For purchase is a pair of ESS amt3 dividing networks removed from rock monitor tower cabinets. Original Heil amt crossover pair, with new 250v capacitor upgrade.

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.
