## Description

desertcart.com: Aperion Audio PST MKII Planar-Ribbon Super Tweeter Pair for Home Theater Stereo Speaker HiFi Audiophile Ultra High-End Frequency Response up to 40kHz (Stealth Black) : Electronics

Review: Best audio tweak I have purchased - I bought these super tweeters since my Caintuck Audio Betsy open baffle speakers start rolling off in the treble above 10 Khz, although they still have some response to 20 kHz, so I wanted to get a flatter treble response in that region, or at least up to about 15 kHz where my 60 year old hearing starts to roll off according to test results. Since these Aperion super tweeters have an adjustable crossover from 8 kHz to 16 kHz and sensitivity adjustment by -3 dB to 0 dB, I was able to dial in the treble response I like. I found the best settings for my setup to be 10 kHz cross-over frequency setting and 0 dB sensitivity setting. I found the best position for the Aperion super tweeters to be on top of the Caintuck Betsy's open baffle, centered laterally on the axis of the speaker. With the Aperion super tweeters in my system, in addition to being able to hear some high frequency tones from such instruments as triangles, celestes, and cymbals that I could hear through some other speakers and through headphones, but which I could not hear through the Caintuck Betsy speakers, I was surprised to also hear faster leading edge transitions (aka attacks) even on bass instruments, which made string plucks pluckier and drum thwacks more impactful. I probably should not be surprised at this result since faster temporal transitions require wider bandwidths to be reproduced accurately. Unsurprisingly, I also heard more open and reverberant space reproduced from recordings. I was very glad not to hear any undue and irritating over emphasis of sibilance from adding the Aperion super tweeters. I also do not hear any noticeable so-called "comb filtering" (really acoustic interference fringe) effects with the Aperion super tweeters in my system with the settings listed above. I presume that this is because the drop in the Betsy's frequency response above 10 kHz and the turn on rate of the Aperion's crossover set on the 10 KHz setting are such that there is minimal overlap from the two in the 10 kHz to 15 kHz regime. The super tweeters are also well built and robust. I dropped each tweeter a couple of times during my setup testing while moving them around to find the best location, even chipping the finish on one of them, but I heard no audible degradation in performance after those drops. I don't recommend doing drop tests on these, but having accidentally dropped them I thought their robustness was notable. I should note that the Aperion super tweeters did sound to me a bit smoother and more refined after 24 to 36 hours of burn-in, but they are by no means harsh nor unrefined right out of the box. (Whether that is due to changes in the speaker's sound from burn-in or to accommodation by my sensory system, I do not know, nor do I care.) Overall, the Aperion super tweeters have been the best tweak for my audio system that I have ever bought.
Review: Excellent product - These super tweeters are one of the best “tweaks” you can make with your system. Their adjustability makes them easy to integrate with a variety of speaker styles and designs. It took me a while to figure out how to best incorporate them into my system. I have large electrostatic panels, so placement can be problematic. I settled on placing them on 36” tall stands between and a bit recessed from the main speakers. This seems to mitigate any comb filtering effects that can occur when place on top of a speaker. The effect is more than a little subtle. They have transformed the sound in a big way. In addition to adding air and presence, definition and focus of the higher frequencies have improved dramatically. All of this has been accomplished with zero sibilance or shrillness to the sound. The better the recording, the more pronounced the effect. I highly recommend these to anyone who has speakers that may need a bit of help with the high end. Unlike some other super tweeters that only operate in the inaudible high frequency range, these have an instantly recognizable impact on sound.

## Features

- The Aperion Audio Super Tweeter is a high-fidelity compliment to any home audio system. They add a subtle touch to the high frequency range and blend seamlessly with many brands of speakers.
- Designed to reside on top of your existing speaker, the Super Tweeter will slightly boost the frequency range of 8,000 Hz to 40,000 Hz and employs a high pass filter with 5 preset crossover points.
- Unlike a horn tweeter, the Super Tweeter delicately handles high frequencies, bringing a new dynamic to your sound field. The Planar Magnetic Super Tweeter works best with speakers having 85 to 93 dB efficiency.
- Please do not expect this tweeter to be extremely loud. This is a special tweeter which adds a subtle boost to the upper register frequencies. Please note the efficiency of your speakers to ensure the Super Tweeters are compatible with your existing speakers. If you have any questions, please contact the customer service team at Aperion Audio.
