JTR Speakers has added a new subwoofer to their lineup. The Orbit Shifter is an amazing product. This is a $3400 high efficiency horn subwoofer with a 4000 watt amplifier. The sound quality demonstrated in a system I recent worked on was incredible. This unit is 30″ tall, 22.5″ deep, 45″ wide and weighs 160 lbs. It would best be located behind an acoustically transparent screen due to its size and appearance.
