Short answer: the Adam Audio S2V. It ranks #13 of 66 powered bookshelf speakers by sound quality; the LOGProfessional Alpha ranks #14.
What the LOGProfessional Alpha offers: Sound & Recording’s measurements show a 1.2dB response span from 300Hz to 5kHz and a 7.36 ideal-subwoofer score. This supports a particularly even midrange and makes the Alpha a promising choice for a system with properly integrated bass support. Watch for: The measured -3dB point is 67.1Hz, making a subwoofer important for full-range listening. A smooth midrange is not proof of high clean output or uniformly controlled dispersion.
What the Adam Audio S2V offers: A 7.22 ideal-subwoofer score and relatively even listening-window response support a strong role as a subwoofer-assisted studio monitor. The review’s low-distortion findings add useful evidence beyond amplifier ratings, and onboard DSP permits tailored adjustment. Watch for: Measured -3dB extension is 52.7Hz, so the large cabinet does not automatically deliver the deepest bass here. The native balance rises toward the treble, with some lower-midrange unevenness. DSP can improve that balance, but an EQ-optimized result is not its unadjusted performance.
Buy the LOGProfessional Alpha if the price matters more than sound quality. Buy the Adam Audio S2V if sound quality matters more than the price.
