I bought a very big sub from them 15+ years ago for HT. I think it was the SVS PB12-NSD/2. I live in Ohio so i picked it up. I had it for a few years, it was hard to tune in, because of the two styro foam plugs. The driver developed a problem and I thought I could get it serviced. Nope. They really didn’t want to touch it. They wanted for me to buy a new sub. I inquired about buying the driver and replacing it myself. Nope. Sold it at a garage sale for next to nothing owch! Years later I visited a stereo/home theater store looking for stereo subwoofers. They told me they had problems when SVS was accepted as a brand. SVS was still selling direct to consumer and were giving better prices??? Not a great business model. Long story short, not a big fan of SVS. Right now, I am a fan of Rythmik subs for music.
Interesting. When you inquired about the replacement driver from them, what was their response? Perhaps it's not available anymore and since SVS subs are not very costly, the cost of getting a new sub may be more practical than repairing the old one. Either way, your experience seems to suggest that after-sales support is less than satisfactory.
