 home theater speakers with a medium budget. But later dropped because i am currently owning lenovo 2.0 speakers which came with the pc. They a pretty decent speakers with good quality output sound. I dont want to throw away these speakers in order to buy a new 2.1 home theater speakers.
My lenovo 2.0 speakers come with a 3.5mm jack as you all commonly know.
My wish is to experience music with rich bass. And my question is can i connect a separate subwoofer with my 2.0 speakers? Is subwoofer sold separately? How to connect? What specifications do i see in order to get good bass and how much the subwoofer costs?
please help me friends

It wouldn't be easy. You'd probably have to do some wire splicing to add the subwoofer in. You're better off just buying a decent 2.1 system.

Many Computer Sound Cards have a port on them for a Subwoofer

You need to buy a Powered Sub Woofer to plug into that port.

Use Google to find a Subwoofer to buy.
