Actual pictures to follow this evening.
Originally sold as a 3pc sub/sat set with the Monitor 6 series II shelf speakers. Small, passive subwoofer, bandpass configuration with two 6.5 inch woofs. No crossover needed, due to the tuned bandpass design. This sub sounds GREAT in a small room, and loads up down to the low 30's. I've used it in the home office rig for the past 5 years.
Good match for adding tuneful, low end punch to a pair of shelf speakers in the 89-92db 1w/1m efficiency range.
$85 shipped, lower 48.
Thanks for looking.
