| The
ONYX-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 ONYX-R provides perfectly flat response down below
20 Hz when used in conjunction with the INFRA Integrator. The ONYX-R includes
handles, a protective hard cover for the grille aperture, and also top and
bottom heavy duty dual L-track rigging attachment rails. It is designed
to integrate into existing touring sound systems, specifically those composed
of the EAW 850 and 853 series. ABOUT INFRA™ 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 subwoofers sound 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 subwoofer 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 low frequency systems available, regardless of price. |
