The thing is that most speakers are expected to last for at least 10 years before they begin to give any issues whatsoever.

I purchased the Klipsch RF-7 floorstanders in 2003 for $1500 a pair which means I've used them for more than 2 decades. It was one of the most expensive speakers then, but I needed to get a sound device that could withstand the test of time.

To be honest, those speakers haven't had a major issue since then aside from the rubber surrounds on the woofers, which I spent $150 to replace when they were worn out.

Also, the good thing about Klipsch is that their spare parts are readily available in the market, so you won't spend so much getting them if there is a fault with the speaker.

I don't know the kind of room that you wish to use them in. Could you mind sharing?
