DESCRIPTION
The S12E-R is an Infra™ subwoofer system designed to provide high delity extended
low frequency audio reproduction from a relatively small enclosure. The S12E-R
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 the ampliers driving one or more S12E-R
systems. Designed for portable use, the S12E-R includes handles, durable grille and a
pole mount adapter on a black Ro Tex™ nished enclosure.

S12E-R 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 its superior time
domain performance, as well as its 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 both the upper frequency
roll off and the extended frequency response while
maintaining the hi sound quality often associated with a
sealed box design. 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 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
TM
to protect the system and unique to the Infra™
technology.
ABOUT OUR RO TEX™ FINISH
The durable Ro Tex™ nish is double layered on Bag
End™ “R” series or Road cabinets. And single layered on
installation or “I” cabinets. Ro Tex™ is a water born
environmentally safe nish. It’s uniquely strong and long
lasting. As it solidies it attaches and bonds to the
wooden cabinet to make a super hard and durable
permanent nish. Its light texture offers an attractive
and rugged nished look
ABOUT BAG END® LOUDSPEAKERS
Bag End loudspeakers began in 1976 in a small shop by
people dedicated to the pursuit of making high quality
loudspeaker systems. Over the decades Bag End® has
employed the very best construction techniques and
innovative acoustical designs into their products. The
ground breaking introductions of the Time-Align® and
ELF™ Technologies into sound reinforcement and studio
monitor loudspeakers in the 1980’s was followed by
Minima One™ self-powered systems and the highly
unique E-Trap™, electronic bass trap. Over the decades,
Bag End® has been a leader in providing uniquely good
sounding products and extraordinary service to our
customers world wide.
