I know their research has said that flat spin data leads to a 90% predictor of best sound. but thats within a price range I believe so 300 dollar speakers vs 300. I dont think this means 300 dollar jbl 308 sound as good as their higher priced competition. maybe it does...but when I audition I am still more impressed by higher priced speakers within the line.
