I'm looking to add a sub-woofer to my stereo system (it will also serve a secondary role in the soon-to-be implemented cinema system). I was initially going to go down the REL or KEF or BW route, but having browsed these forums, it seems SVS are held in very high esteem and also seem to offer amazing value-for-money (especially now that the £/$ ex rate is so good....). However, it seems to me that a purchase of an SVS is open to some pitfalls. Would I be right in thinking that it is impossible to audition an SVS prior to purchase and therefore it really is a case of buying on blind faith? Of course, if you don't like it then returning it is going to incur some pretty hefty shipping charges. And whats the situation wrt to repairs etc? Any advice is greatly appreciated especially from people who have purchased SVS. How did you go about ascertaining that an SVS was right for you and that it was the sound you were looking for. If I decide to go ahead, I would probably be interested in something like the PB1 or PB2 Plus. What is the equivalent REL or BW model. Thanks in advance.
