Description
Experience the quality of JL Audio 13TW5v2-2, a 13.5-inch Subwoofer Driver.
JL Audio has taken the ultimate thin woofer and made it even better.
The JL Audio 13TW5v2-2 exemplifies the brand's dedication to engineering innovation. Utilizing thin-line woofer technology, this unique driver features a "concentric tube" structure that supports the oversized voice coil and suspension attachments. This innovative design allows placing the large motor structure further forward in the speaker, resulting in exceptional linear excursion capability and mechanical stability.
This groundbreaking subwoofer driver boasts impressive performance despite its slim 67mm mounting depth.
Designed for tight spaces, the JL Audio 13TW5v2-2 optimizes enclosures much smaller than those typically required for 12-inch woofers. Yet it accommodates air space needs slightly larger than those of a standard 10-inch woofer. The design team also crafted the mounting system to fit within the same footprint as a standard 12-inch woofer, facilitating a seamless installation process.
With deep, powerful, and accurate bass, the JL Audio subwoofer delivers exceptional performance even in the most challenging installation applications.
Deep, powerful and accurate bass is now possible in the most challenging installation applications.
Their patented thin-line woofer technology compresses the JL Audio 13TW5v2's architecture using a “concentric tube” structure that supports the 7-inch diameter voice coil and the suspension attachments. This permits the large motor structure to be placed much further forward in the speaker than with conventional designs while allowing excellent linear excursion capability and mechanical stability.
The JL AUDIO 13TW5v2-2 is Engineered to perform
To unleash even more performance from this technology, the v2 improves upon the original JL Audio 13TW5 with 13% greater linear excursion capability. The engineers have modified the cast alloy chassis for greater strength and redesigned the motor to feature an annular vent. You can also choose the v2 in single 2-ohm and 4-ohm voice coil versions to fit various applications.
Staying true to its “tight-spaces” mission, the JL Audio 13TW5v2-2 optimizes enclosures that are much smaller than those required by most 12-inch woofers. It only needs a bit more air space than a typical small-box 10-inch woofer. The mounting system fits within about the same footprint as that of a standard 12-inch woofer.
The JL Audio 13TW5v2-2 delivers the best performance with amplifier power in the 250W—600W range, operating optimally in a 0.80 cu. ft. (22.7 l) sealed enclosure. Check the "Specifications" tab for detailed enclosure recommendations.
Now, you can achieve high-quality sub-bass even in the most challenging installation applications!
Dynamic Motor Analysis - DMA Optimized Motor
Summary:
JL Audio's Dynamic Motor Analysis system, developed in 1997, uses FEA-based modelling to address speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or, put simply, tight, clean, articulate bass.
Detailed Information:
Since 1997, JL Audio has led Finite Element Analysis for loudspeaker modelling. Their "Loudspeaker Genome" research studies loudspeaker performance using Dynamic Motor Analysis (DMA). Since the late 1990s, DMA has been vital in designing all JL Audio woofers, starting with the 15W3 and W7 subwoofers.
DMA is a Finite Element Analysis (FEA) --based system that analyzes complex problems by breaking them into smaller elements and assembling the data for an accurate overall solution. Its innovation is considering power effects through the coil and coil/cone position within a time-domain framework. This results in a precise model of a speaker's behaviour under real power. Unlike traditional Thiele-Small models, DMA accommodates shifts in circuit elements and requires hours of computation for a complete speaker analysis.
The payoff is reduced distortion, improved transient performance and stellar sound quality.
DMA can analyze the effects of fluctuating power and excursion upon the motor's magnetic circuit, specifically the dynamic variations of the "fixed" magnetic field. Compared to traditional modelling, this delivers intensely valuable information, which assumes that the "fixed" field produced in the air gap by the magnet and the motor plates is unchanging. DMA shows that this "fixed" field changes in reaction to the magnetic field created by the current flowing through the voice coil. It also helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behaviour is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behaviour:
- Linear motor force over the speaker's operational excursion range
- A consistent motor force with both positive and negative current through the coil
- Consistent motor force at varying applied power levels
JL Audio's analysis of motor behaviour helps their engineers adjust designs, resulting in stable and linear loudspeaker motor systems.
Floating Cone Attach Method - FCAM™
Summary:
This assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.
Detailed Information:
JL Audio's patented FCAM™ technology is an innovative method of bonding the surround/cone assembly to the voice coil former/spider assembly. This feature helps ensure concentricity of the surround, spider and voice coil without torquing the suspension to achieve it. This allows for the inevitable, slight variations in production part dimensions without having them negatively impact the integrity of the suspension and coil-centring at high excursions.
Tab-Ear Frame Design
Summary:
This frame design feature facilitates mounting the Subwoofer in tight spaces.
Detailed Information:
A tab-ear mounting system reduces the driver's size, enabling it to fit in areas similar to smaller round woofers. For example, the "Tab-Ear" design allows the 13TW5 13.5-inch driver to occupy only 0.44 inches more space than a standard 12-inch woofer.
Concentric Tube Suspension
Summary:
Their Concentric Tube Suspension™ technology delivers unprecedented excursion in a low-profile woofer.
Detailed Information:
The main challenge in designing low-profile woofers is ensuring sufficient mechanical clearance for effective excursion and low-frequency output. To meet ambitious performance goals, JL Audio developed a new suspension architecture. This design has a moulded structure that supports the spider outside the motor's boundaries, with a large voice coil allowing the magnet to sit inside it, unlike traditional woofers.
The concentric tube design and removal of the top plate allow JL Audio to position the motor system higher in the cone, enhancing depth and mechanical movement.
