Soundbar Accessories Guide: Mounts, Cables, and Placement

Quick answer

Buy accessories in this order: a mount or stable surface first, then the right cable for your TV's output, then small placement fixes like isolation pads or cable channels. If your TV sits on furniture, skip the wall mount and spend that budget on a better cable and a non-slip pad. If you wall mount the TV, mount the soundbar too so both sit at the same height.

Most soundbar disappointment comes from three things: it sits too low, it reflects off a shelf, or it is connected with the wrong cable. None of those are the soundbar's fault, and all three are fixable with accessories that cost far less than a new bar.

This guide covers what to buy, what to skip, and how to check fit before you order. It focuses on the accessories themselves, not on choosing a soundbar model, so you can improve the setup you already own.

Start with the mount decision, not the accessory list

Decide where the soundbar will live before you buy anything. If your TV stands on a media console, a mount is usually unnecessary; the bar can sit on the console in front of the TV. If your TV is wall mounted, a soundbar wall mount keeps the bar aligned with the screen and clears the console top for other gear.

The trade-off is flexibility. A mounted bar is harder to move when you rearrange furniture or add a projector, and mounting puts the bar's ports against the wall, which can make tight HDMI or optical connections awkward. Measure the gap between the bar's back panel and the wall before committing.

• Measure the TV's VESA pattern and the soundbar's mounting holes before ordering a bracket.
• Leave at least 2-3 cm behind the bar for cable bends if ports face the wall.
• If you rent, choose a mount that uses the TV's existing VESA points rather than new wall holes.

Cables: match the cable to your TV's output

The cable you need depends on what your TV and soundbar support, not on what sounds impressive. HDMI with eARC carries the most formats and lets the TV remote control volume, so it is the default choice when both devices have an HDMI ARC or eARC port. Optical is the reliable fallback for older TVs and works with almost everything, but it cannot carry lossless formats.

Buy the shortest cable that reaches comfortably. Extra length adds clutter and can strain a wall-mounted bar's port. If your TV only has optical out and your soundbar only has HDMI in, you need an HDMI-to-optical converter, not a different cable, so check both port panels before ordering.

• Label both ends of the cable before you push the TV back into place.
• Avoid right-angle adapters unless the bar's port is genuinely blocked; they can loosen over time.

Placement fixes that cost almost nothing

Height matters more than most people expect. A soundbar sitting on the floor or on a low shelf fires sound into furniture, which muddies dialogue. Aim for the bar's tweeters at roughly ear height when you are seated, or tilt it slightly upward if it must sit low.

If the bar sits on a hard console, it can rattle or slide. Rubber isolation pads or a non-slip mat solve both problems and cost very little. Keep the bar out of a closed cabinet; even a partly enclosed shelf traps sound and reduces the effect of any virtual surround processing.

• Keep at least 5 cm of clear space in front of the bar's drivers.
• Do not place the bar directly on top of a subwoofer or amplifier that vibrates.

When accessories are the wrong purchase

Accessories fix installation problems, not sound quality problems. If dialogue is still hard to follow after correct placement and a proper HDMI connection, a mount or cable will not change that; a different soundbar or a dedicated centre channel will. Similarly, a wall mount does not improve audio by itself, it only changes where the bar sits.

If your room has a large TV wall with in-wall or in-ceiling speakers already, a soundbar may be redundant. In that case, budget goes further toward an amplifier or architectural speaker accessories than toward soundbar brackets.

Decision rules for buying soundbar accessories

• TV on a console: Skip the wall mount. Put the bar on the console in front of the TV, add isolation pads, and spend the mount budget on a quality HDMI cable. No drilling, easier cable swaps.
• TV wall mounted: Mount the soundbar below the TV at the same width so dialogue stays anchored to the screen. Check VESA compatibility and port clearance before ordering. Measure the wall gap for cable bends first.
• Older TV with optical only: Buy an optical cable, not HDMI. Accept that some surround formats will not pass through, and set the soundbar to a stereo or movie mode that suits your room. Optical is reliable but format-limited.
• Dialogue still unclear after setup: Stop buying accessories. Re-check bar height and clearance, then consider a different soundbar or a centre-channel setup. Accessories fix installation, not tuning.

Relevant products from our catalog

• B2 Wall Bracket: Wall bracket for Q150 and Q350 bookshelf speakers, designed to mount Q Series speakers for better integration into the room. If you are considering wall-mounted speakers instead of a soundbar, this bracket is the mounting path for those specific bookshelf models, and it is not a soundbar mount.
• Ci160TS: Architectural speaker with KEF's Uni-Q driver array, a 4.5 in. mid/bass T Series driver, and a 1 in. tweeter, designed for slim installation spaces. Useful context if you are weighing a soundbar against in-ceiling speakers; its slim build suits tight ceiling voids, but it requires installation work a soundbar does not.
• KASA500 Amplifier: Amplifier listed in Architectural Speaker Accessories with a Color option. Shows the alternative path: if you move to architectural speakers, you will need amplification, which changes the accessory budget entirely.

Who this guide fits

Best for

• Owners of a soundbar who want better dialogue and cleaner cable routing
• Renters or apartment dwellers who need a reversible, low-damage setup
• Anyone deciding between a soundbar and wall-mounted bookshelf speakers

Not for

• Listeners who want a full surround system with dedicated rear and centre channels
• Rooms where in-wall or in-ceiling speakers are already installed and amplified
• Buyers shopping for a soundbar model rather than accessories

Buy the mount only if your TV is wall mounted, buy the cable your TV's output actually supports, and fix height and clearance before spending more. Those three steps solve most soundbar complaints, and they leave your budget free for upgrades that genuinely change the sound.
