Re: what's a good center option for a Cabinet that has 20" wide shelves?
There's no way a Horizon would fit in there, it's a monster. The non-recessed Sierra-2 that Todd posted is the best option, but it's rear ported so that might make it sound a little muffled I'd imagine. If Dave releases a Sierra Sat Center that would probably be the ultimate solution.
