Description
IWISTAO 1 Piece Premium Pneumatic Ultrahigh-Frequency Tweeter Super Air Motion Transformer for Hi-Fi Speaker Upgrades
Model No: WHFSC-SAMT01
Please note: This stereo requires two units, so please purchase 2 pcs.
This product is designed as a powerful upgrade weapon for improving the sound quality of older speakers. By introducing ultrahigh-frequency compensation, it dramatically transforms the listening experience of traditional loudspeakers, elevating them to the level of high-end systems valued at tens of thousands.
Unlike conventional ribbon or dome tweeters, this model employs a high-end Air Motion Transformer (AMT) ultra-tweeter, effectively solving the shortcomings of ordinary high-frequency drivers—such as sounding loud but lacking upper-frequency extension, limited soundstage, and dull spatial imaging. Although the human ear is less sensitive to ultrahigh frequencies, their sound pressure significantly enhances openness, airiness, and scale, making the music scene more vivid and expansive.
Voice coil 35x28 MM
Voice coil 72x28 MM

Features
1. CNC-Machined Full-Metal Integrated Structure
Built with a full-aluminum enclosure and a fully integrated metal driver housing.
The thick, rigid aluminum effectively suppresses resonances, diffraction losses, and unwanted energy absorption during sound propagation. This ensures pure, stable, and non-degrading ultrahigh-frequency reproduction.
2. Dual-Mode Ultrahigh-Frequency Compensation System
Features an exclusive design supporting Ultrahigh-Frequency Compensation Mode and Ribbon Tweeter Compensation Mode.
It can function as a dedicated ultra-tweeter or integrate seamlessly with full-range or subwoofer systems, achieving smooth, full-band coherence.
Powered by a premium AMT/ribbon driver, it provides both excellent high-frequency extension and high power handling, delivering high sensitivity and strong output.
3. Five-Level Professional Sensitivity & Frequency Response Adjustment
Equipped with five precisely calibrated tuning modes, tailored for different listening environments and system setups.The high-quality aluminum knob offers precise, smooth, and durable operation.
4. High-End Internal Wiring & Crossover Components
The interior uses full oxygen-free silver-plated audio wiring, paired with crystal-clear gold-plated binding posts and premium crossover capacitors.
This ensures low-loss, high-fidelity signal transmission throughout the system.
5. Imported High-Precision Kapton Diaphragm Driver
Features a high-grade imported Kapton professional diaphragm with exceptional rigidity and fast transient response.
The unit offers high sensitivity, effortless drive capability, and compatibility with a wide range of high-end speaker systems. It outperforms traditional tweeters and ordinary super tweeters, delivering clear advantages in detail, dynamics, and imaging.
