RST Aluminum 3-inch Ribbon Super Tweeter Speaker Pair (Open Box)

Most excellent add-on to a pair of Rogers LS7

Open box excellent condition , thanks again.

I purchased a pair of RST MKii Super Tweeters from Aperion. They are certainly not the most expensive tweeters on the market, but they are not cheap either. But, after reading countless reviews where these tweeters improved the sound of Wharfdale, B&W, and other high-end speakers, I was convinced of their quality. I set them up on a 5.3.2 Dolby Atmos System with Kef iQ speakers (the front mains being bi-amped). These tweeters completed my system. They created an airyness that just seemed real and genuine. Headroom and sound stage were remarkably improved. For the first time, I stopped hearing music and started listening to instruments and vocals. I was so amazed, I literally sat for at least 5 hours immersed in the best audio experience of my life. The next day, I watched a few Dolby Atmos movies. OMG, the experience was better than an IMAX theater. The tweeters somehow wrapped the room in a 3D bubble, I could hear sound actually moved around the room, beneath me, next to me, etc.. Do I think they are expensive? Yes. Will I consider returning them? No, absolutely not. These tweeters are built with the best engineering and components available, and that is evinced in the quality of sound. This is a rare purchase where I certainly got much, much more than I paid for. There is a reason I couldn't find any used MKiis on eBay or reverb...everyone keeps them! One caveat, if you put your ear to a tweeter, don't expect much. These tweeters produce sounds beyond the range of human hearing. But, that unheard sound augments the harmonics of audible sounds within the range of human hearing...and that's what makes the REAL difference.
