Owner's Manual
W7AE Subwoofer Drivers: Tight.
The ultimate no-compromise subwoofer for those seeking extreme output and sublime sound quality.
1 - OverRoll™ Surround
By utilizing space wasted in conventional
speakers, this ground-breaking innovation controls
the W7AE’s massive excursion without sacrificing
precious cone area.
2 - W-Cone™
The W-Cone™ is a unit-body cone assembly that
delivers astonishing cone stiffness with minimal
mass. The shape also provides incredible torsional
rigidity, which is critical to maintaining voice coil
alignment at the suspension limits.
3 - Floating-Cone™ Attach Method
Ensures proper surround geometry in the
assembled speaker for better excursion control
and dynamic voice coil alignment. A small detail
that means a lot when you’re pumping the cone
to the excursion extremes the W7AE is capable of.
4 - Plateau-Reinforced Spider Attachment
A derivative of JLAudio’s famous VRC technology,
this bulletproof suspension attachment relieves
stress from the spider material at high-excursions
for enhanced reliability.
5 - Radially Cross-Drilled Pole Piece
This innovative venting system greatly enhances
thermal dissipation and power handling by
directing air flow onto the voice coil former,
working in conjunction with technology #6.
6 - Elevated Frame Cooling
The elevated frame design of the W7AE 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 improves
sound quality by minimizing dynamic parameter
shifts and power compression.
7 - Highly Linear, DMA-Optimized Motor System
DMA is JLAudio’s proprietary Dynamic Motor
Analysis system and is aimed at improving
dynamic motor behavior. As a result of DMA
optimization, W7AE motors remain linear
in motor force over an extreme range of
excursion and also maintain a highly stable
fixed magnetic field in the gap over a wide
power range. This leads to vastly reduced
distortion and faithfully reproduced transients...
or put simply: tight, clean, articulate bass.
8 - Huge Diameter, Progressive-Roll Spider
Arrived at after intense computer analysis and
optimization, the W7AE spiders provide precise
control and motor/voice coil alignment without
prematurely limiting excursion.
9 - Co-Extruded Double Lead-Wires
The extruded casing and carefully engineered
attachments ensure controlled lead-wire behavior
under the most extreme excursion demands. Two
conductors are used per connection for ample
current carrying capability.
10 - Ultra-long Voice Coil
To allow extreme linear excursion, phenomenal
power handling and control, control, control.
WARNING:
Prolonged exposure to high sound pressure levels can lead
to permanent hearing loss. W7AE subwoofers are capable of
reproducing sound at extremely high sound pressure levels.
Please exercise restraint in the operation of your system in order
to preserve your hearing and your long-term enjoyment of this
product’s sound quality capabilities.
