i am biased because i run diamond audio myself... they <3 more than rated power

 

is the model i listed one of their higher end lines? have u heard them?

 

i run the d3 series in my car (its there bottom of the line stuff) and i love them

 

oh really, then i should be more than happy with these.

 

agreed, we run the DAT D662s set. Good speakers, the only complaint I have is the midbass is a little weak and breaks up at high volumes, but the midrange is excellent and the silk tweets are smoooth at the same level.

That DAT set you're looking at seems a little high priced. I think the same set(maybe a lil older) is only $159 from onlinecarstereo,com.
I believe vnnovations(or whatever it called) on ebay sells manufacturer refurbished DAT hex series, for about the price of that s500 set at sonics. You might want to check that out. Awesome speakers for the price

 

diamond audio all the way..

 

i had the polk db6501 in my old pickup as a replacement for my front, the sound was nice based on the music i listen to most of the time it sounded the best without changing the passive xover switch at all

 

im biased, had polk audio comps and had no complaints about them... never tried the Diamond Audio comps
