Nice Review!!!I have 3 15L7's and 3 15CVX.
Both are great drivers. CVX has better transient response and has less distortion.
L7 hits harder and has lil more SPL, but CVX goes lower and sounds cleaner.
CVX hits the low notes very nice. However, I don't like how it sounds above 60hz. of course everything is install dependent. My box is 4.7Cu.Ft each tuned to 29hz.
You can't go wrong with any of them. (get the CVX //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif )
