What customers say
Customers overwhelmingly praise the JBL 308P MkII for its exceptional value and sound quality, positioning it as a leading choice in affordable professional monitoring. The core theme is outstanding clarity, driven by the Image Control Waveguide, which creates a remarkably wide and forgiving sweet spot. Users consistently highlight the powerful 8-inch woofer for delivering deep, articulate bass that maintains midrange accuracy.

Know before you buy
Yes, they work well in home studios, though their 8-inch woofer provides a significant soundstage that is best suited for medium-to-large rooms. If your workspace is very tight, ensure you have enough desk or stand space to accommodate their 16.5-inch height.
No, the JBL 308P MkII is a powered monitor, meaning it has built-in Class D amplifiers. You only need to connect your audio source via XLR or TRS cables and plug the speakers into a power outlet.
These controls allow you to adjust the speaker's output to compensate for your room's acoustics. The Boundary EQ helps reduce bass buildup if the speakers are placed near walls, while the HF Trim lets you adjust the high-frequency response to suit the brightness of your specific environment.
Yes, these speakers are magnetically shielded, which prevents them from causing interference with sensitive electronic equipment placed nearby.
You can use either balanced XLR or 1/4-inch TRS cables. Since these inputs are balanced, they are excellent for minimizing noise and interference in your signal chain.
This wide coverage pattern creates a larger 'sweet spot,' meaning you don't have to be perfectly centered between the speakers to hear an accurate, balanced mix. It makes the monitors more forgiving and versatile for different listening positions.
