Genelec 8361A vs JBL 708P

Last updated: October 1, 2026

Short answer: the Genelec 8361A for consistent vertical response, the JBL 708P for horizontal directivity. The 8361A’s three-way coaxial layout gives nearly identical vertical response whether you sit or stand, but it costs about $10,900 and GLM is extra. The 708P measures extremely well with excellent horizontal directivity, though a port resonance lifts 600-900Hz and its vertical dispersion is narrower, so stay near the tweeter axis.

Genelec 8361A vs JBL 708P

What the Genelec 8361A offers: 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. Set against that: $10,900 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 708P side: CEA2034 spinorama shows extremely good frequency response both on- and off-axis, with excellent horizontal directivity. The tradeoff: A port resonance creates a mild rise around 600-900Hz. Vertical dispersion is narrower than horizontal, so staying within a few degrees of the tweeter axis matters.

Buy the Genelec 8361A when sound quality outweighs the price for you, and the JBL 708P when the price outweighs sound quality instead.

Pros: The coaxial design combines consistent imaging with substantial output capability. ASR measured a 1.8dB response span from 300Hz to 5kHz, 33.7Hz -3dB extension and a 8.08 ideal-subwoofer score. Low distortion and restrained compression support its use at greater distances than smaller nearfield monitors. Woofers above and below the coaxial driver give nearly identical vertical response whether you sit or stand. Measured bass extension of 34Hz (-3dB).

Cons: Its larger size buys headroom, not uniformly better tonality than the smaller Ones models. Some lower-midrange unevenness remains, and listening angle can affect perceived treble balance. The cabinets are very heavy and expensive; GLM setup and suitable stands need to be budgeted separately.

JBL 708P ranking card

Pros: Erin’s measurements give 43.9Hz -3dB extension and a 6.91 ideal-subwoofer score, with useful bass from a professional active monitor. The waveguide and onboard processing make it a practical choice for a carefully installed studio system. Measured bass extension of 43.9Hz (-3dB).

Cons: The 2.6dB response span from 300Hz to 5kHz includes audible-relevance irregularities, with port-region features and vertical crossover sensitivity. High-level distortion remains a constraint. Its professional positioning and amplifier power do not make it automatically more neutral than the cheaper 308P MKII. A port resonance adds a mild rise around 600 to 900Hz, and vertical dispersion is narrower than horizontal, so stay within a few degrees of the tweeter axis.
