The Opal Monitor bookshelf speakers have a two-way design based on the PSC 18.8 CS/M low-frequency driver. The low-frequency driver has been adapted to work in a smaller enclosure by changing the sensitivity of the suspensions. In the middle frequencies, the paper membrane provides an accurate warmer sound. A 25 mm tweeter with a silk dome is installed in the upper part of the range, which, due to its compact size, allowed the acoustic components to be positioned closer to each other.
The advanced crossover network in the Diamond Monitor 18 MKII was built using only linear elements such as air coils and polypropylene capacitors, which contributes to improved sound clarity.
Jasper Monitor 18 is a two—way system. Low and medium frequencies were "shouldered" by the 18-cm 4531G01 "Revelator" driver. The tweeter has a D2608 aperture weighing 0.18 kg. The speaker power is 180 watts with a sensitivity of 88 dB. According to the developers, the new system is quite enough to fill a 30 m2 room with high-quality sound.
