Diana

Diana is a 30 liters bookshelf frontal load bass reflex / solid wood horn loudspeaker system fully designed, hand crafted and manufactured in Italy by Aliante s.r.l. with optimum design and finishing. The horn is a Royal Device product completely designed to reproduce full 2 – 20 KHz bandwidth at more than 100 dB efficiency together with a completely flat response without using any ogiva or phase alignment on the soft dome ¾" SEAS tweeter. The 8.5" woofer is another Royal Device product and has been specially custom designed for the Laura and Diana Royal Device loudspeaker systems. It delivers 97 db efficiency together with high velocity and dynamic response. The speaker implements no crossover on the woofer. The choice avoids different time delays between fundamentals and harmonics into the band of main energy content (up to 3 Khz) during complex music signals, reproducing music programs as real as the source is. To obtain the maximum results also the horn is crossed to the woofer using less than first order crossover network with a progressive 6 to 4 dB/octave slope. The components used are first class as the new generation Aliante AudioCap PPFF custom made capacitors used for the horn progressive filter.
