Short answer: the HEDD Type 20 MK2 if sound quality matters most, the JBL 4305P if price matters most. The HEDD Type 20 MK2 ranks #18 of 66 powered bookshelf speakers at $4800. The JBL 4305P ranks #28 at $2200, $2600 cheaper.
What the HEDD Type 20 MK2 offers: CEA2034 spinorama shows a nice flat on-axis response with a very smooth directivity index, plus an intentional boost at 40-50Hz for extra bass warmth. Watch for: Horizontal beamwidth is asymmetric (+60/-80 degrees depending on reference point) and narrows above 10kHz.
What the JBL 4305P offers: Erin measured a 45Hz F3 and heard solid 40–50Hz in-room extension—excellent for a compact 5.25-inch active monitor. Watch for: 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, so this is a near/midfield system rather than a high-output theater…
Buy the HEDD Type 20 MK2 if sound quality matters more than the price. Buy the JBL 4305P if the price matters more than sound quality.

HEDD Type 20 MK2: $4800 B&H Photo Video eBay
Pros: The measured ported configuration reaches 35.2Hz at -3dB and scores 6.92 with an ideal subwoofer. A 2.4dB response span from 300Hz to 5kHz supports broadly balanced mids, while ported operation reduces deep-bass strain compared with the sealed setting in the review.
Cons: These results are for ported operation, not every bass or phase setting. Horizontal asymmetry and vertical crossover behavior make orientation and listening position important. Distortion rises at higher output, and linear-phase processing can add latency for live monitoring.

JBL 4305P: $2,200/pair Amazon JBL eBay
Pros: The measured 1.5dB response span from 300Hz to 5kHz supports even mids, with a 6.54 ideal-subwoofer score and 45.4Hz -3dB bass extension. Integrated consumer connectivity makes this a more convenient living-room system than many studio monitors.
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.
