'Boxer-Style' Low Centre of Gravity Design
Unlike top-heavy, front/rear-designed speakers that vibrate and move out of
position at high volumes, the Sound Blaster Roar is designed to be remarkably
stable with its low centre of gravity.
The dual opposing radiators produces equivalent counter-forces, this symmetry of
force prevents the unit from moving during extreme driver excursions.
The top firing "active" driver which incidentally also moves the "most" is backed
by the base of the unit and by the surface on which the unit is resting. The rear
forces of the active driver are then distributed to the dual radiators. This three-
action" pisotonic approach provides a very stable platform for a bass module.
Conventional active/passive approach has the active driver firing is one direction
with passive drivers firing to the rear produces uneven forces. This together with
the "top-heavy" and small footprint design causes the speaker system to move.
On bass heavy or loud playback the product may tend to "move".
