Buy now $950, same as my previous offer divad1 (286 • 7:27 am, Mon, 30 Junhow old is this one hillyhunter007 (161 • 1:30 pm, Tue, 1 JulI'm not sure, but given SVS finished production in 2017, that would make it about eight years old. chris_slater (154 • Tuesday, 1 July 2025ok would you take 950 for it today? hillyhunter007 (161 • 1:31 pm, Wed, 2 JulI've already had an offer for $950, thanks. I'd recommend putting in a bid. chris_slater (154 • Wednesday, 2 July 2025Hi, bit new to audio gear and while this SVS SW looks good Im a bit concerned about the age. How much use has it had and in association with what amps ? What sort of music has it been predominantly used for ? estcarp1 (8 • 2:00 pm, Sun, 6 JulIt has its own amp with feedback control which was connected to the line-level Sub output of the Anthem AVM70 pre-amp. It's had moderate use playing mainly classical music. There's no deterioration of the surround and it looks like new. It won't disappoint. chris_slater (154 • Sunday, 6 July 2025I hope it's not too late to put a plug in for Chris, since I bought the other SB13-ultra he sold last week. It's in pristine condition, boxed with manual and sounpath isolating feet. Sou is amazing. Thanks again, Chris! sultanoswing (479 • 7:32 pm, Sun, 6 JulThanks, Curtis, much appreciated. chris_slater (154 • Sunday, 6 July 2025
