Many speaker parts! From personal projects I tried out.
Altec 911b horns pair . They are cast steel or metal of some sort. The previous owner repainted them . Good condition except for a 1/4 x 1/2 inch spot where the paint or something bubbled up. I have not dug or picked on that spot. It seems quite solid in that spot. The horns themselves are 8 -1/2 high/18-1/4 wide--14 deep as best as i can measure. $100 for the pair plus shipping which i am willing to check out if you are interested.
