In this video, I'll be testing out the Aperion Audio DST super tweeter on my Wharfedale Denton 85 speakers. I'm also going to share with you the measurements I am getting from the tweeters and a sound demo to illustrate the difference it makes.

About This Video

Welcome back to the channel—I’m Colin, and in this video I’m answering a question I see all the time: do super tweeters actually do anything, or is it just “music for dog hearing”? Aperion Audio sent me three of their super tweeters to test, and I walk through why you’d even want one in the first place—mainly to compensate for treble roll-off that a lot of speakers still have in the real world. I also explain why the effect isn’t limited to 14kHz and up, because the crossover isn’t a hard cut; the output slopes, and in practice the super tweeter can start influencing the response much lower. I compare Aperion’s lineup by price and design: the PST Mark II (planar magnetic), the RST (ribbon), and the DST (dual-firing air motion driver with rear ambience output). Then I show how I set the DST up on my Wharfedale Denton 85—matching sensitivity, wiring via binding posts, placing it near the front edge to reduce diffraction, and setting level. Finally, I share my in-room measurements (DST off vs DST on at -4dB, 12kHz crossover) and sound demos. On my Dentons, the DST made the high end flatter, helped the 12–14k trough, and to my ears it added texture, made decay more apparent, and changed soundstage depth.
