Quick answer

Thin sound from on-wall speakers usually comes from incorrect crossover settings, poor placement, or lack of boundary compensation. Adjusting these can restore fuller, richer audio.

Why on-wall speakers can sound thin

On-wall speakers are designed to be close to the wall, but that proximity can cause bass cancellation or reflection issues if not set up correctly. Many receivers assume speakers are placed on stands, so default crossover settings may let the speaker try to reproduce low frequencies it can't handle well in that position.

Another common cause is aiming: on-wall speakers often fire straight ahead, but if your listening position is off-axis, you lose high-frequency detail and perceived fullness.

Diagnosis steps

  • Symptom: Sound lacks bass, sounds hollow or distant, especially at low volumes.
  • Likely cause: Crossover set too low (e.g., 40 Hz) for the speaker's size and placement, or receiver is set to 'Large' speaker mode. Also: speaker too close to a corner or too far from the listening position.
  • Corrective action: Set crossover to 80 Hz or higher in your receiver's speaker setup menu. Change speaker size to 'Small' if available. Move the speaker at least 6 inches from side walls and avoid corners. Angle the speaker slightly toward the listening position if possible. After these changes, listen to a familiar track. If sound is still thin, proceed to the next step.
  • Stop or choose another option: If adjusting crossover and placement doesn't help, consider adding a subwoofer. On-wall speakers like the Novus N6SC are not designed to produce deep bass alone; a subwoofer will fill in low frequencies and make the system sound full. If you're still dissatisfied, the speaker may not match your room size or listening preferences. At that point, consider a larger on-wall model or a different speaker type.
