I don't know much about the Eminent speakers but they have always intrigued me. I currently have two sets of ESLs. Quad ESL 57s and Music Reference ESLs. I shied away from subwoofers because I thought they made things a bit too complex and I never could get used to the idea of bass being driven by plate amps. So I listened to my ESL 57s with my OTLs and enjoyed what bass they could muster, which quite frankly was more than I expected. Then Roger Modjeski introduced me to his Airspring woofer system that he uses with his ESLs, which by design only go down to 100 Hz, so they require something to provide the bottom end. He fixed up a Class A/B solid state amp with a low pass filter for me and I made two of the woofer boxes myself. Once I put that in my system there was no going back.
Today I use a Beveridge RM-3 as the crossover with 100 Hz boards, my OTLs on top driving the ESL 57s or the MR ESLs, and a Luxman M-02 driving not 2 but 4 woofer boxes spread asymmetrically around the room. This has done more to improve the sound in my room more than anything else I have ever tried. So for me biamping was the ticket and I imagine you can attain the same effect with good subwoofers. In fact I'd recommend checking out the Audiokinesis Swarm which is a nice little system that would play well with the LF8s.
