ESS amt1a, 1b, 1c, 1d, type grill covers. Fitment of these tops are for the truncated ESS floorstanding loudspeakers. These are both in uncommonly great condition. The frames are strong and intact. The grill material is undamaged and clean throughout. You will be pleased with this set, should you decide to update your existing old grill tops. Ive marked the shipping cost at 118.00 and will refund the buyer any overages, should that come into play. They will be carefully packed in 1 extra large sturdy carton. I usually ship within 36-48 hrs of a completed purchase, but may need extra time to pack them well. Thank you for looking.
