They make a great product and they have good prices. The engineers at Adire are some of the smartest guys in the industry leading the way in motor and suspension technologies. I actually own complete lines of adire equipment and other speakrs as well. We had a ID 12 in my brothers truck he upgraded to Adire Koda Components, his coaxials in the back sounded bad now and his woofer sounded like crap, so we swapped him out for a Vamp 12, basically a dual 4 ohm shiva, was for a OEM client. Was night and day difference. I had customer swap out focal tweeters for adire tweeters from the koda component set. Loved the new tweeters. There is tons of stories like that. There is alot that goes into woofer design. I can talk hours about it etc how to make a woofer sound good but I wont.

Thats my 2 cents.
