Erica Horn

ERICA HORN is a 2 ways horn loaded loudspeaker system fully designed, hand crafted, and manufactured in Italy with optimum design and finishing with very compact size in respect to the low end frequency response and efficiency. Features a phase reversal triple folded back horn loading (custom design). The design suits for a very simple in-house placement. The 17 cm  ( 6 ¾") woofer has been especially custom made by us for the ERICA Royal Device loudspeaker system. The woofer has a mean sensitivity of 96 dB together with very high velocity, dynamic response and an extremely extended low frequency response due to the woofer very low resonating frequency and back horn loading system. The new MIRANDA constant directivity HORN is a perfect complement to it. The horn is completely Royal Device custom design product that loads a soft dome SEAS tweeter. This is crossed at 7,5 KHz with a completely flat response without using a frontal phaser. The hi-cut of the horn makes the speaker a perfect balanced system avoiding any horn nasality. The choice of no crossover on the woofer together with a new frontal WF mechanical alignment (designed for the LAURA MKII) gives a perfect  matching to the HI-HORN  towards WF decay using a 24 dB slope HI-HORN filter in a phase coherent manner.  Woofer bandwidth rise up to 10 KHz @ - 6 dB, for a full audio band direct radiation with no "midrange horn compression nasality". The ERICA HORNS features all the implementations made into the cabinet of the LAURA MKII version to get the maximum equilibrium between frontal loading and back WF loading for indoor use and better S.E. amp matching.  All components used are first class as the new generation  Royal Device AudioCap PPFF custom made capacitors.

 
  • N. 1 - 17 cm ( 6 ¾") woofer with high quality low weight paper cone on aluminum die-casting with central phase mechanical filtering for no crossover implementation
  • Woofer type of loading: Reverse phased triple folded back horn (custom design).
  • Features the NEW Royal Device Constant directivity  MIRANDA HORN ( 10 cm) Fully Hand-crafted in Solid Wood.
  • Horn uses a ¾" soft dome SEAS tweeter without frontal phase alignment as driver.
