Carefully remove the speaker from its packaging. Retain all packaging materials for future transport or storage. Inspect the speaker for any visible damage.

3.2 Speaker Orientation and Pairing

The D15 speaker features offset tweeters designed for optimum stereo imaging. It is essential to purchase both a dedicated left-channel and a dedicated right-channel speaker to form a true stereo pair. Ensure the speakers are positioned correctly according to their left/right designation for accurate soundstage reproduction.

3.3 Room Placement

• ໄລຍະຫ່າງຈາກຝາ: For optimal sound, especially for bass response, position the speakers approximately 2 to 3 feet away from the rear wall. This allows the sound from the rear-firing passive radiators to reflect and enhance the soundstage without causing excessive bass buildup.
• ການແຍກສະເຕຣິໂອ: Place the left and right speakers equidistant from your primary listening position, forming an equilateral triangle. Adjust the toe-in (angle towards the listener) slightly to fine-tune the stereo image.
• ຄວາມໝັ້ນຄົງ: The speaker includes a cast aluminum base with spikes and floor glides. Use the spikes for carpeted surfaces to couple the speaker firmly to the floor, reducing unwanted vibrations. Use the floor glides for solid surfaces like hardwood or tile to protect the floor and maintain stability.
