3. Setup
3.1 Speaker Placement
Proper speaker placement is crucial for achieving optimal sound quality. Consider the following guidelines:
- Stereo Setup: For a traditional stereo setup, place the speakers equidistant from your primary listening position and spaced apart to form an equilateral triangle.
- Bookshelf/Shelf Mounting: When placing on a shelf or stand, ensure the speakers are at ear level when seated. Avoid placing them directly against a wall if possible. If wall-mounting, maintain at least a 1.5-inch air gap between the rear of the speaker and the wall to allow for proper bass port function.
- Room Acoustics: Experiment with toe-in (angling speakers towards the listening position) to fine-tune the soundstage and imaging.

3.2 Connecting Your Speakers
The R-50M speakers connect to your amplifier or receiver using standard speaker cables. Ensure your amplifier is turned off before making any connections.
- Identify the positive (+) and negative (-) terminals on both your amplifier and the R-50M speakers. The R-50M features red (+) and black (-) binding posts.
- Connect the positive (+) terminal of your amplifier to the red (+) terminal of the speaker.
- Connect the negative (-) terminal of your amplifier to the black (-) terminal of the speaker.
- Ensure all connections are secure to prevent signal loss or short circuits.

Once connected, your Klipsch R-50M speakers are ready for use. Turn on your amplifier or receiver and select the appropriate input source. Adjust the volume to your desired listening level. The R-50M speakers are designed for a wide range of audio content, from music to home theater applications.
