For consideration is a pair of ESS 6.5 midrange/woofer pair removed from Rock Monitor tower loudspeakers. These restored midwoofers are drop-in original OEM drivers from amt3. These drivers are to be wired out of phase as dictated by the original dividing networks - brown wire to the positive / yellow wire to the negative. I typically ship within 36~48 hrs of completed payment, Fedex, USPS or UPS. Thank you for looking.
