I've been using a V6 with a 1048h and 1518t. Recently I got another 1518t as I wanted to try the V6 with two 1518t's. It sounded good in that it gave me the extra bass I was looking for but at the expense of losing some of the higher frequency response. SO, now I want to use all three cabinets at once. Is this possible? Anyone done it? The other possibility is to get another 1048h and run the four cabinets together?
