These are infinity betas.
I’m a huge Infinity fan. I still use my RS1B woofer towers and I have owned a lot of Infinity models over the years. Trust me when I say there are better loudspeakers out there. The years have caught up to them. As an example Magneplaner 3.7s with a good sub will give you everything you want and more. The Magnepan ribbon tweeter is way better than the Infinity Emits and Emims.
