Dignity International Ltd

Oscar II, as an upgraded version of Orsa II, has a two-way floor-standing speaker and a 360-degree bass-reflex exhaust,
plus a computer-assisted point-source-style front panel tilt design, and a woofer to extend 400Hz 
The sense of low-frequency power up to 36Hz also increases the sensitivity of the speaker to 90dB, making it easier to
match various crystal or vacuum tube power amplifiers!
