Our new Flagship Dual AMT Super tweeter delivers quick dynamics and an ultra-clear high frequency transient response, expanding the atmospheric sound stage like you've never heard before. The light, airy highs produced by our AMT super tweeter are incredibly smooth, providing an effect which transports you even further into the sonic abyss of your music and movies.
Tech FAQ - 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, in total thickness of 44 μm. Sensitivity was tested using 2.83v @ 1 meter. The crossover 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.
The AMT can be suitably matched with any speaker whose sensitivity is between 87-98 dB, so this higher SPL rating allows the Dual AMT to be matched with power hungry speakers. While we've received plenty of stunning feedback on the Dual AMT's predecessors, we had an AMT style design in mind from the start - after years of development, we are proud to announce the Dual Air Motion Super Tweeter.
Too much of a good thing? Use the treble adjust to reduce the output of the Super Tweeter. Just flip the switch and adjust to taste, up to -5 dB.
The Super Tweeter shares the same binding posts as the speaker you're pairing it with. It feeds off the power your main speaker is already receiving, so no need to connect directly to an amplifier.

Of the many ideas on how to build a loudspeaker transducer, the Air Motion Transformer is unique in its way of making the air move. In the course of the history of loudspeakers, many different transducer designs have been introduced. All of them feature piston-like diaphragms that move the air in a 1:1 ratio so that the diaphragm velocity equals the air velocity. Whether we talk about electrostatic and magneto-static speakers, ribbons, voice coil based dome and cone speakers or even a Blatthaller design – they all follow this particular design approach.
The Air Motion Transformer is an electromagnetic driver, as it is based on the Lorentz force that moves the air in the single folds.The diaphragm itself has an aluminum circuit printed on it (violet arrows) and is surrounded by a strong magnetic field. The graphics in and around the small circles show the motion of the individual foils producing a sinusodial waveform: from where it starts (black circle) through the positive (green circle) and negative (red circle) half-waves. The resulting air flow (blue arrows) is four (!) times faster than speed in which the individual folds move, which is a big advantage when it comes to reproducing music signals with fast transients (cymbals, plugged guitar strings, etc.).

Aperion Audio's Dual Air Motion Transformer tweeter adds clarity, transient speed, and musical finesse to almost any loudspeaker design. A natural fullness in the treble is exhibited-- reminding us why we love high-end audio so much.
The crossover knob allows you to activate the Super Tweeter at 8K, 10K, 12K, 14K, 16K or shut it off. The crossover slope is 6 dB/octave. This gives you maximum flexibility when incorporating these into your system. You can have more or less overlap with your existing tweeter to help brighten the sound at the 8K/10K crossover point, or have the Super Tweeter just fill the void above at the 14K/16K setting.
If you love your Super Tweeter, but want a little less output, you can reduce the output by 0dB, -1dB, -2dB, -3dB, -4dB or -5dB by re-positioning the Knob.
The DST uses a sturdy aluminum alloy metal enclosure to withstand the fast vibrations of Its diaphragm. The aluminum alloy minimizes noise and undesriable vibrations, leaving nothing but the air movements captured in your music. The DST aluminum enclosure not only provides acoustic benefits, but it completes the aesthetically pleasing design.
Answer: Overall, the treble range is more smooth across the high frequency range. The impedance of the Aluminum Ribbon is almost constant, so there is an excellent frequency response curve up through 40 kHz, but our recent upgrades also allow the Planar Ribbon to reach up to 40 kHz.
Answer: While adding any type of additional speaker to a signal chain has the potential to cause phasing within a room, our 1-step crossover design mitigates any phase issues. This 1-step design is not to save cost and space because if we were to add multi-step crossovers into the chain, it would cause a major phase effect and the sound test results would not sound good.
Answer: Most passive bookshelf or tower speakers are great candidates for the Super Tweeter. But, you can also use them with center channel speakers and surround speakers.
Answer: The Super Tweeter connects directly to the binding posts on the speaker you are pairing it with (not to the amplifier!). This parallel connection allows the Super Tweeter to feed off the same signal as your main speaker.Since the Super Tweeter will most likely be sharing the binding posts with your amplifier connection, using wire with spade or ring connections will allow both sets of wires to easily connect to the same binding posts. If your speakers are bi-ampable, you can use one set of binding posts for the Super Tweeter and the other for the amplifier (making sure to keep the jumpers in place).
Answer: If it’s a sealed box, or portable type of Bluetooth speaker, you most likely will not be able to use a Super Tweeter with this speaker.
Answer: We advise you to check the sensitivity level and frequency response of your current speakers. A speaker that has a higher sensitivity level rating than the Super Tweeter might not be a good fit. However, the we've received feedback that the Super Tweeter works great with Bose 901's, Quad Electrostatic 2805, and other full range and electrostatic speakers.
Answer: The crossover setting will have the most effect on the treble sound. If your regular speaker doesn’t produce frequencies above 14 kHz very well, then that would be a good starting point for your crossover. Generally setting the crossover to 14 kHz or 16 kHz will add a nice touch to the treble response.
Answer: As with all cable, we recommend at least 14 gauge to minimize any loss of electrical current.
Answer: The Aperion Audio Planar Ribbon Super Tweeter can reach up to 33 kHz.
Answer: Yes, in fact this is highly recommended to experiment with, so you can find the sound that works best for you.
Answer: You shouldn’t need more than a few feet, but it depends on the distance from your bookshelf or tower speakers binding post inputs to the Super Tweeter inputs.
Answer: Yes, just give us a call to make this request.
