SD1.1-A for the Swans acclaimed SD1.1 new. Swans Home Theater Series is one unit. Germany’stop natural fiber using original spherical diaphragm vibration components, designed by the American engineers Swans, Swans in maintaining the original resonant frequency band energy SD1.1 suppression technology based on the substantial increase in the capacity of extended power tweeter unit high bandwidth, linear sound pressure to increase unit output range, which greatly improved the unit distortion in the high-power input, when the sound pressure output up to 96dB, total harmonic distortion at 2.5kHz above all less than 1%. Finite element simulation of high-strength die-cast aluminum panels, the appearance is very beautiful, low-distortion symmetrical magnetic circuit design, quality clean, round, maintaining the original flavor of the D series.
Especially for one-third of the treble frequency system.
Recommended crossover frequency> 2kHz crossover with 12dB ~ 24dB/oct.
