Short answer: the JBL 305P MKII on value, the Genelec 8020D on measured accuracy. The 305P MKII is a fantastic value in studio monitors, though its amps may hiss slightly at low levels. The 8020D’s Klippel-based spinorama shows a flat, well-behaved on-axis response from about 60Hz to 10kHz, but sound power rolls off starting around 500Hz-1kHz as its small 4.1” woofer/tweeter pair begins to beam.
Buy the Genelec 8020D if sound quality matters more than the price. Buy the JBL 305P MKII if the price matters more than sound quality.
