All in excellent condition. I'm looking for an amp stand... maybe you are looking for a speaker stand? The 2 pairs with the U-Shaped bases are all the same and stand 24 inches high with the speaker "table" 7 1/2 inches square. The base is 11 inches wide X 12 inches deep. The 2 with the T-Shaped bases stand 27 1/2 inches high with the speaker "table" 6 1/4 inches square. The base is 14 inches wide X 12 inches deep. THX.
