The Slant 8 was the effective replacement for the Centaur Major, but slightly shorter at 60" high 40" ribbon located vertically along the inner edge. (You can experiment by positioning the ribbons on the outer edges by switching L and R speakers.)

The woofer is a 8"  Vifa which is positioned 39" from the floor, hidden behind a grille cloth that covers most of the front face (and the grille cloth is not easily removed without a special service tool).

The woofer's front slot-loaded box tapers from top to bottom and is very rigidly constructed

Input is via two pairs of binding posts, so bi-wiring or bi-amping is possible.

A toggle switch on the rear adjusts the woofer output up or down by 2 dB.

The speaker comes with a set of four spikes and matching screw-in sockets in the base. Something to do when you have it properly positioned as they weight 120lbs each.
