The A200 horn loaded tweeter is a true ribbon tweeter. It inherits the mechanism of the tweeter in our flagship 7001i near field monitor, but with an added phase correction device which greatly improves frequency response and increases sound dispersion.
A 65mm length and 0.12mm thick aluminum ribbon is placed between the two large neodymium magnets. Electric current feeds through the ribbon so that it functions like a coil in a conventional loudspeaker. At the same time, the ribbon also acts like a diaphragm as it moves air. The combination of these two functions gives the ribbon tweeter high efficiency and great transient response without delay.
The A200 ribbon tweeter has a very low resistance of about 0.2 Ohm and it works with a transformer. The primary coil of the transformer connects to the amplifier; the secondary coil connects to the ribbon and it is wound of very thick and flat copper wire. The low resistance brings more current through the ribbon thus rise the SPL of high frequency, which leads to wide frequency response.
We construct the A200 tweeter with the highest quality aluminum ribbon, strong Neodymium-Rare Earth magnets material coupled with an appropriate transformer to give it high sensitivity, superb transient response, extended frequency range and ultra high definition.
The unique shape and size of the horn on the A200 tweeter was designed from precision calculation and simulation. Connecting the ribbon tweeter to a horn helps the sound generated by ribbon better coupled to the air. It further increased efficiency, power handling, frequency response and dispersion.
A wide frequency range and good transient response is vital for the reproduction of the dynamics of music such as what you hear in the musical density of symphonic music or jazz ensembles.
The horn loaded ribbon tweeter of A200 offers just the right features: high sensitivity, good transient response, wide frequency band, high resolution. You can now hear every nuance in the music, and enjoy it to the fullest extend. Attached thumbnail(s)
