I have the SVS 20-39 PCi and it THUMPS!!!! The people at the SVS board on hometheaterspot tried to tell me to go w/ the plus series, that it has more headroom, but I am not an audiophile and figured the PCi would be enough for me and BOY WAS I RIGHT!!! WOW....I can't believe the bass that comes from this thing...and I really can't believe people get two or three of the subs that are twice as much as this one!!!

Anyone thinking of getting an SVS and are on the fence about what series to go w/.... believe me..the PCi will THUMP w/ the best of them!!!
