Those are not related to the British company Rogers. Rogersound Lab speakers were sold factory direct from Van Nuys, CA as an in-store house brand starting in the early '70's. The 3600 model was a 3-way 12" woofer bookshelf model, the second generation designed to compete with the JBL L-100/4310. It was less colored than the L-100, but not as dynamic or as well-built. Because the L-100's can be bought for $300/pr, I don't think I'd pay more than $200/pr for the 3600, if I liked the sound (I don't).
