To adjust the tweeters on the PROFICIENT AUDIO SYSTEMS C641 2-Way Graphite Ceiling Speakers, follow these steps:

1. Start by removing the grille from the speaker baffle.
2. The speakers come from the factory with the tweeter facing straight out from the baffle, which provides the overall smoothest response.
3. Depending on your particular primary listening area, room acoustics, ceiling height, or personal preference, you may find the sound more pleasing by pointing the tweeters in a particular direction.
4. If additional treble is desired in the primary listening area, gently push the edge of the tweeter to point it towards that area. If less treble is required, point the tweeter away.
5. Avoid touching the metal dome tweeters, as damage may occur.
6. The tweeters on the C641 model are not pivotable, so the adjustment is limited to pointing them in the desired direction.

Please refer to Diagram 3 in the user manual for a visual representation of the tweeter adjustment process.

Note: The C641 speakers also have a switch labeled TREBLE that allows for 3dB of treble adjustment. By default, the switch is in the "-" position, providing the most linear frequency response. If you desire more treble, move the switch to the "+" position, and the tweeter will play 3dB higher. To return to the neutral setting, push the switch back to the "-" position. This adjustment is separate from the physical pointing of the tweeters.
