Short answer: the JBL 705P if sound quality matters most, the Audioengine HD4 if price matters most. The JBL 705P ranks #42 of 100 powered bookshelf speakers, rated 3.9/5, at $2,198. The Audioengine HD4 ranks #83, rated 3.2/5, at $429, $1,769 cheaper.
The JBL 705P is the better-sounding choice. ASR’s data gives bass reaching -3dB around 48Hz and a 6.71 ideal-subwoofer preference score. Watch for: The standalone score is 4.70, and a localized cancellation near 750Hz contributes to the large 7.8dB midrange response span.
What the Audioengine HD4 does well: Compact powered cabinets, analog input options and RCA output can simplify a desktop stereo system. It keeps a wired aux input, which the JBL 705P lacks. The tradeoff: The compact cabinets suit close desktop listening rather than a large-room system.
Buy the JBL 705P if sound quality is the priority over the price, or the Audioengine HD4 if the price is the priority over sound quality.

The Two Speakers In Full
JBL 705P: $2,198 per pair B&H Photo Video eBay
Same family: the JBL 708P (larger bookshelf, rated 4.2/5).
Pros: ASR’s data gives bass reaching -3dB around 48Hz and a 6.71 ideal-subwoofer preference score. Its waveguided compression driver and dedicated amplification are suited to studio use, and the broad response trend is close to level. It has useful low-frequency reach for a five-inch monitor. Measured bass extension of 47.6Hz (-3dB).
Cons: The standalone score is 4.70, and a localized cancellation near 750Hz contributes to the large 7.8dB midrange response span. A crossover-region rise also prevents reference-flat reproduction. An average flat trend does not erase these features, and amplifier wattage is not a measured clean-SPL rating. The data does not support calling it uniformly flat simply because it shares technology with larger JBL models.

Audioengine HD4: $429.00 per pair Amazon eBay
Same family: the Audioengine HD3 (smaller bookshelf, rated 3.2/5) and the Audioengine HD6 (larger bookshelf, ranked higher, rated 3.3/5).
Pros: Compact powered cabinets, analog input options and RCA output can simplify a desktop stereo system. Its modest footprint is useful where larger studio monitors are impractical.
Cons: The compact cabinets suit close desktop listening rather than a large-room system. A separate subwoofer adds cost and space if deeper bass is a priority.
