I just spoke to a rep at Polk and was telling him the reason why I went with the MB Quart Q-series a few years ago was that it was the only top of the line 5.25" speakers that I could it in the stock speaker location of my 93 RX7 doors. I said that the MB Quarts magnets are shallow enough so that it won't require hacking. He said that in June of this year there will be $600+ speakers that will compete with MB Quarts best speakers and that of Dynaudio. And that it will be easier to fit. Has anyone else heard about this? I have Polk in the rear speakers and woofer and for the $$$ I'm content with their sound quality.
