“While both speakers have objectively excellent off axis performance, two differences are interesting. The Classic Three has wider coverage from about 600Hz to about 1.5kHz, and basically the same coverage over the next octave. Thus, the Classic Three does not share the C3’s overall midrange output bump. Perhaps NHT revoiced the woofer/midrange crossover? NHT suggested to me that this difference in lower midrange directivity may result from the different cabinet shape. Additionally, and surprisingly, the C3’s 1″ dome tweeter puts much more sound into the room above 7kHz than the Classic Three’s .75″ dome tweeter.”
