System Audio SA720AV Three-Way Floorstanding Speakers, Pair — Black Ash

A matched pair of System Audio SA720AV floorstanding speakers from the Danish manufacturer, finished in black ash veneer over MDF cabinets. Each speaker carries a three-driver array behind a removable silver-and-black grille — twin 5.5" bass/midrange cones flanking a central 4" dome midrange unit, with a rear-firing bass-reflex port. The cabinets wear the white front baffle with black trim that defines the AV series styling, and each is identified by the SA logo on the grille.

The rear panels carry gold-plated dual binding-post terminals with factory bridging straps for bi-wire or bi-amp configuration, mounted in recessed cups below the model and serial labels. Serial numbers 109896 and 114128 are present on the back panels. System Audio built the SA720AV as part of a home-theater-oriented lineup, positioning these as compact towers capable of full-range output — rated at 50–150W, 88 dB sensitivity, 8Ω nominal impedance, and a frequency response of 55–20,000 Hz.

CONDITION

Good. Cones are in good shape with no remarkable damage; the removable grilles show no visible damage. Cabinets show signs of previous mounting hardware along the top rear edges, light handling marks and scratching to the veneer surfaces, and minor veneer chipping at one top corner.
