JBL 305P MKII

JBL 305P MKII | 5-inch Active Near-Field Studio Monitor Pair

Active studio monitors built for mixing, editing, and content production

The JBL 305P MKII is an active studio monitor from JBL, featuring proprietary Image Control Waveguide technology and a dual-amplifier Class D design. With 82W amplifier power, 49Hz–20kHz frequency response, and up to 108 dB maximum sound pressure (SPL), it is designed for near-field monitoring, mixing decisions, and desktop studio applications.

Compared with traditional home speakers or ordinary computer speakers, the JBL 305P MKII uses the linear response, wide sweet spot, and balanced input design required of a studio monitor to deliver more accurate spatial imaging and frequency-band judgment. Compared with other entry-level near-field systems in its class, its Image Control Waveguide, Slip Stream bass port, and room compensation features offer advantages for real-world use in small studios, making it especially suitable for creators who need studio monitoring, mixing speakers, and audio/video post-production.

Who is the JBL 305P MKII for?

使用者建議分析(點此展開)

▼

適合誰購買

Home studio creators who want to upgrade their monitoring system and need more accurate frequency judgment and stereo imaging than computer speakers can provide
Music producers who work at a desktop near-field setup for long periods and want clear imaging and a stable sweet spot in limited space
Video editors and content creators who need to balance dialogue, music, and sound effects details without distortion or coloration when outputting to other devices
Beginners setting up a personal studio who want to buy a pair of active studio monitors directly and reduce the complexity of external amplifier configuration

誰不適合購買

People who mainly want high-SPL entertainment listening in a large living room and are chasing theater-like bass impact; their needs differ from near-field monitoring
Users who already have a professional monitoring system at or above this level and only want a minor upgrade; the return on duplicate investment may be limited
People who only want to play music wirelessly from a phone via Bluetooth and do not plan to connect an audio interface or mixer; this use case does not match well

JBL 305P MKII core technologies and features

Image Control Waveguide technology：Inheriting the design philosophy of JBL 7 Series and M2 Master Reference Monitor, it provides clearer left-right positioning, depth layering, and a wider sweet spot, allowing users to maintain stable judgment without being locked to a single listening position.
New-generation driver design：Uses next-generation JBL drivers optimized for transient response and linear performance, making it easier to distinguish details such as drum attack, bass contour, vocal sibilance, and room reverb.
Dual-amplifier Class D design：Each speaker has built-in LF 41W and HF 41W amplifiers, for a total output of 82W, balancing efficiency, dynamics, and control to provide sufficient sound pressure and clarity for desktop near-field and small studio use.
Slip Stream bass port：JBL’s patented dual-flared port design reduces airflow turbulence and port noise, maintaining bass readability at lower monitoring levels and reducing low-end muddiness at higher volumes.
Boundary EQ room compensation：When speakers are placed near a wall, on a desk, or in a corner, bass is often boosted by the environment; the built-in Boundary EQ corrects low-frequency anomalies caused by placement and improves flexibility in small-room setups.
HF Trim high-frequency adjustment：Adjust the high-frequency output according to room absorption, desk reflections, or personal listening preference so monitoring better matches real working conditions.
Professional balanced inputs：Provides XLR and TRS inputs for direct connection to audio interfaces, mixers, or other professional equipment; balanced transmission helps reduce noise and interference.
+4dBu / -10dBV input sensitivity switch：Compatible with both professional and consumer signal levels, improving integration with different source devices.
JBL Linear Spatial Reference design standard：Built according to JBL’s linear spatial reference standard, aiming to maintain more consistent monitoring accuracy across different acoustic environments.
100-hour reliability test：Undergoes JBL’s rigorous 100-hour power-on test to improve stability and durability for long-term work use.
Magnetic shielding and compact cabinet：Safer to place on desks, workstations, and in small studio environments, balancing space efficiency and device compatibility.

Image Control Waveguide stereo imaging technology

Inherits the waveguide design of JBL’s high-end monitoring systems, making high-frequency dispersion more even and left-right imaging plus front-to-back depth easier to identify.
The sweet spot is wider, which is especially useful for desktop work, multiple listeners, clients present, or editing situations where you frequently move position.

82W dual-amplifier power and dynamic control

Each speaker includes LF 41W and HF 41W Class D amplifiers, driving the low and high frequencies separately to improve efficiency and transient response.
During mixing, arranging, and post-production, it retains enough headroom so you can hear details and dynamic changes clearly without pushing it to the limit.

Slip Stream bass port and low-volume monitoring performance

The dual-flared port reduces airflow noise and the loose low-end character commonly found in traditional bass-reflex cabinets, keeping the bass cleaner.
Even when checking mix balance at lower volumes, the bass contour remains easier to judge, which is helpful for night work or small-room use.

Boundary EQ and HF Trim room correction features

Boundary EQ corrects low-frequency buildup caused by wall placement, corners, or desk reflections, improving common small-studio room issues.
HF Trim lets you fine-tune the amount of high frequencies according to room absorption, placement, and personal preference, making monitoring results closer to real needs.

XLR / TRS professional connectivity and input sensitivity switching

Balanced XLR and TRS analog inputs allow quick integration with audio interfaces, controllers, mixers, and professional playback devices.
With +4dBu / -10dBV switching and volume control, it can more precisely match different output-level sources and reduce level mismatch issues.

Notes to Know

This product is a pair of active studio monitors, and each speaker requires power; reserve power outlets and placement space before setting up on a desk
It uses professional balanced XLR / TRS inputs; if your source only has a 3.5mm output, you will need additional adapter and level-matching handling
The 5-inch woofer design is aimed at accurate near-field monitoring; if you need extreme low-frequency extension, consider pairing it with a subwoofer system
