About the Acapella Ion Tweeter TW 1S
The Acapella Ion Tweeter TW 1S is an active ionic-plasma tweeter that produces sound through a modulated ionized-gas discharge rather than a conventional moving diaphragm. Its virtually massless plasma source is intended to deliver exceptionally fast transient response and highly transparent high-frequency reproduction. The unit has a 600-ohm input impedance, 1.5 V sensitivity at 0 dB, a maximum sound-pressure level of 110 dB at 1 m for 1 ms, and a frequency range of approximately 5 kHz to above 50 kHz, depending on the adjustable crossover frequency. It includes an integrated power supply and measures approximately 150 × 300 × 260 mm (H × W × D) with a listed weight of 15 kg.
