15-inch (380mm) 2219Nd Differential Drive Woofer
The 2219Nd is a 15-inch (380mm) woofer featuring JBL’s patented Differential Drive® technology with dual 3-inch (75mm) voice coils. Its pure pulp cone is paired with copper cap/Faraday rings to reduce AC inductance, lower distortion, and enhance midrange clarity and crossover performance. The motor is extensively FEA-optimized for up to 50% greater excursion, while dual opposing spiders (one inverted) help cancel non-linearities under high excursion. A newly designed cast-aluminum frame provides better venting and increased structural rigidity, ensuring superior performance and durability.
MultiCap ™ Crossover Network with Single-Wire and Bi-Wire/Bi-Amp Connectivity
By replacing traditional large capacitors with an increased number of smaller capacitors, this design results in lower ESR (Electro-Static Resistance) and less energy-loss in mechanical movement, culminating in greater signal throughput to the drivers, increased power handling, enhanced dynamics, ultra-low distortion, and exceptional clarity.
Dual Sets of Gold-Plated Binding Posts
Cast-aluminum terminal cup with dual sets of gold-plated binding posts for bi-wire/bi-amp usage with a shorting jumper for single-ended usage.
IsoAcoustics Feet
IsoAcoustics feet, crafted from precision-machined stainless steel, offer a sleek and durable solution for enhanced audio performance. They significantly reduce surface reflections from flooring, resulting in cleaner and more accurate sound. With a design that resists lateral movement and dampens oscillations, these feet provide exceptional isolation. Even during dynamic playback, they maintain perfect alignment with the listening position.
Bass Reflex with Dual Front-Firing Ports
The dual front-firing ports on the JBL 4369 enhance bass output and efficiency while allowing flexible placement, even near walls, without compromising sound quality. Compared to a single port, this design also smooths the frequency response at higher volumes, delivering more consistent and controlled low-end performance.
3-inch (75mm) D2830B Compression Driver Mated to Sonoglass HDI Waveguide
The 2830B compression driver is coupled to a patented Sonoglass High Definition Imaging (HDI™) horn/waveguide and features two ultra-light annular Teonex diaphragms, each with its own voice coil and neodymium motor structure. This approach matches the radiating area of a traditional 3-inch diaphragm while offering a significantly lower mass-to-motor force ratio. This dual-diaphragm design enhances high-frequency output, smooths and extends HF response, improves overall efficiency, and enables higher maximum output, reduced distortion, and double the power handling.
High Frequency and Ultra High Frequency Controls
System integration is optimized through high-frequency (HF) and ultra-high-frequency (UHF) controls, allowing precise adjustments from -1 dB to +1 dB in 0.5 dB increments. These fine-tuning options enable tailored sound performance for any environment, with HF adjustments covering the 1.5–6 kHz range and UHF adjustments targeting frequencies above 5 kHz.
Iconic Studio Monitor Design with Furniture Grade Cabinetry
The acoustic components of the JBL 4369 are housed in a classic Studio Monitor Series-style cabinet, featuring a clean and professional design. As the heaviest part of the system, the cabinet is built with 1-inch thick MDF walls plus an additional 5/8-inch added to the lower front baffle, creating a solid 1 5/8-inch thick support for the woofer. Structural rigidity is further reinforced by two strategically placed braces that connect all vertical panels, ensuring minimal resonance and maximum acoustic stability. The inert cabinet design eliminates coloration, preserving the purity of the sound.
Powerful Visual Aspect Ratio with HF at Optimum Height
The JBL 4369’s compression driver is precisely positioned to align with the listener’s ear level, ensuring high-frequency reproduction remains on-axis. This design refinement enhances clarity and imaging, delivering a more direct and immersive listening experience.
Available in Walnut and Black Walnut wood grain veneer finishes.
Attractive furniture grade wood veneer enclosure is internally braced at critical points and is tuned via dual front-firing ports.
