Short answer: the Adam Audio S2V. Both are rated 4.6/5 for sound quality (#16 and #20 of 113 powered bookshelf speakers), and the Adam Audio S2V costs $3,399.98 against $4,998 for the Neumann KH 310 A, and with sound quality even, the cheaper one is the better buy.
The Neumann KH 310 A is the deeper-bass pick. The sealed three-way design combines 35.2Hz measured -3dB extension with low distortion in the review’s demanding playback tests. Its bass reaches about 35.2Hz before falling 3dB, against 52.7Hz for the Adam Audio S2V. The catch: Its measured tonal balance is not as even as the Neumann KH 150 or the best coaxial alternatives.
The case for the Adam Audio S2V: A 7.98 ideal-subwoofer score and relatively even listening-window response support a strong role as a subwoofer-assisted studio monitor. Watch for: Measured -3dB extension is 52.7Hz, so the large cabinet does not automatically deliver the deepest bass here.
Buy the Adam Audio S2V. Both are rated the same for sound quality, and it costs $1,598.02 less than the Neumann KH 310 A.

Neumann KH 310 A: $4,998 per pair B&H Photo Video eBay
Same family: the Neumann KH80 DSP (smaller bookshelf, rated 4.6/5), the Neumann KH120 MKII (smaller bookshelf, rated 4.7/5), the Neumann KH 150 (smaller bookshelf, ranked higher, rated 4.8/5), the Neumann KH420 (larger bookshelf, ranked higher, rated 4.8/5) and the Neumann KH 750 DSP (subwoofer, rated 3.5/5).
Pros: The sealed three-way design combines 35.2Hz measured -3dB extension with low distortion in the review’s demanding playback tests. Its 2.2dB response span from 300Hz to 5kHz and 7.70 ideal-subwoofer score support balanced monitoring with useful full-range capability. Measured bass extension of 35.2Hz (-3dB).
Cons: Its measured tonal balance is not as even as the Neumann KH 150 or the best coaxial alternatives. Correct orientation and listening height matter for the separated drivers. The analog system lacks the integrated calibration workflow of newer DSP models, so room correction requires additional equipment. An unexplained dip around 80Hz shows in the measurements.

Adam Audio S2V: $3,399.98 per pair Amazon eBay
Same family: the ADAM Audio S3V (larger bookshelf, ranked lower, estimated 4.5/5), the ADAM Audio S3H (larger bookshelf, ranked lower, estimated 4.5/5), the ADAM Audio S5V (larger bookshelf, ranked lower, estimated 4.4/5) and the ADAM Audio S5H (larger bookshelf, ranked lower, estimated 4.4/5).
Pros: A 7.98 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. The review measured distortion about 70dB below the signal at 1kHz. Measured bass extension of 52.7Hz (-3dB).
Cons: 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.
