I have noticed that the depreciation in addition to age is size and brand dependent. Big unknown speakers you are lucky to get 50% more likely 30% of oringinal msrp. Small easy to ship speakers from a well liked ,popular brand, you see a lot of people asking for as much as only 30% off of msrp, just the opposite.
Speaker depreciation: Is there a rule of thumb?
I'm looking at used speakers and wondering if there is a 'rule of thumb' for determining a fair price. I imagine (operative term...imagine) what kind of reviews the speaker received after manufactured, materials used, age and other factors have an impact. Your thoughts?
