This was the original question, which clearly is subjective in nature, and all responses recognize this but nevertheless reflect a preference, regardless of what kind of loudspeaker and design techniques are being used.
I am not reading the question as such... subjective in nature.
Perhaps OP was asking... "How would a Cornwall Compare to a RF7?". In that, what are the sonic and tonal differences and unique qualities to each... not which one is "Better".
if we answer in this way, perhaps OP would have a better understanding as to which speaker, and more specifically which speaker line, he might prefer.
