Aperion PST Planar-Magnetic Ribbon Super Tweeter Speaker Pair MKII




This Super Tweeter is a planar-magnetic, flat-ribbon tweeter consisting of Kapton film with a pattern of aluminum conductors. The crossover network used non-inductive resistors, and use film semiconductor capacitors. A linear phase response provides time coherent sound reproduction, allowing for an accurate sound stage.

What is a Super Tweeter speaker? Put simply, it’s an additional tweeter unit which covers a wide and extended high-frequency response, beyond that of your existing loudspeaker’s integrated tweeters.

Many loud speaker systems have poor high frequency performance. A Super Tweeter specializes in ultra-high frequencies and is used in conjunction with a bookshelf or tower speaker. Its purpose is to create a more realistic sound field, often characterized as "airiness," that enhances the listening experience. Super Tweeters are sometimes found in high fidelity speaker systems and home theater systems. They are used to supplement the sound of tweeters by reproducing frequencies which the existing tweeter may produce only with a narrow polar output, or perhaps with distortion. A Super Tweeter speaker provides auxiliary high frequency effect, detail, density and texture that can enhance your existing system’s sound field with width, depth and enhanced timbre.  

Aperion Super Tweeter is generally intended to respond well into ultra-high frequencies over 20 kHz, the commonly accepted upper frequency limit of human hearing. Super Tweeters are ideal for taking advantage extended-range audio formats such as vinyl, SACD, FLAC, UHD Bluray and other high-fidelity products.


Key Features

Extended High Frequency Flat-Ribbon Tweeter


This is not your normal tweeter. While most tweeters max out at around 20K, the APERION® Planar Ribbon Super Tweeter extends another 20,000+ Hertz above that.


5-point Crossover + OFF


Choose between 8, 10, 12, 14 or 16 kHz to set the Super Tweeter floor for the perfect blend with your speaker. The "OFF" position renders the Super Tweeter inert. The lowest setting, 8 kHz, will provide the most overlap with your existing tweeter while the highest setting, 16 kHz, will have minimal overlap, picking up at the top-end of the range. The crossover slope is 6 dB/octave.



Treble Adjust Knob


Too much of a good things? Use the treble adjust to reduce the output of the Super Tweeter. Just flip the switch and adjust to taste, up to -5dB.


Easy Connection


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. 


Beautifully Curved Cabinet 


The finishing touch for every Super Tweeter Speaker is a matte black/white or piano-black lacquer that’s so right for every decor, your coffee table will be jealous.


5-Way gold-plated binding posts


The 5-way gold-plated binding posts let you connect your speakers any which way you choose: bare wire, banana plugs, spades, round pins or flat pins.

    Extended High Frequency Flat-Ribbon Tweeter

    This is not your normal tweeter. While most tweeters max out at around 20K, the APERION® Planar Ribbon Super Tweeter extends another 20,000+ Hertz above that.

    6-Position Crossover Knob

    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.

    6-Position Treble Adjust Knob for Attenuation

    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.

    + FAQ


    What's the difference between the Aluminum Ribbon Super Tweeter and the Planar Magnetic Super Tweeter?

    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.

    Will adding a Super Tweeter cause phase issues?

    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.

    What kind of speakers will the Super Tweeter work with?

    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.

    How do I connect the Super Tweeter speaker to my passive 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).

    Can I use the Super Tweeter speaker with my active (powered) or Bluetooth speakers?

    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.

    "Will the Super Tweeter work with my electrostatic, full range, or professional audio speakers?"

    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.

    How much will the Super Tweeter change the treble response?

    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.

    What speaker wire is best for the Super Tweeter speaker?

    Answer: As with all cable, we recommend at least 14 gauge to minimize any loss of electrical current.

    What’s the highest frequency the Super Tweeter will reach?

    Answer: The Aperion Audio Planar Ribbon Super Tweeter can reach up to 33 kHz.

    Can you adjust the crossover frequency while music is playing?

    Answer: Yes, in fact this is highly recommended to experiment with, so you can find the sound that works best for you.

    What length of speaker cable do I need?

    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.

    Can I buy an odd number of Super Tweeter speakers?

    Answer: Yes, just give us a call to make this request.
