JL Audio C5-400cm-RP 4″ Component Midrange Driver – 49022
JL Audio C5-400cm-RP superbly-balanced 4-inch (100 mm) mid-range component speaker benefits from Kurt Müller cones and suspensions. The speaker is built on a stamped steel chassis with removable mounting tabs, which allows it to be installed in a variety of mounting applications.
A grille is included, consisting of a black grille tray and a black steel mesh grille. The grille tray also serves as a narrow-diameter mounting flange when the metal ears are removed from the speaker’s frame.
The C5-400cm is designed to operate within a bandwidth of 300 Hz – 5 kHz. No crossover filter is provided with this speaker.
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.
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.
Elevated Frame Cooling (U.S. Patent #6,219,431 & #6,229,902)
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.
