Short answer: the JBL 4329P for better sound quality, the Adam Audio T7V for the lower price. The JBL 4329P ranks #19 of 40 powered bookshelf speakers at $4500. The Adam Audio T7V ranks #26 at $289.99, $4210.01 cheaper.
The case for the JBL 4329P: Genuinely full-range performance for a bookshelf-style speaker - anechoic response extends to 30Hz (measured F3 31Hz), reaching into the low 20s Hz range in-room depending on placement. The tradeoff: No HDMI input, a real drawback if you want to run these directly off a TV’s ARC.
What the Adam Audio T7V offers: Quite balanced and neutral, very close to the Yamaha HS8. Watch for: 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 4329P if sound quality matters more than the price. Buy the Adam Audio T7V if the price matters more than sound quality.

The Two Speakers In Full
JBL 4329P: $4,500 Amazon
Pros: Genuinely full-range performance for a bookshelf-style speaker - anechoic response extends to 30Hz (measured F3 31Hz), reaching into the low 20s Hz range in-room depending on placement, with strong bass authority rather than a rolled-off, thin low end. Wide, constant horizontal directivity through the midrange and into the treble (about ±60°, wider than most horn-loaded designs which tend to run closer to ±40°) gives a wide, stable stereo image without needing to toe the speakers out and lose top-end energy. The reviewer listened for an hour-long sessions repeatedly without listener fatigue, across two very different rooms, with consistently great results in both. Extensive connectivity: USB, Optical, Bluetooth, analog, 3.5mm, AirPlay 2, and 24-bit/192kHz support; comes with a remote.
Cons: No HDMI input, a real drawback if you want to run these directly off a TV’s ARC. The supplied ethernet link cable between the two speakers is short - workable at close range but not long enough for wider speaker placement, so budget for a longer aftermarket cable if your setup needs it. A dip around 900Hz shows up in the on-axis measurement that the reviewer couldn’t fully explain (ruled out the ports as the cause, suspects cabinet edge diffraction), though it wasn’t something that bothered him in listening. At $4,500/pair, this is a serious investment for a bookshelf-format speaker.

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.
