Bag End ISUB2-10

The ISUB2-10 is a self powered professional subwoofer system. It employs stereo summing management combining two inputs for a mono summed bass system.

The signal is processed by the INFRA dual integrator driving a 700 watt power amplifier into a front firing 10" cone loudspeaker in a sealed box. This provides a flat acoustical response down as low as 8 Hertz. Two iso- lated inputs allow the combining of a stereo signal for mono summed bass. Two units can be used separately for stereo bass systems.

DYNAMIC FILTER: The internally set Dynamic Filter protection maintains undistorted audio reproduction under accidental overload conditions. An optional remote indicator module (REMCON- 2) may be placed in a convenient, visible location to indicate the dynamic filter protec- tion threshold has been reached.

The INFRA driver is operated below resonance and flattened with an electrical boosting circuit, the INFRA dual integrator. Operating below resonance the INFRA sys- tem exhibits predictable, uniform response and reproduces each note with the same emphasis, reducing the influence of the res- onances found in conventional above reso- nance bass systems. In addition, the use of a low pass filter is eliminated (and with it the associated long variable delay) and replaced with the INFRA dual integrator with its short uniform delay.

Upon close listening, it is clear that the impression of power and impact is greater with an INFRA system when compared to conventional bass systems. This is true even when the two systems will measure the exact same Sound Pressure Level on a calibrated SPL meter. This is because the INFRA sub- woofer maintains the bass energy in a tight packet, aligned with the upper range signal, providing a greater body impact and a seam- less musical connection with the main loud- speakers.

Objectively, the INFRA system exhibits supe- rior frequency and phase response.
