Buying a 10 years old loudspeaker

Its (not "it's"=it is) life expectation is infinite -- within scientific limits of error.

Assuming the speaker has been well treated up till now, that is: check the drive units, their surrounds, the sound (is there homogeneity between the two spkrs); if possible, get someone to check the dc resistance of the drivers, just in case. Regards

Good tips mentioned . I also think you should do a gut check and get a feel of who you are dealing with and the honesty and true info you get from the buyer is real important..Anything can happen down the road,but in most cases a 10 year old speaker ( under normal conditions ) is not a problem.........Simply because the speaker has lasted 10 years has to say something for the quality built in.......
