Diamond D661's...any good?
 

Any experiences? Anything better for the same money ($200)? I listen to everything so I need a set that will be "flexible".

DLS UP6 components! The whole speaker setup is EXTREMELY SMOOTH...you won't be disappointed.
i'll sell you my slightly used set for $200 + shipping

Rainbow SLC components are also VERY good for the $$. Not sure what the going rate on them are (in the 200-300) range...
If you search threads about the rainbows you'll see a lot of good comments about them.

MUCH better choice here.

I just installed D661S components in the front and D661I integrated in the rear doors. You didn't say whether you'll be adding aftermarket amps for you setup, but I assume you will. I happen to like the Diamond Audio D6 line a lot for all kinds of music, but you will need a good amp because Diamond Audio speakers like a lot of power. I have not recently used any other high end aftermarket speakers, so I can't comment on others, but the Diamond Audio's are great. You will run into problems with installation because the speakers are over-sized and there is not currently any retail adapters to make them fit(at least I couldn't find any online or locally). You will need custom adapters. My car had the Bose system, and the adapters for the Bose speakers are useless for aftermarket 6.5's. I was able to make a 1" thick adapter and 3/4" thick adapter out of MDF that worked for the setup.

Yesss the DLS UP6 from burnurass those would be much better than the Diamonds. :) They're even better than the SLCs in that their highs are more crisp! Awesome price too, the UP6's are going for $260 on ebay.
