I visited Duke and Lori, but I was so focused on the Swarm that I didn't pay much atendtion to the main speakers. The Swarm deserves everybody's attention. In my listening room there's an 80hz null and a 40hz peak at the listening position. Adding a single sub or even dual subs near the main speakers just reinforces the peak and does nothing for the null. I believe a Swarm would solve this problem. I wish Duke had picked another name. I would love to be able to tell my wife I bought a Harem.
