Summary: The W7 is the top of the line. It will change the way you listen to music forever! Pair this with a good sub amp and hear what you've been missing. Downside is that it is expensive but you get what you pay for.
Summary: I installed the 10 w7 in my wife's suv. The mission was: max thump, least space. WOW, mission accomplished!! I chose a vented design. Performance was equivalent to two 10P3's in half the space. I plan to use w7's for all my future projects.
