Aperion RST Aluminum 3-inch Ribbon Super Tweeter Speaker Pair MKIIair
This APERION Super Tweeter features a true ribbon design, which uses a 20 μm thick (0.02mm) aluminum ribbon strip. Due to the lightweight and thin ribbon size, it is ultra-responsive to transients and provides the accurate upper frequency detail. The clarity of this speaker brings a sense of lightness and heightening the overall mix without any harsh or distorted traits. The impedance of the aluminum ribbon tweeter is almost constant, so it maintains a consistent frequency response curve in the higher frequency band range up to 40 kHz. True ribbon tweeter designs are able to handle a higher SPL than planar magnetic. Naturally with the true ribbon design, an electrical current can’t directly touch the ribbon so we employed a transformer that reaches up to 60 kHz, which requires two pieces of exceptionally strong neodymium 2-1/8” (55mm) by 3/8” (10mm) magnets to produce the linear magnetic field. The entire magnetic, ribbon, and damping material are enclosed in heavy-duty steel chamber. Overall, this ribbon tweeter design allows for minimal distortion compared to the Planar Magnetic Super Tweeter, and along with the longitudinal shape of the ribbon, the true aluminum ribbon super tweeter creates a delicate and spacious sound field.

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.

A 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
Aluminum Ribbon Tweeter

This is not just any normal tweeter... While most tweeters max out at around 20K, the APERION® Aluminum Ribbon Super Tweeter extends another 20,000+ Hertz above that, reaching up to 40,000 Hertz and providing an ultra smooth, clean high-frequency response for the ultimate listening experience.

5-point Crossover + OFF

aperion-aluminum-ribbon-super-tweeter-5-point-crossover

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.

The first generation used a planar-magnetic, flat style ribbon tweeter and has become very popular since its release in late 2018. After seeing the results and popularity of the original Super Tweeter, we jumped back in the lab and got to work on our new, Aluminum Ribbon Super Tweeter. The efforts and hours of product development did not go unwarranted. To fully understand the internal structure of our Aluminum Ribbon Super Tweeter, we disassembled one of them to present the complexity of the design diaghram.

There is an APERION ultra-thin aluminum sheet in the middle of the horn, with a thickness of just 45µm, and this is the core component of the aluminum strip. While the aluminum ribbon tweeter utilizes magnets, the key ingredient was to combine the voice coil and diaphragm into one. This clever design allows the diaphragm to be fully driven in the magnetic gap. The diaphragm is flat and light, without any phase issues, which allows for a high energy transfer and minimal distortion. All of the design characteristics encompass a higher frequency response up to 40 kHz, and the crossover and treble adjustment knobs allow for easy control of the dynamics and transient characteristics, without interruption of sound. The crossover slope is 12 dB/octave

Dynamics are a crucial component for a speaker dedicated to reproduction in the high frequency range as the ear is most sensitive to these frequencies. Knowing this, our engineering team was sure to test all aspects and performance of this speaker to ensure that the APERION® Aluminum Ribbon Super Tweeter would integrate well with many different types of speakers. We recommend pairing it with speakers that have a sensitivity rating between 85-95 dB. It can be used with full range speakers, floorstanding tower speakers, bookshelf speakers, center channel speakers, surround speakers, and works with speakers containing woofers ranging in size. Not only will they enhance any Hi-Fi audio source during playback, but also compliment DVD, Blu-ray and other sources to allow enjoyment of the true, full range of audio.

At Aperion we break the tradition of “big-box” retailer thinking and mass distribution channels. These channels always look for ways to drive the costs of the products down, usually resulting in a sub-par product. We have the opposite thinking and rather than going cheaper with the parts to fit a retailer-distribution mold, it allows us to invest the costs of production to where it really counts, the speaker itself. This means better high-end components, robust internal capacitors and inductors, powerful drivers and tweeters, and overall the best sound for your buck!
