Acoustic Monitor db IV High-End 3-Way Liquid Cooled Speaker EXCELLENT LOOK

Single Acoustic Monitor db IV high-end 3-way liquid cooled speaker in excellent condition. Cabinet has a few minor scratches, but speaker is in excellent condition overall. 10" woofer, and the cabinets measure 27x15x11. The 10" woofer cones are aluminum. Very fast attack. They are ported cabinets. 125 watts. Controls include a knob for the midrange and another for the treble frequencies. There is a reset button on the back panel, so I'm thinking there is a thermal protection circuit. I never ran them loud enough to trip the breakers. Included on the control panel is a graph showing how these speakers reproduce sound.
