For over 75 years, JBL has championed innovation in audio, delivering high-end sound solutions that have been trusted by professionals in music, film and broadcast. In this spirit, the 305P MKII studio monitors make professional-grade technology accessible to anyone, whether you’re making music, podcasting or creating content in a home studio.
At the heart of the 305P MKII is a handful of cutting-edge technologies that can also be found in JBL's premium models, like the flagship M2 Master Reference Monitors. A standout feature of the M2 and the 305P MKII is the patented Image Control Waveguide, which helps to achieve precise imaging, stunning detail, and a broad sweet spot, making it even easier to produce accurate mixes across diverse environments.
JBL's advanced, class-leading transducers lie behind the 305P MKII’s superior sound. A 1-inch neodymium tweeter is responsible for its crisp and detailed highs, while a 5-inch woofer provides deep but controlled bass - thanks to JBL’s patented Slip Stream™ low-frequency port.
This helps the 305P deliver an exceptional frequency response, whether you're involved in music production, sound design, or podcasting. With Class-D amplifiers custom-engineered for each transducer, the 305P MKII boasts impressive dynamic range and power right out of the box, making it an ideal choice for demanding projects.
What’s more, the 305P MKII is equipped with an array of features to adapt to your specific choice of studio space. Boundary EQ settings allow for low-end adjustment when monitors are placed near walls or on a desktop, while a 3-position HF Trim switch can tailor high frequencies to match room acoustics or personal preferences, producing optimal sound in any studio environment.
JBL’s commitment to reliability is built into every product, and the 305P MKII is no exception. Every unit goes through JBL’s famed 100-Hour Torture Test, a rigorous evaluation that ensures the monitor performs flawlessly at full power for over four days.
This industry-leading test simulates the most demanding conditions, ensuring that the 305P MKII monitors deliver consistent sound quality over many years of use. This testing process, coupled with JBL's anechoic chamber testing and Speaker Shuffler system for accurate A/B comparisons, guarantees that every monitor is fine-tuned for high performance and longevity.
JBL’s Linear Spatial Reference (LSR) design ensures a consistently neutral sound by measuring the speaker’s performance in a full 360-degree field during testing. Unlike conventional methods, based on limited on-axis measurements, this approach allows for better stereo imaging, a broader sweet spot, and a smoother off-axis response, ensuring your audio is always accurately represented, no matter where you’re hearing it from.
Delivering professional sound at an accessible price point, the 305P MKII is a great choice for both enthusiasts and professionals. At just under £250 per pair, these monitors offer outstanding value while giving customers access to advanced technologies found in JBL’s high-end products.
