I can also vouch for the Focal & MBQuart speakers as many of my friends had them...the Bostons I had in my boat were the Pro Series (seperate mid/tweet)...and I have also had their plate speakers in another car...their high end stuff definitely sounded better than the plates which as Dlr states were etched. My infinity's...that was just in the beginning and as Dlr also says...too tame. The Polks were by far the worst to my ears...OUCH!
