I live in Canada, and buying a sub online can get alittle expensive after shipping/handling, exchange,duty, etc. So i have been checking out some new and used stuff. In my local paper, a guy is selling a Klipsch 12" sub for $225. It is 5 years old. I was looking at them new and up here they are $669, and they look the same.Is a 5 year old sub worth buying?(last another 5 years), or should i save my pennys and wait to buy a new one. I want a decent sub, but i don't want to buy something if it's lifespan is running out. What would you guys do? If it sounds good buy it? Thanks in advance!
