Ok, have decided to take the plunge and get an SVS as my little REL keeps bottoming out. Do I go for the PB2 plus or ULtra? Looks are not an issue as I have a dedicated room 5m by 3.5m, Also can anyone tell me roughly what the difference in import tax and delivery charges would be between the two? Have already made a super heavy duty isolation platform for it from concrete acoustic tiles and MDF as my AV room is upstairs. Any answers, advice and or comments would be appreciated.
