Acapella Ion Tweeter TW 1S

About the Acapella Ion Tweeter TW 1S

The Acapella Ion Tweeter TW 1S employs ion-plasma technology to generate sound by ionizing air with an electrically charged plasma field modulated by the audio signal, eliminating the need for a physical diaphragm or moving parts. This results in a massless diaphragm with ultra-fast transient response and exceptionally transparent, detailed, and natural highs. The tweeter produces a smooth, airy treble with no harshness, preserving subtle textures and spatial cues in music. It features a quartz combustion chamber where a violet-tinged yellow plasma flame oscillates to create sound waves, coupled to the listener via a 6-inch brass horn. The unit includes its own power supply and class-A amplifier, with adjustable crossover frequency and tweeter level controls. It is known for its unique ability to reproduce high frequencies with remarkable clarity, speed, and realism, making it a milestone in high-frequency reproduction technology. Dimensions are approximately 150 x 300 x 260 mm, weight 15 kg, with a frequency response extending beyond 40 kHz. Sensitivity is 1.5 V / 0 dB, impedance 600 Ohms, and maximum sound pressure level around 110 dB at 1 meter for 1 ms bursts. The tweeter automatically ignites and shuts off based on signal presence, enhancing usability. It is
