These Audio Point brass cones are 1.5" tall and have a 3/8" threaded stud so they can screw into speaker stands or equipment stands. I bought them to fit my Sound Anchor speaker stands for speakers which are now sold.
The cones are in fine condition. The threads are not stripped or damaged in any way. One of the cones has some scratches due to the previous owner using some pliers to unscrew it (see photo). The scratches are only cosmetic.
New cones are $38 each (see website at link) for a total of $304 for 8. My price for all 8 is $195 which includes shipping in the US and paypal fees.
