J-INFRA SUBWOOFER

THE J-INFRA IS THE INFRA SUBWOOFER FOR THE J-SERIES. IT IS AN
ACTIVELY DRIVEN 2-WAY BASS-REFLEX DESIGN AND EXTENDS THE FREQUENCY
RESPONSE OF A J-SERIES SYSTEM DOWN TO 27 HZ. IT HAS TWO BASS-
REFLEX CHAMBERS CONTAINING THREE 21" DRIVERS, TWO FACING FORWARD
AND ONE FACING BACKWARDS. THE CARDIOID DISPERSION PATTERN
RESULTING FROM THIS ARRANGEMENT AVOIDS UNWANTED ENERGY BEHIND
THE SYSTEM THAT GREATLY REDUCES THE EXCITATION OF THE REVERBERANT
FIELD AT LOW FREQUENCIES AND PROVIDES THE HIGHEST ACCURACY OF LOW
FREQUENCY REPRODUCTION.
THE J-INFRA CAN ONLY BE USED IN GROUND STACKED CONFIGURATIONS IN
CONVENTIONAL LEFT/RIGHT SETUPS AS WELL AS ARRANGED IN A SUBWOOFER
ARRAY.

THE J-INFRA CABINET IS CONSTRUCTED FROM MARINE PLYWOOD AND
HAS AN IMPACT AND WEATHER PROTECTED PCP (POLYUREA CABINET
PROTECTION) FINISH. THE FRONT AND REAR OF THE LOUDSPEAKER CABINET ARE
PROTECTED BY A RIGID METAL GRILL AND THE SIDE PANELS INCORPORATE
EIGHT HANDLES. FOUR 100 MM WHEELS ARE MOUNTED AT THE REAR.
