I have a nice like new 10" Adire Brahma ...dual 2 for $275 shipped....bish is heavy but they work well in small sealed boxes and would sound great on 600 rms but it can handle upto 1600 rms if you ever want more power ...//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
I also have a DD 1510 dual 4 for a little less....
The tdx is identical to the d9 with the exception of the cone/dustcap color, if that helps any. Neo motor with honeycomb nomex cone. They are rated for 500 watts, and 600 would be perfectly fine.let me find some info on these and get back to u how much power does it need would 600 clean power work
