Short answer: the Kali Audio LP-6 V2, if you are buying new. The Buchardt A500 ranks higher than it (#18 vs #37 of 113 powered bookshelf speakers, 4.6/5 vs 4.4/5) but is discontinued, so only consider it used; the Kali Audio LP-6 V2 is still sold new at $498.
Why pick the Kali Audio LP-6 V2: Erin’s measurements give a 7.48 ideal-subwoofer score and 42.5Hz -3dB bass extension, a strong combination for an affordable nearfield monitor. Watch for: The 2.5dB response span from 300Hz to 5kHz leaves some tonal unevenness.
The Buchardt A500 is the more accurate, deeper-bass option. Erin measured unusually deep bass for the cabinet size: 24.9Hz at -3dB. Its measured preference score, a predictor of how neutral it sounds, is 7.02 against 5.53 for the Kali Audio LP-6 V2. Its bass reaches about 24.9Hz before falling 3dB, against 42Hz for the Kali Audio LP-6 V2. The catch: Bass extension depends on the selected tuning and comes with output tradeoffs at high levels.
Buy the Kali Audio LP-6 V2 if you want one new; the Buchardt A500 is discontinued, so only look for it used.

Kali Audio LP-6 V2: $498 per pair B&H Photo Video eBay
Older model: the Kali Audio LP-6 (ranked lower, rated 4.3/5).
Same family: the Kali Audio LP-8 V2 (larger bookshelf, ranked lower, rated 4.1/5) and the Kali LP-UNF (larger bookshelf, rated 3.9/5).
Pros: Erin’s measurements give a 7.48 ideal-subwoofer score and 42.5Hz -3dB bass extension, a strong combination for an affordable nearfield monitor. The waveguide and placement switches help with practical setup, and the second generation improves close-range noise behavior. Measured bass extension of 42Hz (-3dB).
Cons: The 2.5dB response span from 300Hz to 5kHz leaves some tonal unevenness. Vertical crossover behavior makes ear-height placement important, and compression limits loud bass playback. Its good tonal score is not evidence of the output capability of a much larger monitor.

Buchardt A500: $4,150 per pair Discontinued Buchardt Audio eBay
Same family: the Buchardt A10 (smaller bookshelf, ranked higher, rated 4.7/5) and the Buchardt A700 (floorstanding, rated 4.5/5).
Pros: Erin measured unusually deep bass for the cabinet size: 24.9Hz at -3dB. A 1.8dB response span from 300Hz to 5kHz and 7.02 standalone preference score support balanced, full-range listening. Master Tunings and optional wireless integration provide practical flexibility. Measured bass extension of 24.9Hz (-3dB).
Cons: Bass extension depends on the selected tuning and comes with output tradeoffs at high levels. The 7.92 ideal-subwoofer score is good but not class-leading. A rear-facing woofer does not by itself establish cardioid radiation, and alternate Master Tunings should not inherit the measured configuration’s score. Discontinued.
