Aperion DST Dual Firing Air Motion Transformer Ribbon Super Tweeter Pair
With this DST Super Tweeter, you’ll be able to hear every detail of your music clearly and beautifully, making it feel like you’re enveloped in the sound!
You may be familiar with the popular Planar PST and Aluminum Ribbon Super Tweeters RST, but our APERION Dual AMT DST Super tweeter delivers quick dynamics and an ultra-clear high frequency transient response.The Dual Firing DST Super Tweeter can be suitably matched with any speaker whose sensitivity is between 96 dB and 87 dB.
The actual size of the driver is 3.19 x 1.34 inches (81mm x 34mm). The thickness of the Kapton is 12.5 μm, the Aluminum is 20 μm, with a total thickness of 44 μm. Sensitivity was tested using 2.83v @ 1 meter. The crossover design is Butterworth. Using FR4 PCB board, and Aperion custom capacitors. The internal cables are high purity copper to minimize resistance.
It is a single ribbon, with dual firing open baffle. The driving force of this transducer is evenly distributed over the entire vibrating element.
This is not an ordinary tweeter
Traditional tweeters produce sound by pushing air using a diaphragm. In contrast, the Air Motion Transformer (AMT) compresses and expels air through a folded diaphragm, functioning like an "air accelerator." Since the airflow speed greatly exceeds the diaphragm's movement, the AMT offers remarkable sensitivity, an impressive transient response, and extremely low distortion.
For many audiophiles, a high-quality AMT tweeter combines the finesse of a ribbon tweeter, the dynamic impact of a compression driver, and the clarity of an electrostatic speaker. After decades of development, the AMT has firmly established itself as one of the most renowned tweeter technologies in modern high-end loudspeakers and professional monitoring systems.
While a ribbon tweeter "pushes" air, the AMT "jets" it. This fundamental difference is why it can deliver such an extraordinary sense of speed and airiness.
Pre-Purchase Information
1. Super tweeters are designed to work alongside your existing speakers, not to completely replace a burnt main tweeter.
2. Keep in mind that a super tweeter's output volume is dependent on your hearing, so what some percieve and hear, you may not.
3. Aperion Audio Super Tweeters enhance the overall sound experience, it does not guarantee "perfect" high-frequency sound. Instead, it enhances the sense of spaciousness, and airyness, while compensating for the high-frequency limitations of your original speakers, resulting in a better listening experience overall.
4. In our experience as a rule of thumb, ensure that the sensitivity of the Super Tweeter is equal or higher than that of your existing speakers. For example, if your speakers have a sensitivity of 95dB, we would recommend our Super Tweeters with 96dB sensitivity to give as much wiggle room with fine-tuning the sound to your personal preference.
5. The key to using super tweeters lies in experimentation and enjoyment. Achieving the best sound for your particular setup requires time and adjustments, and we usually recommend people listen to, and adjust their Super Tweeters for around 20 Hours.
6. Listening experiences are highly personal; it's completely normal for some individuals to notice a massive difference while others may only notice a small or no difference at all.

Product Features
Take Your Sound to the Next Level
A super-tweeter speaker enhances your speaker system by improving the detail, energy, density, and texture of the high-frequency range. It also broadens the stereo soundstage, providing greater width and depth. This type of speaker is a fantastic addition for those whose audio systems lack vibrancy, clarity in high frequencies, expressiveness, or adequate high-frequency output.
Innovative Design
The DST Dual Firing AMT Super Tweeter, crafted by Aperion after extensive research and development, is a remarkable audio component designed to elevate your listening experience. This innovative tweeter projects sound in both forward and backward directions simultaneously, creating a more immersive soundstage that envelops the listener. By radiating sound from multiple angles, it enhances clarity and richness, resulting in a fuller and more dynamic auditory experience that truly brings music and sound effects to life.
High-end, classy, and sophisticated.
The Aperion DST boasts a sleek, contemporary design that exudes elegance and luxury. When you position it atop your speakers, it not only enhances the visual appeal of your audio setup but also elevates the entire ambiance, infusing the space with a sense of refinement and upscale sophistication. Its premium craftsmanship and stylish lines make it a stunning focal point in any room.
One-to-One Pairing
Each pair of Aperion Super Tweeters have been meticulously tested and carefully matched to ensure optimal performance and consistency. This rigorous process guarantees that every unit meets high standards of quality and sound fidelity, allowing you to enjoy an enhanced audio experience.
HiFi Music & Movis
Super tweeters can be paired with full-range bookshelf speakers, two-way bookshelf speakers, tower speakers, and home theater front or surround speakers; they are not limited to use with Hi-Fi music systems. You can also add super tweeters to a home theater system used for watching movies. Since many modern DVD and Blu-ray recordings capture frequencies well into the tens of thousands of Hertz, adding a super tweeter allows you to fully reproduce the audio effects and achieve the best possible listening experience.
Where should it be placed?
The optimal placement for a super tweeter speaker is on top of your loudspeaker, though positioning it immediately beside your speaker's tweeter is also an option. The primary goal is to achieve a "point source" effect, where the sound originates from a single, unified location. Additionally, because super tweeters have a faster response time, you may want to position the unit slightly farther back—while still keeping it vertically aligned with the high-frequency drivers—to ensure that the mid-range, bass, and high-frequency signals reach your ears simultaneously.
Also, just play around with the placement

