I used to own a set of Focal K2 speakers(3 way system with 1" tweeter, 3" midrange, and 6"midbass) and I thought they were real good (although I did eventually destroy the midbasses). The only reason why I don't still have them is because they weren't loud enough for my SPL system since I am a volume maniac. I find Focal makes really good speakers but just remember that a DSP is important too. My K2 speakers didn't really impress me that much until I got the Audison bitOne DSP unit installed and my system tuned. That is when they really came alive and sounded good...it played all my metal music such as Metallica and Pantera really well. Overall, I would say yes, they are good speakers but just make sure they get enough power and I would seriously consider using a DSP unit to really make the music sparkle. I have the Helix DSP.3 now but I would say any good quality DSP unit should work. Good luck and I hope your sound improves tremendously.
Can't (won't) do a DSP. I have a DSP I bought for another car but in the S550 it's fiber optic to the amp and it has it's own DSP. I love the way everything sounds in it already and it gets pretty low although I eventually will add a sub.
Just the highs aren't very crisp.
I also just found out two bad things anyway that may put me back to the drawing board.
One the order from two days ago....they just emailed an stated that they are on backorder and that I can either wait (no date specified) or I can choose another item.....if they don't cancel the order I see a charge back coming.
Second the drop in Focal Components are for a W222 not a W221 (I have a W221). So I have to do some research.
I just want a little brighter highs and then down the road add a sub off the sub channel. Adding the sub will be pretty simple once I get around to it.
Apparently finding drop in speaker is the bigger challenge.
