two marty cubes or similar size/tuning cabs with 390ho's would be a great start. performance would be roughly the same as a pb13u, but with better upper bass response.
two subs is almost always better for room response than one sub.
later on, if you need more bass and you may not, the system could be upgraded with more 390's or integrated with 460ho or um18 no problem.
