Advent Legacy III are two way floor speakers have 100 watt power handling capacity and can be switched from I ohms to 6 ohm...
Overall the cabinets are good shape... But one of the speakers needs its tweeter replaced. The 10" cones work well and have nice bass.
The are project, but should work quite well when rehabilitated.
From Hi-Fi Review:
The Advent Legacy III is a two-way floor-standing speaker system using a 10-inch woofer and a 1-inch soft-dome tweeter with magnetic-fluid damping. The woofer is unusual in having a dual voice coil that enables the system impedance to be set at either 6 or 8 ohms by means of a toggle switch on the back of the cabinet near the input terminals.
The manufacturer recommends using the 6-ohm setting when the amplifier is driving a single pair of speakers, since that will deliver the system's maximum sensitivity (efficiency). If two or more pairs of speakers are driven in parallel, as they might be in a multiroom installation, for example, the 8-ohm setting lightens the load on the amplifier.
The Legacy III's cabinet is made of 3/4-inch particle board covered with black textured vinyl, with a solid pecan top plate and base trim. The front is covered by a removable black cloth grille. The woofer, operating in a sealed enclosure, is at the midpoint of the front grille, with the tweeter above it, near the top of the front panel. The input connectors, spring clips designed to accept only wire ends, are recessed into the rear panel, together with the impedance switch.
