Query: good sound small package

I got this to use with ipod and a 7"LCD TV I have in the kitchen.It has good sound, but lacks a deep bass, as you would expect because of the size. The only thing bothersome is a noticable power hum when using it with the TV. This only happens when the JBL is connected to the AC adaptor, so I'm not sure if it is a TV or speaker problem. No problem when using battery power.
