Genelec 8361A vs JBL 308P 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 5.88 for the JBL 308P MKII. Its bass reaches about 34Hz before falling 3dB, against 42.5Hz for the JBL 308P MKII. It has an adjustable EQ, which the JBL 308P MKII lacks. The tradeoff: Its larger size buys headroom, not uniformly better tonality than the smaller Ones models.

Why pick the JBL 308P MKII: A 1.8dB response span from 300Hz to 5kHz and 7.69 ideal-subwoofer score support unusually good tonal balance for an accessible studio monitor. The catch: Amplifier hiss may be noticeable in quiet, close-range use.

Buy the Genelec 8361A if sound quality matters more than the price. Buy the JBL 308P MKII if the price matters more than sound quality.

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 308P MKII ranking card

Older model: the JBL LSR308 (ranked lower, estimated 4.2/5).

Same family: the JBL 305P MKII (smaller bookshelf, rated 4.3/5) and the JBL 306P MKII (smaller bookshelf, ranked lower, rated 4.1/5).

Pros: A 1.8dB response span from 300Hz to 5kHz and 7.69 ideal-subwoofer score support unusually good tonal balance for an accessible studio monitor. Measured -3dB extension of 42.5Hz supplies useful musical bass, and the waveguide helps maintain consistent horizontal coverage. Measured bass extension of 42.5Hz (-3dB).

Cons: Amplifier hiss may be noticeable in quiet, close-range use. Bass distortion and output limits matter when playing loudly, despite the 8-inch woofer. Keep the tweeter near ear height; vertical crossover behavior is less forgiving than the best coaxial designs. A resonance around 18kHz and a slight dip around 1.4kHz.
