The Hartsfield is the one speaker that always appears much larger than they are in photos.
You imagine them to almost be as tall as you and the top almost meeting your neck, but they are quite a bit smaller.
I am pretty sure the Hartsfield are also known as the JBL D30085, and according to specifications measure 1162mm x 1194mm x 662mm.
Making them around average waist height.
Also there are 3 versions of the speaker, one which is only 2-way with a small 8" woofer, and two other versions using a bigger 15" woofer I am not sure about details on.
