I have a cheap $65 pair of altec lansing speakers, which are fine for now, becuase I dont have any money whatsover, but, it seems like the seem between the front of the box and the rest of it, so when I turn the bass up, it starts to sound pretty bad. If I put a brick ontop to close the seal it sounds pretty decent. What can I do instead of this. Is there any way to seal it easily or something like that. Thanks
