Used Subwoofers

HI Folks
Does it make sense to buy a used sub woofer. For eg: i am seeing a 9 year old SVS PB1000 available in my area for discount of about 40% on current retail price.

My concern is that isnt it a bit too old for Subwoofer, especially considering the capacitors in the boards would be nearing end of life.

Thanks

9rs old is nowhere near end of life for electrolytic caps.. that's more like 25yrs. But that said buying used powered subs is always a bit of a gamble, you don't know if it's had any issues and if it does develop a problem would there be any service information available for it.
