3-Way Component System: 6.5-inch (165 mm) Woofer, 4-inch (100 mm) mid-range, 0.75-inch (19 mm) Silk Dome Tweeter
The smoothness and transparency of a high-end silk dome tweeter combines with top-flight component mid-range driver and woofer performance to create a loudspeaker system with exceptional refinement and dynamic capability.
The C5-653 system features 6.5-inch (165 mm) component woofers with Kurt Müller cones and suspensions and die-cast alloy baskets. The woofer design benefits from JL Audio's vast woofer design experience and advanced modeling systems.
The 4-inch (100 mm) midrange drivers also benefit from Kurt Müller cones and suspensions and are built on a stamped steel chassis with removable mounting tabs. This allows them to be installed in a variety of mounting applications.
The C5 component tweeters are built with 0.75-inch silk dome diaphragms that deliver smooth, extended response, on and off axis. Flush-mounting and surface-mounting fixtures are included to fit a wide variety of installation needs. The flush-mount fixtures feature our RSR (Ratcheting Swivel Rotation) mechanism to allow precise tweeter aiming after installation.
C5 crossover networks are compact and built with premium component parts, including Mylar® capacitors and segmented air-core inductors. Four levels of tweeter attenuation are provided, as well as three levels of mid-range presence adjustment, for twelve possible voicing combinations!
Woofer and mid-range speaker grilles are included, each consisting of a black grille tray and a black steel mesh grille with an electroformed JL Audio logo.

Dynamic Motor Analysis - DMA Optimized Motor
JL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modeling systems, first developed by JL Audio in 1997 and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.
Since 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the "Loudspeaker Genome"... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.
DMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, "big-picture" solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.
DMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the "fixed" magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the "fixed" field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this "fixed" field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:
- Linear motor force over the speaker's operational excursion range
- Consistent motor force with both positive and negative current through the coil
- Consistent motor force at varying applied power levels
Our ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.
The payoff is reduced distortion, improved transient performance and stellar sound quality.
Elevated Frame Cooling
JL Audio's patented Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression.
Many speakers employ venting techniques to enhance voice coil cooling. This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.
Our patented design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.
Another important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame. The elevated frame technology greatly increases thermal power handling, reduces compression effects and does so without any additional parts.
Dr. Kurt Muller & Co.
The best sound requires cones and suspensions made to the highest standards in the world.
When the goal is superior component woofer performance, the things that truly matter are: consistency in cone mass, cone thickness and suspension compliance. This is why we turn to our partners at Germany's Dr. Kurt Müller & Co. for critical cone and suspension elements in our top-flight component woofers. Their track record of manufacturing precision and meticulous quality control is very well established in the loudspeaker industry; although most loudspeaker manufacturers prefer to avoid the premium that this quality commands.
While it has become fashionable to use stiff, exotic materials for component speaker cones, these tend to create upper mid-range colorations that require aggressive crossover designs and/or equalization to control. By contrast, Müller's low mass, mineral-filled polypropylene cones and butyl rubber surrounds are inherently well damped to deliver an uncolored, neutral midrange without any "artificial flavoring". This keeps crossover design simple and renders a smooth, clean mid-range presentation, on and off axis.
Dr. Kurt Muller & Co. also supplies the symmetrical-roll, hybrid-weave spiders used in the ZR woofers.
Silk Dome Tweeter
Light, fast moving silk dome material promotes high-frequency accuracy.
Silk is a natural material with inherently good characteristics as a tweeter diaphragm. In addition to being very light in weight, silk exhibits excellent damping properties, which reduces ringing and resonances in the tweeter’s passband, leading to a smooth, pleasing high-frequency character free from unnatural sibilance or exaggerated brightness. Compared to a harder material dome, a silk tweeter does not exhibit as much ultra-high frequency extension, but is preferred by many audiophiles for its overall balance.
