I personally havent heard Oz audio in a LONG time, but i recently bought a set of Adire audio Kodas and i was floored by how amazing they sound. I have a small honda Del Sol (with the target top //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif ), and the tweeters are in the upper section of the door with the kodas in the stock location. Powered by a Kicker KX 300.2 (75wx2), these things get loud enough to overcome 80mph driving with the top off and windows down.
The best part though, is that i dont have them eq'd at all, and they sound increadable. The highs are not harsh at loud volumes like my Kicker Resolution set was. The kickers i had to turn down the higher end (16khz) -3db AND have the xover set at the -3db attentiun level.
they sound totally natural from very soft to as loud as i can play them.
The low end though is a little lacking because my door panels are full of huge holes. i plan on sealing them up so they are in a small box. plus i still think that they are out of phase :|
