@bdp24 , I would not recommend the LFT-8B even though it is superior to most box speakers it is horribly inefficient and has a predictably weak mid bass as it switches from being a line source to a point source. You can not switch gears like that with a loudspeaker. It is also the weakness most Martin Logan speakers have. The volume of line source loudspeakers falls off much slower than point source speakers so as you move away from such loudspeakers you lose the bass. Imaging also fractures. For those of us using line source loudspeakers this problem has significant implications for subwoofer use. This is a problem I wrestled with for years. You have to create a line source subwoofer system capable of reaching up to the frequency that the woofer panel starts switching to point source. In this instance that is just too high for any subwoofer system. With Maggie 3.7i's you are talking about 250 Hz
which is doable but not the way I do it as I cross at 120 Hz. You would need to make two subwoofer towers as high as your ceiling. I would use 10" subwoofers spaced two feet apart. An 8 foot ceiling would require 4 drivers each side. Making corner enclosures would be a novel approach.