Dual Air Motion Transformer Ribbon tweeter
Aperion's Dual Air Motion Transformer tweeter adds clarity, transient speed, and musical finesse to almost any loudspeaker. A natural fullness in the treble is exhibited; reminding us why we love high-end audio so much.
5-point Crossover + OFF
Select from 8, 10, 12, 14, or 16 kHz to adjust the Super Tweeter floor for optimal integration with your speaker system. When set to "OFF," the Super Tweeter will be inactive. The 8 kHz option offers the greatest overlap with your current tweeter, whereas the 16 kHz option provides minimal overlap, focusing on the higher end of the frequency spectrum. The crossover slope is set at 12 dB/octave.
Treble Adjust Knob
Too much of a good thing? Use the treble adjust to reduce the output of the Super Tweeter. Just turn the dial to adjust to your taste, down to -5dB.
Pairing the DST Super Tweeters with Your Speakers
Using the Theatrus T63S's as an example, and it's 91dB Sensitivity, to match this take a look at the chart on the left, where you can see the Crossover and Treble Adjust is set to 8k Hz and -5dB, giving you 91dB output Sensitivity, your other options include 10 kHz and -4dB, 12kHz and -3dB, 14 kHz and -2dB, or 16 kHz and -1dB, though we highly recommend you to try every setting and see what works best for your ears.
Easy Connection
Aperion Audio Super Tweeters are external devices that connect in parallel to the binding posts of your passive speakers—just ensure that you connect positive to positive and negative to negative. The key is to experiment; avoid listening too closely. Instead, assess the sound quality from your usual listening spot to find which setting delivers the most natural, balanced, and seamless integration. Once you pinpoint the crossover setting that appeals to you the most, you can keep it for long-term use.

FAQs
What's in the box?
The DST Dual Firing Air Motion Transformer Ribbon (AMT Ribbon) Super Tweeter comes with a QR-manual download card, and the two tweeters.
Can only dogs and cats hear it?
It is well known that the human hearing range is 20 Hz to 20 kHz; in reality, many older adults cannot even hear frequencies above 15 kHz. Since the human ear cannot perceive frequencies exceeding 20 kHz, why is there a need for "super-tweeters" that reach 40 kHz? Consequently, many people online claim that such sounds are audible only to cats and dogs.
This is a common misconception. When we design super-tweeters capable of reaching 40 kHz, the goal is not to enable you to hear 40 kHz itself, but rather to enhance the quality of the sound within the audible range (up to 20 kHz).
To take a simple example, suppose there are two tweeters:
A: Frequency response limit of 20 kHz
B: Frequency response limit of 40 kHz
If both are made to reproduce a 15 kHz sound:
A is already approaching its frequency response limit:
- The diaphragm begins to exhibit breakup (modal vibration)
- Phase distortion increases
- Distortion levels rise
B is operating at only half its capacity, so:
- Its sound is more linear
- Distortion is lower
- Transient response is better
It is akin to comparing two cars: one with an engine capable of 200 km/h and another of 400 km/h. When both are driven at 100 km/h, the latter operates with noticeably greater ease and composure.
Thus, the true value of the Aperion Audio super tweeter lies in:
✅ A higher diaphragm breakup point
✅ A more linear operating range
✅ Lower distortion
✅ Faster transient response
✅ Superior phase characteristics
✅ Greater dynamic headroom
In other words:
The pursuit of a 40 kHz range in Aperion super tweeters is not about extending the upper limit of human hearing; rather, it is about ensuring that music reproduction within the 20 kHz range sounds more authentic, natural, and effortless.
What is the purpose of the Aperion DST Dual Firing AMT Super Tweeter?
The Aperion DST Dual Firing AMT Super Tweeter is designed to enhance the high-frequency response of your audio system, extending the frequency range up to 40 kHz. This creates greater detail, airiness, and a more immersive soundstage for both music and movies.
What types of speakers can the DST Dual Firing AMT Super Tweeter Pair be used with?
The DST Super Tweeter can be matched with any passive loudspeaker whose sensitivity is between 85 dB and 96 dB. It works with bookshelf, tower, center channel, and surround speakers, adding clarity and imaging to a wide variety of audio setups.
How do I connect the DST Dual Firing AMT Super Tweeter to my speakers?
The DST Super Tweeter connects directly to your main speakers via their binding posts. Simply connect the super tweeter in parallel with your speaker's inputs; no separate amplifier connection is required. The 5-way binding posts support bare wire, banana plugs, spade connectors and more for easy installation.
Can I adjust the crossover frequency and output of the DST Dual Firing AMT Super Tweeter?
Yes, the DST features a 5-point crossover knob (8kHz, 10kHz, 12kHz, 14kHz, 16kHz, or off) and a treble adjust knob (0 to -5dB) for precise integration and level matching with your existing speakers, allowing you to tailor the sound to your preference and system needs.
What are the primary technical specifications of the DST Super Tweeter?
Key specifications include a frequency response of 8 kHz – 40 kHz, 4 Ohm impedance, 96 dB sensitivity, recommended power handling of 10-150 Watts, and a 12 dB/octave crossover slope. The enclosure is built from aluminum alloy for acoustic and aesthetic benefits.
