are these 4 x 6 speakers decent? good SQ?? thanks

 

No offense, but this is about the 4th time you have posted about 4x6's, why don't you go and listen to them, or are you buying them online? Bottom line is that 4x6's are very limited in their midbass response, about the only thing they are going to be good for is upper midrange and the high-end will depend on what the tweeter in them is. I would look for one with a soft/silk dome tweeter. Good luck.
