JBL D2 DUAL DIAPHRAGM DUAL VOICE COIL COMPRESSION DRIVER Best Quality Tweeter Harman 2025

Revolutionary D2 Dual Driver – Redefining High-Frequency Performance

JBL D2 DUAL DIAPHRAGM DUAL VOICE COIL COMPRESSION DRIVER Best Quality Tweeter Harman 2025 The groundbreaking D2 Dual Driver sets a new standard for high-frequency reproduction by delivering significantly greater output and clarity than conventional compression drivers. Featuring dual diaphragms and dual voice coils, the D2 design offers more than double the power handling, dramatically reduced distortion, and superior high-frequency response — all within the same compact footprint.

This advanced design translates to higher SPL, enhanced sonic detail, and a 30% reduction in weight, giving sound engineers a powerful advantage in both performance and efficiency.

Transducer Innovation at the Core of JBL Engineering

Transducer technology has always been the foundation of JBL’s engineering legacy. Building on the vision of founder James B. Lansing, JBL engineers continually push the boundaries of what’s possible—challenging convention and setting new industry standards in performance.

Rather than modifying existing designs, JBL develops transducer technologies from the ground up—often resulting in patented innovations. Breakthroughs like Differential Drive® woofers, CMCD™ cone midrange drivers, and the D2 Dual Voice Coil Compression Driver reflect a deep commitment to covering the full frequency range with maximum efficiency and fidelity.

By addressing critical challenges such as power compression, heat management, distortion, weight, and size, JBL has created a class-leading range of transducers designed to deliver exceptional performance across the most demanding professional audio applications.

Differential Drive® – High Performance with Reduced Weight

Powerful. Efficient. Patented.
JBL’s patented Differential Drive® technology redefines low-frequency transducer performance by delivering higher output, reduced distortion, and significantly lower weight compared to traditional single-coil designs.

Using dual voice coils and a dual magnetic gap configuration with a lightweight neodymium magnet structure, Differential Drive transducers offer superior heat dissipation, reduced power compression, and exceptional dynamic range. Integrated aluminum heat sinks and magnetically saturated pole pieces further enhance thermal management and minimize nonlinear distortion.

Engineering Innovation with Practical Benefits

JBL engineers approached a fundamental challenge in professional audio—how to increase performance while minimizing size and weight. The result was a radical rethinking of the traditional low-frequency driver architecture. By moving the neodymium magnets inside the dual voice coil assembly and eliminating the need for heavy external steel, JBL created a transducer that delivers:

Lighter weight – up to 50% less than conventional designs
Higher power handling – for greater headroom and reliability
Extended frequency response – with tighter low-end accuracy
Lower distortion – even at high SPLs
Smaller enclosures – reducing transport, setup time, and system footprint

This exclusive technology forms the backbone of JBL’s low-frequency driver lineup across touring, installed sound, studio monitoring, and cinema applications—empowering professionals with unmatched clarity, output, and efficiency.

CMCD® – Patented Cone Midrange Compression Driver

Precision Midrange Performance with Horn-Loading Advantages

JBL’s patented CMCD® (Cone Midrange Compression Driver) technology brings the benefits of horn-loading to midrange transducers, offering enhanced sensitivity, broader bandwidth, and consistent pattern control. Horn-loading also enables increased arrayability and reduces harmonic and intermodulation distortion—delivering higher maximum SPL and improved clarity in critical vocal and instrument frequency ranges.

High-Linearity, High-Efficiency Design

The CMCD family—CMCD-81J, CMCD-81H, and CMCD-61H—features a JBL-engineered cone driver coupled with a 3-slot annular-ring phasing plug and a thermally conductive rear chamber. Each model is designed with a 4-inch exit diameter and optimized exponential flare geometry, allowing for seamless integration with JBL’s Progressive Transition™ midrange waveguides. The result is a midrange transducer with outstanding accuracy, power handling, and system flexibility for high-performance sound reinforcement.

D2 – Dual Diaphragm, Dual Voice Coil Compression Driver

Redefining High-Frequency Performance

The D2 Compression Driver represents a breakthrough in high-frequency transducer design. Utilizing dual diaphragms and dual voice coils, the D2 offers more than twice the power handling and significantly reduced distortion compared to traditional single-diaphragm drivers. The result is a dramatic increase in high-frequency sound pressure levels—within the same compact footprint and at 30% less weight.

Compact Power, Superior Clarity

By merging two high-frequency elements into one transducer, the D2 delivers exceptional output, increased radiating surface area, and unmatched transparency—setting a new industry standard for line array systems and reference monitors. This patented design allows for higher array power, improved consistency, and greater dynamic impact, making the D2 an essential component in JBL’s most advanced systems.
