Genelec 8361A vs JBL 4329P

Last updated: August 18, 2026

Short answer: the Genelec 8361A for better sound quality, the JBL 4329P for the lower price. The Genelec 8361A ranks #5 of 40 powered bookshelf speakers at $10900. The JBL 4329P ranks #19 at $4500, $6400 cheaper.

What the Genelec 8361A gets right: Three-way coaxial design: 5” mid-range with an inset 1” metal dome tweeter, flanked symmetrically above and below by two 10” front-loaded woofers. The catch: Approximately $11,000 per pair; Genelec’s GLM room-correction add-on (measurement mic plus software) is another ~$450 and wasn’t used in this review.

On the JBL 4329P side: 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. Set against that: No HDMI input, a real drawback if you want to run these directly off a TV’s ARC.

Buy the Genelec 8361A if sound quality matters more than the price. Buy the JBL 4329P if the price matters more than sound quality.

Genelec 8361A ranking card

Pros: Three-way coaxial design: 5” mid-range with an inset 1” metal dome tweeter, flanked symmetrically above and below by two 10” front-loaded woofers, giving nearly identical vertical response whether you’re sitting or standing. Wide, consistent horizontal radiation of about ±60°, very forgiving for multiple seats or a home-theater row. Distortion at both 86dB and 96dB/1m stays below roughly 1%, and multitone distortion is also under about 1% - among the cleanest speakers reviewed. Long-term compression is practically non-existent, with no woofer bottoming or audible intermodulation even driven to 90dB+ at 10 feet. In-room bass extension reaches down to about 35Hz without a subwoofer. Extensive back-panel tuning (bass rolloff, bass profile, treble profile, and a desk/console compensation switch) for boundary placement.

Cons: Approximately $11,000 per pair; Genelec’s GLM room-correction add-on (measurement mic plus software) is another ~$450 and wasn’t used in this review. Shows an on-axis dip around 200Hz that may be tied to some rear-panel radiation or resonance the reviewer couldn’t fully explain. In far-field listening there’s a mild upper-midrange/lower-treble rise (roughly 2-3kHz) that only smooths out with 5-10° of toe-out or closer near-field placement. Short-term compression testing shows some tweeter limiting, though it didn’t translate to audible issues in real-world listening. At about 70 lbs, awkward to lift onto a stand alone.

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.
