Active studio monitor JBL 308P MKII — 8-inch powered reference monitor, bi-amplified nearfield speaker

The JBL 308P MKII is an active 8-inch studio monitor engineered for nearfield reference listening and mixing. As a bi-amplified powered speaker with a dedicated woofer and tweeter, it offers a balanced frequency response and clear stereo imaging for monitoring tasks. The monitor includes room-tuning controls and balanced input options to integrate with professional and home studio setups, delivering dependable low-frequency response and accurate midrange detail for production and mixing work.

Advantages

The bi-amplified design separates low and high frequency amplification to reduce intermodulation and improve clarity. The 8-inch woofer provides extended low-frequency performance suitable for accurate monitoring of bass content, while the precise tweeter reproduces high-frequency detail with low distortion. Room-tuning controls allow adjustment for placement near walls or in small rooms, helping to maintain a neutral response. Balanced inputs ensure reliable connection to audio interfaces and mixing consoles, minimizing hum and interference.

Suitable for

• Nearfield monitoring in home and project studios
• Mixing and audio production for music, podcasts, and media
• Reference listening for sound design and editing
• Multimedia workstations and small control rooms

Key specifications

• Driver configuration: 8-inch woofer and high-frequency driver
• Amplification: Bi-amplified active design with dedicated LF and HF amps
• Frequency balance: Tunable response with room-control options
• Inputs: Balanced audio inputs for professional connectivity
• Enclosure: Designed for nearfield placement with optimized porting

How to use

Place the monitor at nearfield listening distance, forming an equilateral triangle between the two monitors and the listener for accurate stereo imaging. Connect the balanced outputs of your audio interface or mixer to the monitor’s balanced inputs using appropriate cables. Use the room-tuning controls to compensate for boundary placement or room acoustics; start with flat settings and adjust gradually while listening to familiar reference material. Allow a short warm-up period after powering on for consistent performance.

Usage recommendations

Position the monitors at ear level and use isolation pads or stands to reduce cabinet vibration and room coupling. For reliable results in mixing and production, check mixes on multiple systems and use the JBL 308P MKII as a neutral nearfield reference to evaluate balance, clarity, and bass response.
