QUARTZ-R
APPLICATIONS:
Concert PA systems
Auditorium Reinforcement
Discotheque Subwoofer
Cinema Subwoofer
QUARTZ-R The QUARTZ-R is a very high output concert INFRA
subwoofer system designed to minimize the space required to
obtain extremely high level and high fidelity low frequency output.
The QUARTZ-R provides perfectly flat response below 20 Hz
when used in conjunction
with the INFRA Integrator.
The
QUARTZ-R includes casters, handles, feet and pole mount
adapters for support of upper range speakers.
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-Aligned™
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 nocompromise, high fidelity reproduction systems. We believe they
are the finest subs available, regardless of price.

The Neutrik Speakon NL4MP connector is a keyed, high current, four conductor device which allows both the high and low frequency
signals for a bi-amped loudspeaker system to run through the same multi-conductor cable. Note that all four conductors on both
connectors are wired in parallel, but only two conductors are connected to the drivers in the enclosure. This permits an easy
parallel connection to other similar loudspeakers (if your amplifier can handle the low impedance load!) and allows the use of a
short “jumper” to connect to the mid/high speakers in a bi-amped system. Banana jacks are also provided on each circuit.
The Quartz has 2 input jackplates, each circuit with an impedance of 4 ohms, each powering 2 parallel 8 ohm drivers.
