I was at my dealer were i purchased my b&w cdmnt series speakers and told them i bought a new sub over the internet and that it was a svs. and he said they tried one to just to see how they were . they said they went way loud but are not very accurate.well i just thought how could they bring me down like that ive been loving my svs with music and movies. they said that their velodynes where much better i beleive the hgs series or something. they also said the velodynes are built better and own most of the patents like servo controll and things like that. hope i made the right decision with the svs.
