Focal arms its Utopia Be components with their Crossblock, a formidable crossover network that offers a staggering amount of control. The two woofer knobs give you a choice of 10 low-pass frequency settings and 8 different crossover slopes; the tweeter knobs let you select from 7 high-pass frequencies and 8 level selections. In total, the Crossblock gives you 80 woofer settings and 56 tweeter settings so you can tune this magnificent system to perfection in your vehicle. Focal developed the heavy-duty, hand-rolled coils and capacitors that are essential to this crossover's high efficiency and low distortion.
