Setting up a home theatre can improve your viewing experience, but simple setup errors often lead to poor sound, weak picture quality, and ongoing frustration. This guide covers common mistakes to avoid when setting up a home theatre, such as incorrect TV height, poor speaker placement, cable clutter, and unreliable internet connections. It explains how room layout, audio positioning, and equipment choices affect performance and comfort. Homeowners will find practical tips to improve sound clarity, viewing angles, and streaming reliability without unnecessary upgrades. These insights help create a balanced, functional home theatre that delivers consistent performance and long-term enjoyment.
Placing the TV at the Wrong Height or Distance
One of the most frequent home theatre setup mistakes is mounting the TV too high or too close. A screen placed above eye level forces viewers to tilt their neck, leading to discomfort during longer viewing sessions.
The ideal height places the centre of the screen at seated eye level. Distance also matters—sitting too close can cause eye strain, while sitting too far reduces image detail. Screen size, room dimensions, and seating layout should always work together.

Ignoring Room Acoustics
Many people invest in sound systems without considering how sound behaves in the room. Hard surfaces such as tiles, glass, and bare walls reflect audio, causing echo and unclear dialogue.
Simple improvements include:
- Using rugs or curtains to reduce reflections
- Avoiding speaker placement directly against walls
- Positioning centre speakers toward ear level
Balanced acoustics improve clarity without needing higher volume.
Poor Speaker Placement
Incorrect speaker placement is another common mistake to avoid when setting up a home theatre. Surround speakers placed too high or behind furniture fail to deliver directional sound.
Front speakers should face the seating area, while surround speakers work best slightly above ear level and angled inward. Subwoofers should not be placed in corners unless tested for sound balance.
Overlooking Cable Management
Loose or tangled cables not only look untidy but can also affect signal quality and safety. Poor cable routing leads to wear, interference, and accidental disconnections.
Wall channels, protective sleeves, and concealed conduit keep cables secure and improve the overall appearance of the setup.

Choosing the Wrong HDMI Cables
Using low-quality or outdated HDMI cables can limit resolution, refresh rates, and audio performance. Many issues blamed on TVs or receivers are actually cable related.
For modern systems, HDMI cables should support current video standards and be the correct length. Excessively long cables increase signal loss, especially in 4K setups.

Weak Internet Connection for Streaming
Streaming issues are often caused by poor Wi-Fi placement rather than the streaming service itself. Routers placed too far from the TV or blocked by walls reduce signal strength.
Improving router placement, using wired connections, or installing extenders can stabilise streaming quality.

Skipping System Calibration
Many home theatre systems include built-in calibration tools that adjust audio balance and speaker timing. Skipping this step leads to uneven sound and poor synchronisation.
Running calibration during setup helps the system match room size and layout, improving sound consistency across seating positions.
Forgetting Power and Ventilation Needs
Home theatre equipment generates heat, especially receivers and gaming consoles. Poor ventilation can shorten equipment lifespan and cause shutdowns.
Equipment racks should allow airflow, and power boards should include surge protection to guard against electrical damage.

Attempting Complex Installation Without Experience
DIY setups often work for simple systems, but larger home theatres involve structural mounting, cable routing, and configuration challenges. Incorrect installation increases the risk of damage or ongoing issues.
Professional assistance avoids repeated adjustments and ensures the system works as intended from day one.
