I use a pair Satterberg MW-2's. They are very rare, seldom seen. Prices are usually low because not many people are familiar with them. They were designed in the early 80's specifically for 15 ohm LS3/5a's. They have an internal crossover that passes the signal to the Rogers. There was a great review in the Absolute sound about that time also. They were made in Portland, OE. The sound is continious, smooth and definately full range. I know where there might be a pair for sale, not sure it he has the original boxes, 87 lbs. net each. Please let me know if you are interested in more info. Good luck, great listening.
