Hi, As my first post on this forum I would like to ask your opinion on a SVS PC-Plus 25-31 sub. My HT lacks a sub and I´ve decided to put my money on a SVS sub. Because of WAF my possible choises are limited to the smaller subs and currently I´m thinking about going for a 25-31+ but I want the sub to go down atleast 20Hz. Should I Order it in the factory tuning 25Hz or in the custom 22Hz? I´ve read tons of posts and a few reviews on different forums but I haven´t found anything on how the 22Hz tuning efects the sub in question. Also can someone tell me how low it goes in room. Any ideas or experiences? Or would you recommend the 25Hz and the port plug option.
