I hardly think that speaker technology is advancing such that ten year old speakers are necessarily inferior to newer models. There are MANY older designs that are terrific sounding and it is really more a matter of personal taste than technical advancement that will determine what is best.
The only concern with age is the matter of some speakers deteriorating with time. The use of rapidly deteriorating foam type surrounds on woofer and midrange cones is no longer common, so chances are that something ten years old will have lots of life left.
My current speakers are a little over ten years old and I have no concern over their age. The woofers use old fashion pleated paper surrounds--a construction that is known to endure for many decades. I recently bought a "new" midrange driver to replace that which came with my speakers. My best guess on its date of manufacture is somewhere around 1939. This is the best sounding midrange I've heard of any type; so much for technological advances.
