Perspective - It's what's for dinner .
Warranty? Pfft! Seriously, at $800, screw worries of any warranty. Anyone who knows speakers know this; there are generally only a few things you need worry about concerning age of a speaker...dried out caps in the xover (usually takes 20+yrs), and foam surrounds (can rot between 8-12yrs, depending on the climate/conditions). But even in the latter case, foam surrounds are easy to replace yourself. Only wankers "throw them out" solely because of rotted surrounds. Essentially, there is no good reason why quality speakers won't last you 20-40+ years! Yes, dead serious here. But then, what do I know....I've only made a dozen or so sets...and still have and use the sets I kept from over 20yrs ago.
