Review on Aperion Audio Planar Ribbon Audiophile Frequency by Stacy Duncan

I ordered these in white to match my new white Wharfedale Diamond 11.4. Amazing combination! They are easy to connect and set up. I haven't had any audio issues with comb filters or other audio issues that people mention about super tweeters. All I heard was more detail, airy holographic FX sounds, longer sustain on piano and strings. The general presence was closer and more immediate, but not accompanied by unwanted brightness or listening fatigue. I would not recommend them to anyone who has speakers that are known to have high frequencies. Tuning and tweaking is just as much fun, as the buttons on the back make it quick and easy to test each setting. I suggest mounting them on top of your speakers to match the tweeter driver in the baffle for proper integration. Your ears will tell you when it's right :) I chose -2dB and 12kHz for my room with Diamond 11.4s. Oh yeah, they look great too if you're worried about them sitting on your speaker. At least mine is white on white with a black grille.
