The Adire's are I believe 3 year warranty's. And I got this straight from JL's website:
WARRANTY TERMS
(effective March 1, 2003)
These terms supercede all prior published warranty terms
JL Audio products are warrantied against defects in materials and workmanship for a period of Ninety (90) Days from the original date of purchase.
Warranty coverage is extended if the product is installed by an Authorized JL Audio Dealer OR the system design and installation integrity are evaluated and approved by an Authorized JL Audio Dealer (in writing on the original sales receipt).
The available warranty coverage extension varies by product category, as follows:
Subwoofer Drivers: One (1) Year
So how do you figure that you got a 2 year warranty? Which one sounds better now?
