Short answer: the Genelec 8361A for scale, the JBL 4305P for compact bass extension. The 8361A’s three-way coaxial design adds two 10” front-loaded woofers and costs about $10,900, with GLM room correction a further extra. The 4305P reaches a measured 45Hz F3 and solid 40-50Hz in-room extension, but its limiter becomes conspicuous around 96dB, losing about 8dB near 50Hz at the highest drive.
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. Watch for: $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.
What the JBL 4305P gets right: Erin measured a 45Hz F3 and heard solid 40–50Hz in-room extension (excellent for a compact 5.25-inch active monitor). The catch: The limiter becomes conspicuous around 96dB: Erin measured about 8dB lost near 50Hz at the highest drive and achieved roughly 93dB unweighted at 2m in-room.

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 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 4305P: $1,499.99 per pair Amazon JBL eBay
Pros: The measured 1.5dB response span from 300Hz to 5kHz supports even mids, with a 7.45 ideal-subwoofer score and 45.4Hz -3dB bass extension. Integrated consumer connectivity makes this a more convenient living-room system than many studio monitors. Measured bass extension of 45Hz (-3dB).
Cons: Crossover-region directivity changes mean the narrow on-axis span does not describe every listening angle. Limiting becomes relevant at high output, particularly with bass-heavy music. It suits near- to midfield listening better than the largest high-output systems here. Erin measured about 8dB lost near 50Hz at the highest drive level and reached roughly 93dB unweighted at 2m in-room.
