JBL LSR306P MK3 Active Studio Monitor

JBL LSR306P MK3 — Near-Field Studio Monitor with Reference Imaging

The JBL LSR306P MK3 is a 6.5-inch powered two-way studio monitor built for accurate near-field mixing in project studios and home recording spaces. It carries forward the celebrated 3 Series formula with refined transducers, a patented Image Control Waveguide and bi-amplified Class D power. Covering 43 Hz to 38 kHz with 112 dB peak SPL headroom, this model gives engineers full-range insight without the footprint of a full-size main monitor.

What Sets This Monitor Apart

The defining feature is the patented Image Control Waveguide. It shapes the acoustic output of the tweeter and woofer so they integrate without an audible gap, producing a broad, room-friendly sweet spot and precise stereo imaging even when the listener is off-axis. The patented Slip Stream low-frequency port then tunes the cabinet's air movement for tight, articulate bass. Onboard DSP room tuning with 81 combinations compensates for desk, shelf, or near-wall placement and adjusts the response to room acoustics or personal taste.

Driver Configuration and Acoustic Performance

Bi-amplified two-way architecture gives each driver its own dedicated amplifier, eliminating the compromises of passive crossovers.

• LF Driver: 6.5" (165 mm) long-throw woofer — reaches down to 43 Hz for accurate bass monitoring
• HF Driver: 1" (25 mm) soft-dome tweeter — smooth, detailed highs up to 38 kHz
• Maximum SPL: 112 dB peak — headroom for tracking loud sources and short-term peaks

Amplification and Signal Chain

Class D amplification keeps the cabinet cool and efficient while delivering the dynamic range modern productions demand.

• LF Driver Power Amp: 55 W Class D — tight control over woofer excursion for accurate bass transients
• HF Driver Power Amp: 55 W Class D — balanced dynamic range across the spectrum
• Crossover: 2040 Hz — phase-coherent transition between drivers

Connectivity, EQ and Room Adaptation

Professional connectivity and on-board room correction make this model easy to integrate into any studio signal chain.

• Inputs: Balanced XLR / 6.3 mm TRS combo jack — accepts +4 dBu and -10 dBV via sensitivity switch
• EQ: DSP room tuning, 81 preset combinations — adapts to placement and room acoustics
• Dimensions: 370 x 210 x 290 mm — compact footprint for desktop placement

Who Should Choose This Monitor

This monitor is the right choice for project-studio engineers, producers, podcasters and content creators who need trustworthy near-field monitoring with enough low-end reach to mix full-range material without a subwoofer. Its 6.5-inch woofer offers a meaningful step up in bass extension and headroom from smaller 5-inch monitors, while still fitting comfortably on a typical desk. Home recordists benefit from the 112 dB peak SPL headroom and wide sweet spot, which makes the monitors forgiving when multiple people listen at once. Post-production editors gain precise imaging that translates well to stereo and surround deliverables.
