DT-Out of what you have listed the Hertz would be my pick. I run the older HSK165 in my Focus. You can find them on
ebay ect. for $200 to $250. The newest one's will run you more coin but IMO they are worth it.
Between the older HSK and HAT Imagine. The tweeter on the Hertz is a little better, the midrange is equal and the midbass is a little better on the HSK. The HAT Clarus line is the competitor to the Hertz HSK line. The Imagine line do a **** good job and can come close to the HSK though.
