3. Room positioning: Form equilateral triangle with listening position for optimal stereo imaging.
4. Toe-in adjustment: Angle speakers slightly inward toward listening position.

WARNING! Speakers are heavy; use proper lifting technique. Ensure stable placement to prevent tipping.

First-Time Setup

Connect speakers to amplifier/receiver following proper polarity.

1. Wire connection: Strip 10mm of insulation from speaker wire ends.
2. Polarity: Connect red terminal to amplifier's red (+) terminal, black to black (-).
3. Binding posts: Unscrew caps, insert bare wire or banana plugs, tighten securely.
4. Initial testing: Start with low volume, gradually increase to check performance.

CAUTION! Ensure amplifier is turned off during connection to prevent damage.
