Dual 18" subwoofer built tough and built to last. |
A good fit for PA Systems, clubs or auditorium reinforcement, the D18E-R is a very high output INFRA subwoofer system. It provides high-fidelity extended low-frequency audio reproduction unobtrusively, from a small enclosure. The D18E-R provides perfectly flat response down to 8 Hertz when used with the 8 Hertz Integrator. Designed for portable use, the D18E-R is ruggedly built and ncludes handles, protective corners, casters, a grille cover and a pole mount adapter. The enclosure on the D18E-R is carpeted to ensure ruggedness and remain unobtrusive.
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. |

| This is a GREAT sounding box! Very musical. The sealed design gives some very
nice low end. Do get the Integrator to go with it to get all the bass you can.
It's not the loudest sub out there, but it does well enough for most rooms and
what you get sounds sweet. That's why I chose the install version of this box
for my church where one box fills the 700 seat room. |
