Steven Stone has posted a review of the Origin Acoustics Bassic SUB8 subwoofer ($) at HomeTheaterReview. His conclusions:
“The Origin SUB8 is a very attractive subwoofer with limited bass extension, power, and gain. It is best suited for music playback in a nearfield listening environment mated with medium-efficiency monitors. With high-efficiency monitors, the SUB8 lacks enough gain to produce adequate levels. Careful auditioning is recommended to make sure the SUB8 delivers adequate bass for your setup.”
