Genelec 8361A vs JBL 306P MKII

Last updated: October 9, 2026

Short answer: the Genelec 8361A for better sound quality, the JBL 306P MKII for the lower price. The Genelec 8361A ranks #6 of 113 powered bookshelf speakers, rated 4.8/5, at $11,700. The JBL 306P MKII ranks #67, rated 4.1/5, at $238, $11,462 cheaper.

Genelec 8361A vs JBL 306P MKII

The Genelec 8361A is the more accurate, deeper-bass option. The coaxial design combines consistent imaging with substantial output capability. Its measured preference score, a predictor of how neutral it sounds, is 6.76 against 5.06 for the JBL 306P MKII. Its bass reaches about 34Hz before falling 3dB, against 46.9Hz for the JBL 306P MKII. It has an adjustable EQ, which the JBL 306P MKII lacks. The tradeoff: Its larger size buys headroom, not uniformly better tonality than the smaller Ones models.

What the JBL 306P MKII does well: A 6.94 ideal-subwoofer score and 46.9Hz measured -3dB extension make this a useful affordable nearfield monitor. The catch: The 3.4dB response span from 300Hz to 5kHz is less even than the JBL 308P MKII’s, with midrange resonances affecting neutrality.

Buy the Genelec 8361A when sound quality outweighs the price for you, and the JBL 306P MKII when the price outweighs sound quality instead.

Genelec 8361A ranking card

Same family: the Genelec 8331A (smaller bookshelf, rated 4.8/5), the Genelec 8341A (smaller bookshelf, ranked lower, rated 4.8/5), the Genelec 8351B (smaller bookshelf, ranked higher, rated 4.8/5) and the Genelec 8381A (floorstanding, estimated 4.9/5).

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 306P MKII ranking card

Same family: the JBL 305P MKII (smaller bookshelf, rated 4.3/5) and the JBL 308P MKII (larger bookshelf, ranked higher, rated 4.4/5).

Pros: A 6.94 ideal-subwoofer score and 46.9Hz measured -3dB extension make this a useful affordable nearfield monitor. The waveguide supports broad horizontal listening coverage, and basic boundary controls help with setup. Measured bass extension of 46.9Hz (-3dB).

Cons: The 3.4dB response span from 300Hz to 5kHz is less even than the JBL 308P MKII’s, with midrange resonances affecting neutrality. Hiss can matter at a quiet desk, while bass distortion limits demanding playback. A subwoofer improves bandwidth but does not remove the midrange irregularities. A narrow dip around 1.6kHz shows in the on-axis and listening-window curves.
