Pros: Enlarged Folded Motion XT tweeter offers 40% more radiating area for lower distortion and effortless high-frequency dynamics. Triple 6.5-inch aluminum woofers deliver robust bass extension down to 31Hz.
Cons: Forward upper treble character can sound unforgiving on compressed or bright source material. 4-ohm nominal impedance demands an amplifier with generous current delivery.
