Short answer: the JBL 4329P. It ranks #21 of 61 powered bookshelf speakers by sound quality at $4500; the Genelec 8341A ranks #42 and costs $6590, so there is not much of a tradeoff to weigh.
What the JBL 4329P offers: 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. Watch for: 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.
What the Genelec 8341A offers: CEA2034 spinorama shows an exceptionally flat on-axis response, within about +1.8dB/-2.2dB of the target curve, with excellent directivity control from the coaxial midrange/tweeter and dual 6.5” woofers. Tri-amplified design totals 550W across bass, mid, and treble sections. Watch for: The bass amplifier runs out of headroom well before the mid/treble sections, producing audible glitching/ticking distortion at higher volumes even at 1 meter - not well suited to larger rooms or higher playback levels as a result. No hard power switch, and it produces a loud static pop when AC power is cut. Very expensive at $6,590 per pair.
Buy the JBL 4329P. It ranks higher for sound quality than the Genelec 8341A and costs less, so there is no real case for the other one.
