Short answer: the Genelec 8341A on measured sound quality, the JBL 4305P on price. The Genelec 8341A ranks #7 of 113 powered bookshelf speakers, rated 4.8/5, at $7,350. The JBL 4305P ranks #40, rated 4.4/5, at $1,499.99, $5,850.01 cheaper.
What the JBL 4305P does well: The measured 1.5dB response span from 300Hz to 5kHz supports even mids, with a 7.45 ideal-subwoofer score and 45.4Hz -3dB bass extension. It keeps a wired aux input, which the Genelec 8341A lacks. Watch for: Crossover-region directivity changes mean the narrow on-axis span does not describe every listening angle.
The Genelec 8341A is the more accurate choice. An 8.52 ideal-subwoofer preference score and 1.2dB response span from 300Hz to 5kHz place the measured vertical configuration among the strongest tonal performers here. Its measured preference score, a predictor of how neutral it sounds, is 6.75 against 5.44 for the JBL 4305P. The catch: Measured -3dB extension is 47.6Hz, so the larger 8351B and 8361A provide more useful low-end reach and headroom.
Buy the JBL 4305P if the price is the priority over sound quality, or the Genelec 8341A if sound quality is the priority over the price.

JBL 4305P: $1,499.99 per pair Amazon JBL eBay
Pros: The measured 1.5dB response span from 300Hz to 5kHz supports even mids, with a 7.45 ideal-subwoofer score and 45.4Hz -3dB bass extension. Integrated consumer connectivity makes this a more convenient living-room system than many studio monitors. Measured bass extension of 45Hz (-3dB).
Cons: Crossover-region directivity changes mean the narrow on-axis span does not describe every listening angle. Limiting becomes relevant at high output, particularly with bass-heavy music. It suits near- to midfield listening better than the largest high-output systems here. Erin measured about 8dB lost near 50Hz at the highest drive level and reached roughly 93dB unweighted at 2m in-room.

Genelec 8341A: $7,350 per pair B&H Photo Video eBay
Same family: the Genelec 8331A (smaller bookshelf, rated 4.8/5), the Genelec 8351B (larger bookshelf, ranked higher, rated 4.8/5), the Genelec 8361A (larger bookshelf, ranked higher, rated 4.8/5) and the Genelec 8381A (floorstanding, estimated 4.9/5).
Pros: An 8.52 ideal-subwoofer preference score and 1.2dB response span from 300Hz to 5kHz place the measured vertical configuration among the strongest tonal performers here. Coaxial radiation and GLM support precise nearfield imaging and room integration. Measured bass extension of 47.6Hz (-3dB).
Cons: Measured -3dB extension is 47.6Hz, so the larger 8351B and 8361A provide more useful low-end reach and headroom. The review found bass-output limitations at demanding levels. Its excellent ideal-subwoofer score should not be read as equivalent full-range output to those larger models.
