Short answer: the Genelec 8331A for better sound quality, the Edifier R1280T for the lower price. The Genelec 8331A ranks #1 of 100 powered bookshelf speakers, rated 4.8/5, at $5,750. The Edifier R1280T ranks #89, rated 3.1/5, at $119.99, $5,630.01 cheaper.
The case for the Edifier R1280T: ASR’s review found useful moderate-level bass output from an inexpensive powered pair. Watch for: Preference scores of 2.41 standalone and 5.02 with an ideal subwoofer reflect substantial tonal limitations, not just missing bass.
The Genelec 8331A is the more accurate, deeper-bass option. Erin’s Klippel measurements support its reference-monitor credentials: a 1.4dB response span from 300Hz to 5kHz, low listening-window and predicted-room irregularity, and preference scores of 6.57 standalone and 8.51 with an ideal subwoofer. Its measured preference score, a predictor of how neutral it sounds, is 6.57 against 2.41 for the Edifier R1280T. Its bass reaches about 49Hz before falling 3dB, against 63Hz for the Edifier R1280T. The catch: Expensive, with studio-oriented XLR connectivity rather than consumer streaming.
Buy the Edifier R1280T if the price is the priority over sound quality, or the Genelec 8331A if sound quality is the priority over the price.

Edifier R1280T: $119.99 per pair Amazon eBay
Pros: ASR’s review found useful moderate-level bass output from an inexpensive powered pair. Remote volume and bass/treble controls make it easy to use without separate amplification. Measured bass reaches -3dB around 63Hz. Measured bass extension of 63Hz (-3dB).
Cons: Preference scores of 2.41 standalone and 5.02 with an ideal subwoofer reflect substantial tonal limitations, not just missing bass. The response spans 5.5dB from 300Hz to 5kHz, and listening-window narrow-band deviation is 0.650. Resonances and treble unevenness affect reflected sound too. Listening height is important, and high-level compression changes the balance.

Genelec 8331A: $5,750 per pair B&H Photo Video eBay
Same family: the Genelec 8341A (larger bookshelf, rated 4.8/5), the Genelec 8351B (larger bookshelf, rated 4.8/5), the Genelec 8361A (larger bookshelf, rated 4.8/5) and the Genelec 8381A (floorstanding, estimated 4.9/5).
Pros: Erin’s Klippel measurements support its reference-monitor credentials: a 1.4dB response span from 300Hz to 5kHz, low listening-window and predicted-room irregularity, and preference scores of 6.57 standalone and 8.51 with an ideal subwoofer. The coaxial mid/tweeter and concealed woofers maintain coherent radiation as listening position changes. Bass reaches -3dB around 48Hz, and GLM adds level, delay and room-response calibration. Measured bass extension of 49Hz (-3dB).
Cons: Expensive, with studio-oriented XLR connectivity rather than consumer streaming. The compact woofers still limit deep-bass output, and the review reports protection muting when pushed beyond its operating range. GLM calibration hardware is an additional purchase. Its excellent tonal score does not remove the need for a subwoofer or larger monitor at demanding levels.
