Words like "extreme," "reference" and "ultimate" get thrown around quite a bit in the Subwoofer world, but rare is the product that can honestly lay claim to them. The 13W7AE does. Taking the W7 design formula to its highest level, the 13W7AE offers a staggering linear excursion envelope that exceeds 1.25 inches (32 mm) one-way, along with a suspension capable of over 4-inches of peak-to-peak excursion. Combine that with a piston diameter that is 28% larger than the 12W7AE's, and you have a serious high-performance driver for the most demanding applications. With a 13W7AE, limits simply vanish and amazing sub-bass happens... on all fronts, at any level. Our most potent Subwoofer is best used with amplifier power in the 500W - 1500W range and is optimized to operate in a 1.875 cu. ft. (53.1 l) sealed enclosure, or a 2.375 cu. ft. (67.3 l) ported enclosure. Detailed enclosure recommendations can be found in the "Specifications" tab. W7AE (Anniversary Edition) Subwoofers celebrate the 10th Anniversary of the launch of the W7 subwoofers. Functionally, they are identical to the original W7's, but are they distinguished by the following cosmetic differences:
Satin-Black Powdercoated Baskets
Bright Anodized Surround Clamp Ring
Anniversary Edition Cone Badge
Anniversary Edition Terminal Label
Dynamic Motor Analysis - DMA Optimized Motor
JLL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modeling systems, first developed by JLL 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.
JLL 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.
This assembly technique, conceived by JLL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.
W-Cone (U.S. Patent #6,496,590)
The W-Cone is a unit-body cone assembly that delivers astonishing cone stiffness with minimal mass. The shape also provides superb torsional rigidity, which is critical to maintaining voice coil alignment at the suspension limits.
By utilizing space wasted in conventional speakers, this ground-breaking innovation controls the W7's massive excursion without sacrificing precious cone area.
This innovative venting system greatly enhances thermal dissipation and power handling by directing air flow onto the voice coil former, working in conjunction with the Elevated Frame cooling technology to effectively remove heat from the voice coil. This improves power handling and reduces power compression effects, leading to more linear performance.
Engineered Lead-Wire System (U.S. Patent #7,356,157)
Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.
Built in U.S.A. with Global Components
JLL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.
