JBL 305P MKIII: accurate listening without compromising space

The JBL 305P MKIII is a 5-inch active studio monitor designed for home and production studios, podcast rooms, editing stations, and content creation. It brings the redesign of the 3 Series MKIII family to its most compact model, featuring a 127 mm woofer, a 25 mm soft dome tweeter, and 86 W of Class D amplification.

When reviewing a mix, editing vocals, or balancing the elements of a production, its JBL Image Control Waveguide helps maintain an accurate stereo image across a wide listening area. This allows you to work with multiple screens or share the station without being limited to a narrow listening position.

What makes the JBL 305P MKIII special?

It combines a wide listening area with adjustments that allow you to adapt its response to your workspace. The four equalization controls offer 81 combinations to compensate for monitor placement, proximity to walls, and the balance of lows and highs, without software or complex switch settings.

The redesigned woofer incorporates stiffer cone materials, a 20 oz magnet assembly, and an aluminum shorting ring to reduce distortion and increase the output level. The front Slipstream port contributes to clean, controlled lows and makes the response more predictable when placing the monitor on a desk or near a wall. The new amplifier provides a higher output level with less distortion and noise.

Its installation can be adapted to a desk, wall, high-mount, or inverted position. In addition, you can start with a stereo pair, add a JBL subwoofer, and later expand to a surround or immersive setup, taking advantage of the tonal coherence between the models in the 3 Series MKIII family.
