Short answer: both are discontinued, so this only matters if you are buying used. Used, the KRK Rokit 8 G4 is the better pick: it ranks #66 of 79 powered bookshelf speakers by sound quality (rated 3.9/5), against #46 (rated 3.7/5) for the KRK Rokit 5 G4. If you want one new, the JBL 308P MKII ranks #26 at $298.
Why pick the KRK Rokit 8 G4: An 8-inch active monitor with balanced studio connections and room-adjustment controls, offering a practical basis for a desktop or small studio system. The catch: The large cabinet requires substantial desk or stand space.
The case for the KRK Rokit 5 G4: ASR’s data gives -3dB bass around 56Hz and scores of 3.92 standalone and 6.29 with an ideal subwoofer. The catch: The 3.6dB midrange span and listening-window narrow-band deviation of 0.502 show that native response is not reference-flat.
Buy the KRK Rokit 8 G4 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the JBL 308P MKII instead.

Newer model: the KRK Rokit 8 G5, ranked higher, estimated 4/5.
Smaller models: the KRK Rokit 7 G4 (ranked lower, rated 3.9/5) and the KRK Rokit 5 G4 (rated 3.7/5).
Pros: An 8-inch active monitor with balanced studio connections and room-adjustment controls, offering a practical basis for a desktop or small studio system. The larger format may suit listeners who want more scale than a compact monitor.
Cons: The large cabinet requires substantial desk or stand space. Its balanced studio inputs need a suitable source connection rather than offering built-in consumer streaming. Discontinued.

KRK Rokit 5 G4: $337 per pair Discontinued eBay
Newer model: the KRK Rokit 5 G5, ranked higher, estimated 3.8/5.
Larger models: the KRK Rokit 7 G4 (rated 3.9/5) and the KRK Rokit 8 G4 (rated 3.9/5).
Pros: ASR’s data gives -3dB bass around 56Hz and scores of 3.92 standalone and 6.29 with an ideal subwoofer. The waveguide provides useful horizontal directivity control, while onboard adjustments help tailor broad balance. The existing review reports low distortion at 86dB and low audible hiss. Measured bass extension of 55.7Hz (-3dB).
Cons: The 3.6dB midrange span and listening-window narrow-band deviation of 0.502 show that native response is not reference-flat. A port-region resonance and other tonal irregularities remain. Its deeper bass does not establish greater detail or mixing accuracy than another monitor. EQ can help, but the unequalized measurements determine the starting recommendation. Discontinued.
