I want one Icon_smile

Can anyone shed some light on the performance of the passive radiators? How much of a difference do they actually make - or are they a marketing gimmick? I can't see how they can do all that much without a sealed cabinet (although I guess if the radio was up against a wall then higher volumes are going to have some effect using the wall as a pseudo-back-panel.

There are no personal problems that can't be overcome with the liberal application of high explosives
