MINIMA ONE SELF-POWERED The P-D18E-I is a very high output
self-powered subwoofer system designed to provide high fidelity
extended low frequency audio reproduction from a relatively small
enclosure. The P-D18E-I provides perfectly flat response down to 8
Hertz when used in conjunction with the 8 Hertz Integrator.
Designed for permanent installation, the P-D18E-I offers a flat black
textured finish and a black coated steel grille.

OPTIONAL CUSTOM FINISHES

Available in white and ready-to­stain natural birch. Also available in custom outdoor weather resis­tant finish for greater versatility in location and aesthetics.

ABOUT INFRASUB TECHNOLOGY

Almost all specifications for sub­woofer systems are fixated on the frequency response domain.
However, the impression of power and quality is equally related to the
time domain performance of a system. Because of the long wave­lengths of low frequencies, this is 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 sound as a time correct INFRA system.

The reason that INFRA technology sounds dramatically better than
the others is because of their superior time domain performance. 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 subwoofers designs perform so poorly in the time
domain because designers have used methods that sacrifice the
phase response for more control over the frequency response (e.g.,
steep low pass filter 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 low pass filter. Adding a low
pass filter, analog or digital, will have a degrading effect on the
time domain performance of the INFRA subwoofer. A low pass filter
adds signal delay to the sound which varies with frequency. Also,
narrowing the pass band increases the influence of the rolloff on
both ends of the subwoofer spectrum. The result is the smearing of
the arrival times of the low frequency sound components, changing
the timbre and downgrading the impact of transient sounds.

The Bag End INFRA subwoofers are designed as no-compromise,
high fidelity reproduction systems. We believe they are the finest
subs available, regardless of price.

ABOUT

MINIMA ONE AMPLIFIER

T

ECHNOLOGY

The Minima One amplifier is
both a hi fidelity and a high efficiency amplifier.
More than 80% efficient the Minima One
provides more power to the loudspeakers and
creates less heat in the amplifier. In real world
applications there is practically no heat emitted
from the amplifier and thus 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 ampli­fies the input signal into the ideal natural pulse
width modulation. Switching at 250KHz with
the single 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 to power and stable to use
on any power grid in the world.
