Interesting JL Audio W7 Review I Read...

If he managed to get a W7 to distort he was doing something wrong. There was a test done a while back pushing supersubs to their limits just to see what they were really capable of. At the 30mmish mark the W7 was still going strong, it beat a brahma by a fair margin. Beyond that the glaring flaws in his "expertiese" have already been mentioned.
