Short answer: the JBL 305P MKII for better sound quality, the Edifier R1280T for the lower price. The JBL 305P MKII ranks #11 of 58 powered bookshelf speakers at $319. The Edifier R1280T ranks #36 at $129.99, $189.01 cheaper.
What the JBL 305P MKII offers: A fantastic value in studio monitors. Extremely close to the Focal Alpha 50 EVO, almost indistinguishable. Surprisingly deep and wide soundstage. Good horizontal dispersion (~70 degrees). Has a proper limiter that controls output cleanly rather than crudely cutting bass, and holds up well under sustained loud playback with minimal thermal compression. Watch for: Possible slight hissing from the amps at low levels. Rear ported, can be an issue close to walls. A port resonance around 1.6kHz is audible and distracting on some tracks. Midrange is somewhat scooped rather than flat for a studio monitor, and treble runs about 1.5dB hot - Erin’s Audio Corner recommends using the -2dB treble shelf switch. Vertical dispersion narrows around the crossover, so try to stay within about 10 degrees of the tweeter axis.
What the Edifier R1280T offers: ASR’s Klippel-based measurements found the woofer handled a demanding bass-heavy track without bottoming out or audible distortion, and distortion stayed low and inaudible at a normal 86dB SPL listening level. Built-in remote and bass/treble tone controls, no separate preamp needed. Watch for: On-axis response is jagged rather than neutral, with a woofer resonance around 5kHz and a tweeter peak near 10kHz that also show up in the directivity data, making off-axis/room response uneven too - the reviewer’s raw impression was “a bit bass heavy and after a track or two, somewhat bright,” and he recommends EQ correction. Vertical listening window is narrow, so the tweeter needs to be angled toward the ears. Pushed to 96dB SPL the tonal balance shifts noticeably, a sign of compression starting even though the driver doesn’t audibly break up.
Buy the JBL 305P MKII if sound quality matters more than the price. Buy the Edifier R1280T if the price matters more than sound quality.
