Place the speakers 6‑8 ft (1.8‑2.4 m) apart, angle them 40‑60° toward the listening position, keep at least 20 in (50 cm) from side walls, and avoid heat sources or direct sunlight.
The speaker accepts gold‑plated jumpers, bare wire, pin connectors, flat splice plates, and banana plugs; always observe polarity (+ red, – black) and secure the jumpers to prevent short circuits.
Use the front‑panel controls to adjust HF and UHF levels; set both controls to 0 dB to restore factory defaults.
