DESCRIPTION
The PS12E-I is a self-powered single 12” bass system designed for permanent
installation. The PS12E-I provides perfectly at response down to 8 hertz when used in
conjunction with the 8 hertz Integrator. Our external rack mount Infra-MXB Integrator is
recommended to drive a line level Infra™ processed signal to one or more PS12E-I
systems. The PS12E-I offers a black textured nish, a black coated steel grille and
optional y points.
The audio input incorporates an InGenius® balanced line receiver, providing very high
common mode rejection, to eliminate noise often present in systems with less
optimized grounding and wiring schemes. The internal Minima One™ amplier
incorporates a high efciency low power consumption green design with advanced
digital switching to automatically accept any line voltage from 88 to 270 volts. Low
voltage contacts are provided to remotely turn the amplier on and off.

PS12E-I INFRASUB
ABOUT INFRASUB™ TECHNOLOGY
Almost all designs and specications for subwoofer
systems are xated on the frequency response domain.
However, the impression of power and quality of a
loudspeaker is equally related to the time domain. The
long wavelengths associated with low frequencies make
this particularly true with subwoofers. Likewise, the
maximum SPL is not a very reliable way to judge the
impact of a subwoofer. A poor time domain performer
will not have the same impact or natural musically
connected sound as a Time-Aligned™ Infra™ system.
The reason that an Infra™ subwoofer sounds
dramatically better is because of their superior time
domain performance, as well as their extended low
frequency response. The Infra™ subwoofer maintains
the bass energy in a tight packet, aligned with the upper
range signal, providing a greater body impact and a
seamless musical connection with the main
loudspeakers. Conventional subwoofer designs perform
so poorly in the time domain because designers have
used methods that sacrice the phase response for more
control over the frequency response (e.g.: steep low pass
lter slopes, vented speaker enclosures, and narrow
bandwidth systems). With the Infra™ technique, we do
not degrade the phase response while extending the
frequency response.
While the Infra™ dual Integrator does function as the
system crossover, it does so without using a
conventional low pass lter. The Infra™ integrator
applies an inverse electrical response to the acoustical
response of the Infra™ loudspeaker in its sealed
enclosure. This provides the extended frequency
response while maintaining the hi sound quality often
associated with a sealed box design. This design
approach requires the most amplier power to be used
at the lowest frequency, thus we implement the
Dynamic Filter™ technology to protect the system from
the bottom up, affecting the lowest frequency rst and
leaving the middle and upper bass unaffected. The
Dynamic Filter™ is a complimentary technology to the
Infra™ system taking unique advantage of the Infra™
design approach, to implement a reliable protection
scheme that is transparent and inaudible to the listener.
When comparing a genuine Bag End® Infra™
loudspeaker system to any other, our technology and
design is easy to hear and appreciate. The dramatic
clarity, realism, and overall pleasant sound of an Infra™
system is well noted throughout the world.
ABOUT MINIMA ONE™
The Minima One™ is both a high delity and a high
efciency amplier. With efciency well over 80%, the
Minima One™ provides more power to the loudspeakers
and creates less heat in the amplier. In real world
applications there is practically no heat emitted from the
amplier and thus it requires no cooling fan.
Incorporating patented technology the comparison circuit
of the Minima One™ corrects every single cycle to drive
error to zero at the end of each cycle. On average, every
4 microseconds, the one cycle modulator transforms and
amplies the input signal into the ideal natural pulse
width modulation. Switching at 250 kHz with the single
TM
cycle error correction insures extremely low distortion
and high reliability. The power factor corrected AC
power input, automatically and continuously adapts to
any voltage between 88 and 270 volts. The Minima
One™ is convenient and stable to operate on any power
grid in the world.
ABOUT DYNAMIC FILTER™
The Dynamic Filter™ is a complimentary technology to
the Infra™ system taking unique advantage of the Infra™
design approach, to implement a reliable protection
scheme that is transparent and inaudible to the listener.
Systems using the external rack mount Infra-MXB
processor require an appropriate threshold adjustment
that sets the ampliers power and sensitivity to the
Infra™ loudspeakers in use. When a system is asked to
do more than it is capable of, or if an accidentally large
signal is presented the threshold of the Dynamic Filter™
is crossed and the system protects itself from the bottom
up by reducing the lowest frequencies rst. Since the
most power and excursion is always required at the
lowest frequency, reducing the level of the lowest
frequencies rst avoids an overload, while at the same
time the system is able to reproduce the middle and
upper bass and leave the upper crossover region
unaffected. This is a very natural and inaudible method
to protect the system and unique to the Infra™
technology.
