Adding a little wub without all the weight?

[Jsmith7861]

As the title says, trying to add a little substance (see: wub) to my music without all the weight of a sub, box, and amp.

Any of you guys do it? Best to stick with just front speakers or am I over estimating how much all of it would weigh? I'm not looking for earth rattling bass, just like I said, I wanna feel the kick of the bass pedal a bit (listen to mostly rock, metal, and sometimes electronic dubstep stuffs).
