Short answer: the JBL 4305P for better sound quality, the Adam Audio T7V for the lower price. The JBL 4305P ranks #14 of 40 powered bookshelf speakers at $2200. The Adam Audio T7V ranks #26 at $289.99, $1910.01 cheaper.
On the JBL 4305P side: Erin measured a 45Hz F3 and heard solid 40–50Hz in-room extension—excellent for a compact 5.25-inch active monitor. Set against that: 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.
What the Adam Audio T7V gets right: Quite balanced and neutral, very close to the Yamaha HS8. The catch: On-axis response is a bit wider than ideal for a nearfield monitor, and narrow vertical dispersion means you need to sit at tweeter height to get the intended tonal balance, per Audioholics’ measurements.
Buy the JBL 4305P if sound quality matters more than the price. Buy the Adam Audio T7V 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.

Adam Audio T7V: $289.99 Amazon
Pros: Quite balanced and neutral, very close to the Yamaha HS8. Deeper bass than the HS8
Cons: On-axis response is a bit wider than ideal for a nearfield monitor, and narrow vertical dispersion means you need to sit at tweeter height to get the intended tonal balance, per Audioholics’ measurements. Frequency response below 1kHz also looks a bit ragged in the digitized ASR analysis - not as smooth out of the box as some rivals, though it’s said to respond well to EQ.
