What is it you are waiting for? Is it big or compact?If it has to go in a cabinet, then I still feel the SB-12 would do as well as anything. If can be placed more traditionally, but a room dominating box is not really prefered, how about 2x SB-12s? Just an idea.
It's a combo I've had my eye on for a while and may yet still be considering, pending speculated release dates for a new product due to be released next year.
