I think I have a plan. Two Red Dragon M1000 mono amps (500/1000 WPC 8/4 ohms), a crossover from Marchand, and advice from Revel on crossover frequency/slopes...was leaning toward the Bryston crossover since it is adjustable, but think if I get all three experts to converse can nail the right specifications. Thanks to Ryan from Red Dragon, Phil Marchand, and Jason from Revel...
Of course, this will also mean I need additional power cords, and another XLR interconnect...
Should at least rival the performance of the LE 1 and I am confident it will surpass it, which was pretty phenomenal to begin with.
I also am anxious to hear the improvement from another sorta home made tweak. Arnold from Core designs sent me a couple extra shelves for one of his racks; I filled the cavity with sand, and mounted some Herbie's Tenderfeet underneath and the subs sit on top of these...should decouple the subs from the floor, and it looks awesome with some LED lights underneath...
