We have produced a new Unity Audio Brochure, because big brother Boulder will be here soon. We distribute Unity Audio Black Rock for very good reasons besides just do more business (We never pick this route). Black Rock packs very high quality standard in a small bookshelf speaker. Active electronics by EAR designer Tim de Paravincini, good ELAC drivers from German and acoustician Kevin Van Green designed DuPont™ Corian® cabinet. It has defined itself as a honest tool on monitoring and high quality listening.
Boulder on the paper is definitely big brother of Black Rock. Active crossover 3-ways design. A pair of Boulder monitors include 8 independent EAR discrete Class A/B amplifiers, that means each tweeter, mid range and woofers are amplified by independent amplifier stages. The front panel DuPont™ Corian® has increased thickness to 30mm. I look forward to hear if it sounds as good.
