⭐⭐⭐⭐☆ (9.0/10)
Sound Quality
For a compact 5-inch monitor, the 305P MkII delivers clear mids, smooth highs, and a surprisingly tight low end that extends down to around 49 Hz. The low frequencies are controlled rather than boomy, which keeps mixes from becoming muddy.
The Image Control Waveguide provides excellent stereo imaging and a wide sweet spot, so you don’t need to stay locked in one position to hear your mix accurately. While it won’t replace larger 8-inch monitors for sub-heavy genres, the sound quality punches far above its price.
Build & Design
The JBL 305P MkII features a sleek black cabinet with a front-firing waveguide design. The build feels sturdy for its size, and the design minimizes unwanted resonances.
On the back, you get balanced XLR and TRS inputs, along with EQ trim switches for high-frequency and boundary adjustments. This makes it easier to adapt the speakers to your room setup.
Features
- 5-inch powered two-way design with 41W LF and 41W HF Class-D amplifiers

- Frequency response: 49 Hz – 20 kHz (±3 dB)

Price & Value

While you may want an 8-inch model or a sub for deeper bass, the 305P MkII offers incredible value and performance for its size and price.
Rating: 9.0/10 — One of the best budget studio monitors available, combining precision and affordability for serious home producers.
