#40 JBL 306P MKII: $398 B&H Photo Video eBay

Pros: A 6.02 ideal-subwoofer score and 46.9Hz measured -3dB extension make this a useful affordable nearfield monitor. The waveguide supports broad horizontal listening coverage, and basic boundary controls help with setup.

Cons: The 3.4dB response span from 300Hz to 5kHz is less even than the 308P MKII’s, with midrange resonances affecting neutrality. Hiss can matter at a quiet desk, while bass distortion limits demanding playback. A subwoofer improves bandwidth but does not remove the midrange irregularities.

How it compares: Just above it: Klipsch The Nines - $602 more, 128W more output power. Just below it: Sigberg Audio Manta - $31822 more, 488W more output power.
