Depends on OP's room size, maybe he could get away with twin PC-2000 which do come in the piano finish and save some dough as well.
There's also a Rythmic FV15HP-SE [Ported in Piano Black] which is a close match to PB3000 [I think] in performance or at least was to PB13Ultra which PB3000 directly replaced.
Honestly, all of the subs mentioned here would provide tons and tons of high-quality bass and all of them are overkill, just some more than others
