I already have one Vortech and some Koralias, but where would I put the Vortech (s) and could I supplement with the korallia 3 and 4? It's 3 x 5 x 29 with DSB.
I think I would try to put the koralias on the back wall pointing towards the front. This will help hide them from view. Put the Vortech on one end and get another vortech for the opposite end.
