Carl, they are SL3000's. Mikey, if you do nothing else, upgrade to the RD0198-1 tweeters available from Polk and add some spikes...makes a huge difference. If you join Club Polk before ordering the tweeters the price will be $48.00 each with free 2nd day shipping. They are a drop in replacement. If you want to get serious, upgrade the crossovers. I have a few tricks when upgrading the crossovers, so feel free to contact me about that.
