摘要
<p>The box has two woofers which operate opposite to one another. The acoustic pressure from the woofers pitches commonly against a sound diverting unit (7) between the woofers. The unit diverts the sound upwards and downwards. The sound of both woofers is guided above and below. The acoustic pressure is amplified by an acoustic unit (9) and a trapezoid (8). The rise of pressure occurs between a base plate (1) and a bevel (12), and between a cover plate (2) and the bevel.</p>
