JLAudio E112 – 12 Inch powered subwoofer in gloss black finish. The subwoofer was a display unit and
demonstrated only when requested. The unit is a 9 out of 10 condition. The unit has
NO chips or scratches that are on the subwoofer.
The unit was on the floor for approximately 4 months. There is
NO cabinet marks, dents or chips of any type on the cabinet. There are only some of the light scratch/scuffs that one gets on black gloss finished speakers as several months of a unit is cleaned. Comparison of finish would be equal to if not
better than my listing of the Gotham g213 or REL G2. Unfortunately I have no pictures
to post but if you go to my positive feedback , my descriptions are accurate to
what I have said when buyers received their unit.
Shipping – Included
with purchase of the speaker within most contiguous US states(lower 48 states) only.
Shipping cost is added to buyers in Alaska, Puerto Rico, Hawaii, Guam and Virgin Islands.
Powered Subwoofer with
12-inch Subwoofer Driver, 1500 watts
Applying a series of
our key technologies, E-Sub powered subwoofers deliver exceptional sound
quality, power and value in a wide range of demanding applications
E-Sub drivers employ
our exclusive DMA technology to optimize the drivers' motor strength, ensuring
linear behavior over a very long excursion range. Unlike typical steady-state
modeling systems, DMA takes into account the dynamic shifts created by current
flow and back EMF under real power conditions, with real program material. The
payoff offered by DMA optimization is a driver that faithfully tracks its input
signal, at all listening levels, leading to superior bass definition and
The extreme mounting
depth of the E-Sub driver is very deliberate. It permits wide gaps to exist
between the three suspension elements (the rubber surround and the dual
spiders), imparting exceptional mechanical stability over the driver's full
excursion range. This further improves linearity, reduces distortion and
enhances long-term reliability. In a stroke of engineering elegance, the
E-Sub’s steel front mounting flange forms the entire front baffle of the
finished product, while the driver’s back-plate is threaded and bolted to the
rear wall of its enclosure for support.
To power these
innovative drivers, we engineered a completely new switching amplifier with a
regulated, switching power supply, making its chassis more compact, lightweight
and efficient, while still delivering ample, clean power to fully exercise the
E-Sub driver's performance envelope.
controlled from the E-Sub cabinet’s top panel, the amplifier incorporates
studio-grade signal processing to make adjustments a much more enjoyable
experience than rear–mounted controls found on most powered subwoofers. An
attractive cover hides and protects the controls during normal use.
The feature set has
been designed to allow the use of E-Subs in a wide range of applications, from
full home theater systems to dedicated two-channel music systems, to desktop
audio workstations. Analog inputs are provided for unbalanced line-level signals
or speaker level signals. Dedicated line outputs are included to make a
bi-amped system arrangement with no additional hardware required. Useful in
combating ground-related noise problems, a rear panel switch configures the
line level inputs as grounded or isolated.
The E-Sub’s active
crossover is a true two-way, 4th order Linkwitz-Riley design, with a low-pass
filter feeding the subwoofer's amplifier and a high-pass filtered signal
exiting its line outputs. When the on-board crossover is defeated, as is typical
in a home theater installation, the line outputs deliver a pass-through,
buffered signal identical to its line inputs, easily permitting multiple E-Subs
to be interconnected in a ‘daisy-chain' arrangement. Switchable polarity and a
fully variable phase control round out the signal processing section. All
signal processing is performed in the analog domain, ensuring very low latency
in critical applications.
