Genelec 8351B vs Genelec 8361A

Short answer: the Genelec 8351B wins on measured flatness, the 8361A on size and driver count. The 8351B’s CEA2034 spinorama is exceptionally flat on and off axis, though deep bass distortion rises at 96dB SPL/1m and suffers below about 100Hz. The 8361A steps up to a three-way coaxial design with a 5” mid-range and inset 1” metal dome tweeter at approximately $10900 per pair.

What the Genelec 8351B gets right: CEA2034 spinorama shows exceptionally flat response both on- and off-axis. The tradeoff: Deep bass distortion rises substantially at higher output (96dB SPL/1m) - the reviewer notes “deep bass suffers” below about 100Hz.

On the Genelec 8361A side: Three-way coaxial design: 5” mid-range with an inset 1” metal dome tweeter. The catch: Approximately $11,000 per pair.

Buy the Genelec 8351B. It ranks higher for sound quality than the Genelec 8361A and costs less, so there is no real case for the other one.

Genelec 8351B: $9150 per pair B&H Photo Video eBay

Pros: The vertical ASR measurement scores 7.75 with an ideal subwoofer and reaches 35.2Hz at -3dB. Coaxial midrange and treble help maintain consistent sound as the listening angle changes. Low measured distortion at ordinary listening levels and GLM calibration make it a strong precision-monitoring choice. Measured bass extension of 33Hz (-3dB).

Cons: Bass distortion increases at higher playback levels, so a subwoofer remains useful for demanding material. Upper-treble distortion in the test also cautions against assuming unlimited output. Calibration hardware adds to an already expensive system, and the quoted result is for the measured vertical orientation.

Genelec 8361A: $10900 per pair B&H Photo Video eBay

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 7.35 ideal-subwoofer score. Low distortion and restrained compression support its use at greater distances than smaller nearfield monitors. 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.
