A soundbar for TV can noticeably elevate your audio experience when it includes the right technology. Here are the key features to look for:
Immersive 3D Sound: Models featuring Dolby Atmos technology and DTS:X use upward-firing drivers. These drivers create a three-dimensional soundstage where audio moves around and above you. Standard 2.4-metre rooms provide ideal conditions for this technology.
Clear Dialogue: Dedicated centre channels ensure you never miss a word during complex action scenes. Premium soundbars also support high-resolution formats such as FLAC and WAV.
Deep, Clutter-Free Bass: Pair your soundbar with a powerful wireless subwoofer for low-frequency impact without cable clutter. Frequency response below 40Hz delivers rumbling bass for action content.
Smart Connectivity: Built-in HDMI eARC allows for uncompressed transmission and easy setup. This gives you seamless volume control with your TV remote.
Higher ceilings may need more powerful upward-firing units to achieve the same effect as standard rooms. Wireless subwoofers with drivers measuring 6-8 inches provide balanced performance across films, music, and gaming hardware applications.
Essential connectivity features include:
Smart soundbar technology enables whole-home audio networks that synchronise playback across multiple rooms. Channel configurations range from 2.1 systems with basic stereo output to 7.1.2 setups featuring seven forward-firing speakers, dedicated bass, and overhead effects.
Soundbar Sizes: Matching Audio Power to Room Size
Match soundbar length to two-thirds or three-quarters of your TV width for visual balance. A 55-inch television measuring 122cm wide pairs naturally with 80-100cm soundbars. Room size determines power requirements. 10-15m² spaces need 200-400 watts. 15-25m² rooms require 400-600 watts. Spaces over 25m² benefit from 600+ watts total output.
TV stand depth (typically 40-50cm) must accommodate soundbar depth (10-15cm) without blocking screens or IR sensors. Soundbars above 8cm height may obstruct smaller displays when placed directly in front. Cabinet installations need 5-10cm clearance on all sides for proper ventilation. Samsung soundbars and Bose models offer compact designs suited to various entertainment unit dimensions. Beamforming technology in premium models bounces sounds around rooms to create surround effects without additional speakers.
Soundbar Compatibility with Smart TVs & Streaming Devices
HDMI ARC and eARC make setup simple by sending audio through a single cable. This still lets you adjust volume with your TV remote. HDMI 2.1 ports offer 48Gbps bandwidth. This enables 4K at 120Hz and spatial audio for PlayStation 5 and Xbox Series X gaming. Earlier HDMI 2.0 ports support 4K at 60Hz and work with compressed audio formats.
Optimising Audio Quality with the Right Soundbar Connections
Connect 4K media players and streaming devices directly to soundbar HDMI inputs for optimal audio processing. This maintains Dolby Atmos compatibility on Netflix premium tiers, Disney+, and Amazon Prime Video 4K titles. TV cables including optical connections provide alternatives for older televisions. They carry compressed Dolby Digital at 36Mbps bandwidth.

Wall Mounting vs TV Stand Soundbars
Wall mounting saves furniture space and positions sound at ear level. It requires anchors rated for 3-8 kilograms. Wall proximity boosts bass response through boundary reinforcement in smaller rooms.
Stand placement offers easier repositioning and direct projection without wall interference. Side-firing drivers in models from JBL create wider soundstages when unobstructed by walls. Premium soundbar options include mounting brackets for both installation types. Some systems pair with wireless speakers positioned at room rear for authentic surround sound.
