How to guarantee a speaker's performance for five years At Acoustic Research we make our own drivers. And we test them to unusually high standards. Woofers and tweeters that don't meet these standards don't belong in AR speaker systems. They belong in the 'reject' pile.
Every individual AR driver is tested before installation in a complete system for mechanical stability, distortion, and frequency response. Many don't get through, as our photograph indicates.
But this means that we can be sure about those that do make it. Sure enough that, after a test of each finished speaker system to a tolerance of =1dB over its entire operating range, we can guarantee the speaker's performance for five years.
The AR guarantee says, not just that the speaker will operate, but that it will perform up to the standards of our published specifications. For five years. If not, we pay the parts, labor, and freight costs that it takes to put it right. We will even supply new packaging if needed.
Free.
Sound extravagant? Not really. Rigorous production testing doesn't leave much to go wrong. And that's not extravagant.
That's just good business.
