I've been pulling my hair out trying to decide on which SVS. My final decision is the 25-31CS+. Just placed my order and now the anticipation starts. I'll be replacing my Polk PSW650. The Polk did ok but I just haven't been very impressed with it ever since I bought it a year ago. Before I placed my order, I went out to my local dealer to see what they had. They tried to sell me the Mirage bipolar 8" sub for $800. I even sat down at their computer and showed them the svs website (they never heard of svs). Of course they want to sell their product, so I got the speach about well how long has svs been around, we offer great customer service, the svs design has been tried before, good sub manufacturers are moving away from down fireing subs etc. They almost had me swayed from svs, but only for a second. Local dealers just hate hearing internet, especially when I told them I have the Outlaw Receiver and am considering svs (they hadn't heard of Outlaw either). Hopefully my new SVS will make me Proud!
