hmmm who could you be talking about //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
The cvx was my favorite driver in the great 12 challenge. It had a nearly flat response from 30-60hz iirc. For the money I dont think the CVX can be beat. The m3's are nice drivers I would say its a toss up between the two. Whichever your local dealer offers the best price/warranty on would be what I would go with....
edit i just read where you said you will be running a 1000d on the m3s or a 1500.1 on the cvx's, for that reason I would go with the CVX"s. I'm guessing those are both around the same price, and the cvx's are the better deal
