That's what I'm getting at. They don't need one but benefit from one. If you haven't heard it with an amp, i dono if its fair to tell people they don't need one for sure. Ppl might get it hoping for ear rumbling bass but unamped, its more balanced sounding (still sounds good) . Add some power behind these and they rumble. Although thought the presentation was more 3d with an amp.
