It seems pretty confirmed that the CW's are great speakers if they are seriously modded. Thanks for the update about that. Some will see this as a great opportunity -- like buying a house with "good bones" and then making a dream house out of it. Others will see this as a deficiency in a $7k speaker. I suppose it comes down to what you're comparing it to. The value of the Voltis, then, seems to be that they are prêt-à-porter.
I wonder how much time and parts the Cornwall IV need. They're price at $6,598.00 and Rivals are $8,900.00, a $2300 difference, or about one-third more expensive.
