Short answer: the JBL 4305P for better sound quality, the Kali Audio LP-6 V2 for the lower price. The JBL 4305P ranks #14 of 40 powered bookshelf speakers at $2200. The Kali Audio LP-6 V2 ranks #17 at $398, $1802 cheaper.
What the JBL 4305P offers: Erin measured a 45Hz F3 and heard solid 40–50Hz in-room extension—excellent for a compact 5.25-inch active monitor. Watch for: The limiter becomes conspicuous around 96dB: Erin measured about 8dB lost near 50Hz at the highest drive and achieved roughly 93dB unweighted at 2m in-room.
On the Kali Audio LP-6 V2 side: Outstandingly neutral active monitor for the money, with no audible amplifier hiss in Erin’s listening and excellent horizontal directivity from the contoured waveguide. Set against that: A vertical directivity disturbance around 1.5-2kHz makes ear height important; desk or console reflections and ceiling bounce can expose the crossover lobing, so absorption may help.
Buy the JBL 4305P if sound quality matters more than the price. Buy the Kali Audio LP-6 V2 if the price matters more than sound quality.

JBL 4305P: $2,200/pair Amazon JBL
Pros: Erin measured a 45Hz F3 and heard solid 40–50Hz in-room extension—excellent for a compact 5.25-inch active monitor. Tonality is neutral and non-fatiguing, vocal coloration is absent, imaging is precise, and the HDI horn maintains near-constant horizontal directivity above 2kHz. Each speaker is bi-amplified (125W LF + 25W HF), while USB, optical, balanced analog, AirPlay 2, Chromecast, Bluetooth and 24/192 wired interconnect make this an unusually complete system. Grilles caused no meaningful response penalty.
Cons: The limiter becomes conspicuous around 96dB: Erin measured about 8dB lost near 50Hz at the highest drive and achieved roughly 93dB unweighted at 2m in-room, so this is a near/midfield system rather than a high-output theater speaker. A baffle discontinuity produces a 1–2kHz directivity mismatch that cannot be corrected uniformly in the vertical plane; stay within about +/-5° of tweeter height. Soundstage depth and layering trailed the KEF Reference 1 Meta, and wireless speaker linking caps resolution at 24/96.

Kali Audio LP-6 V2: $398/pair Amazon Sweetwater
Pros: Outstandingly neutral active monitor for the money, with no audible amplifier hiss in Erin’s listening and excellent horizontal directivity from the contoured waveguide. Erin measured 42Hz F3 and on-axis linearity within approximately -2.51/+1.99dB. The pair remains respectably linear to roughly 102dB at 1m, the front port controls turbulence, and rear DIP switches provide practical boundary-placement profiles plus LF/HF trims. Balanced XLR/TRS and unbalanced RCA inputs broaden compatibility; Erin needed only about +1.5dB near 8kHz for his preferred amount of air.
Cons: A vertical directivity disturbance around 1.5-2kHz makes ear height important; desk or console reflections and ceiling bounce can expose the crossover lobing, so absorption may help. Limiting becomes visible above 96dB/1m, and from 76 to 96dB the low-frequency/midband balance drops by roughly 1dB, making this better as a nearfield or modest-distance monitor than a far-field high-output system. There is no digital input or network control, and each speaker needs AC power and a separate signal cable.
