Genelec 8050B vs JBL 4329P

Last updated: August 18, 2026

Short answer: the Genelec 8050B. It ranks #8 of 40 powered bookshelf speakers by sound quality at $3800; the JBL 4329P ranks #19 and costs $4500, so there is not much of a tradeoff to weigh.

What the Genelec 8050B offers: CEA2034 spinorama shows a very good on-axis response with excellent directivity. Watch for: A dip around 2kHz shows up in both the on-axis and predicted in-room measurements.

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.

Buy the Genelec 8050B. It ranks higher for sound quality than the JBL 4329P and costs less, so there is no real case for the other one.

Pros: CEA2034 spinorama shows a very good on-axis response with excellent directivity. Predicted in-room response is smooth, with only a 2kHz dip as a real issue. Horizontal beamwidth of about ±50 degrees is very smooth and well controlled. Vertical directivity is similarly even outside the 2kHz region, as long as listening position stays within about ±20 degrees of the woofer’s border. Distortion at 96dB SPL/1m is typical low-frequency behavior with the rest of the range well controlled.

Cons: A dip around 2kHz shows up in both the on-axis and predicted in-room measurements. An unexplained distortion spike appears around 10-15kHz at 96dB SPL/1m that the reviewer couldn’t identify a clear cause for. Cumulative spectral decay (waterfall) shows a port resonance lingering in the upper-bass/lower-midrange region. Very expensive.

JBL 4329P: $4,500 Amazon

JBL 4329P ranking card

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.
