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 68 powered bookshelf speakers, rated 4.5/5, at $4,800. The JBL 4305P ranks #28, rated 4.4/5, at $1,499.99, $3,300.01 cheaper.
Why pick the HEDD Type 20 MK2: The measured ported configuration reaches 35.2Hz at -3dB and scores 7.69 with an ideal subwoofer. The tradeoff: These results are for ported operation, not every bass or phase setting.
The case for the JBL 4305P: 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. The catch: Crossover-region directivity changes mean the narrow on-axis span does not describe every listening angle.

HEDD Type 20 MK2: $4800 per pair B&H Photo Video eBay
Pros: The measured ported configuration reaches 35.2Hz at -3dB and scores 7.69 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. Measured bass extension of 32Hz (-3dB).
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: $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.
