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