Short answer: the Edifier R1280T. It ranks #95 of 108 powered bookshelf speakers by sound quality, rated 3.1/5, at $149.99. The PreSonus Eris E3.5 2nd Gen ranks #45, rated 2.5/5, at $99.99, $50 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Edifier R1280T is the more accurate, deeper-bass pick. A cheap, simple powered bookshelf pair with a remote and bass and treble knobs, no amplifier needed. Its measured preference score, a predictor of how neutral it sounds, is 2.41 against 1.51 for the PreSonus Eris E3.5 2nd Gen. Its bass reaches about 63Hz before falling 3dB, against 80Hz for the PreSonus Eris E3.5 2nd Gen. The tradeoff: Preference scores of 2.41 standalone and 5.02 with an ideal subwoofer reflect substantial tonal limitations, not just missing bass.
The case for the PreSonus Eris E3.5 2nd Gen: Small desktop monitors with bass and treble controls on the back to adjust for desk or wall placement. It has an adjustable EQ, which the Edifier R1280T lacks. Watch for: The stock response spans 7.2dB from 300Hz to 5kHz and has a strong rising trend of about 1.27dB per octave, emphasizing treble over the midrange.
Buy the Edifier R1280T. It is rated higher for sound quality, and saving $50 with the PreSonus Eris E3.5 2nd Gen does not make up for the sound-quality gap.
