Short answer: the Adam Audio A4V for better sound quality, the Audioengine HD4 for the lower price. The Adam Audio A4V ranks #43 of 67 powered bookshelf speakers, rated 3.6/5, at $1,199.98. The Audioengine HD4 ranks #58, rated 3.2/5, at $429, $770.98 cheaper.
Why pick the Adam Audio A4V: Compact monitor with onboard DSP, placement controls and room-correction integration. The catch: A small average-deviation figure hides a major localized response irregularity: the selected measurement spans 10.8dB from 300Hz to 5kHz, and listening-window narrow-band deviation is 0.547.
What the Audioengine HD4 does well: Compact powered cabinets, analog input options and RCA output can simplify a desktop stereo system. Watch for: The compact cabinets suit close desktop listening rather than a large-room system.
Buy the Adam Audio A4V if sound quality is the priority over the price, or the Audioengine HD4 if the price is the priority over sound quality.

Adam Audio A4V: $1,199.98 per pair B&H Photo Video eBay
Pros: Compact monitor with onboard DSP, placement controls and room-correction integration. ASR’s Klippel data gives a -3dB point around 59Hz and preference scores of 3.92 standalone and 6.33 with an ideal subwoofer. Its adjustment facilities are useful when placement or tonal correction is needed.
Cons: A small average-deviation figure hides a major localized response irregularity: the selected measurement spans 10.8dB from 300Hz to 5kHz, and listening-window narrow-band deviation is 0.547. The native response should therefore not be called smoothly neutral. Correction potential is not the same as stock performance, and analog audio inputs mean a separate interface is needed for USB sources.

Audioengine HD4: $429.00 per pair Amazon eBay
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.
