I have a Hammer subwoofer and 4 Europa Max speakers. I have known Roy almost 30 years. He is a genius and perfectionist, and I have more respect for him than I can articulate. He would be horrified to know I am using his speakers for home theater. A tweeter blew in one of my Maggies, and I used the Europas in my reference system while waiting on the new one. I was amazed at how well they sounded. Placement and good stands are a must. I reccomend them highly. If you call GMA, you will likely get him on the phone, and he will talk to you as long as necessary. He's just a first rate guy.
