I'm in the exact same situation as you are right now.Hey all, after some more thought and research I called parts express to go over a few options. They suggested that I get tweeters with a resonant frequency that was half of the crossover or less. In this case that means a resonant frequency of 1,250 Hz or less. I found 3 tweeters that met this qualification in my preferred price range. After discussing those 3 options with the staff at Parts Express, I decided to go with the cheapest option to keep cost down as much as possible, the GRS 1TD1-8.

Thank you for all of your help! I'll report back once I have them hooked up.
Can you tell me if you are still happy with your choice. Also, can you tell me what the other two suggestions were?
Thank you very much.
