Soundbar Accessories FAQ: Mounts, Cables, and Remote Tips

Quick answer

Most soundbar accessory problems come down to three things: matching the mount to your wall and bar weight, choosing the right cable for the audio format you actually use, and pairing the remote correctly. Buy the mount first if you are wall-mounting, then the cable, then any remote or control accessory. If your bar already sits on furniture and uses the TV remote over HDMI, you may need no accessories at all.

Soundbar accessories are a small category with a lot of confusing overlap. A mount, a cable, and a remote can all be sold as "soundbar accessories," but they solve completely different problems, and buying the wrong one is the most common reason people end up returning something.

This FAQ answers the questions that come up most often before and after a soundbar purchase. Each answer stands on its own, so you can jump to the one that matches your situation rather than reading a general setup guide.

Do I need a soundbar mount, or can I just place it on furniture?

A mount is only necessary when you want the bar off the furniture, usually to keep the TV top clear or to raise the bar closer to ear level. If your TV stand has a clear shelf in front of the screen and the bar does not block the bottom of the picture, placing it there is simpler, cheaper, and easier to adjust later.

Wall mounts and under-TV mounts solve different problems. A wall mount fixes the bar to drywall or studs and gives you the most placement freedom. An under-TV mount attaches to the TV's VESA pattern and moves with the screen, which helps in rental spaces where you do not want new holes in the wall. Check the mount's weight rating against your bar before buying.

• Measure the distance from the TV's bottom edge to the furniture surface before choosing an under-TV mount.
• For drywall, plan to hit at least one stud or use heavy-duty toggle anchors rated for the bar's weight.

Which cable should I use to connect my soundbar?

Start with the connection your TV and bar both support best. HDMI with eARC carries the highest-quality audio and lets the TV remote control the bar's volume, so it is the first choice when both devices have the port. Optical is the reliable fallback and works on almost every TV, but it cannot carry the same bandwidth as HDMI eARC.

If you are connecting a subwoofer or surround speakers to the bar, use the cable or wireless pairing method the bar was designed for rather than a generic substitute. Cable length matters more than most people expect: a short cable that forces the bar to sit at an odd angle is worse than a slightly longer one routed neatly behind the furniture.

• Label both ends of the cable before you route it behind a wall or cabinet.
• Avoid running audio cables parallel to power cables for long distances to reduce hum.

Why is my soundbar remote not working?

Check the battery and the line of sight first. Many soundbar remotes are infrared and need a clear path to the bar's sensor, which is often on the front or top edge and easy to cover with a decorative object. If the remote uses Bluetooth, it may need to be re-paired after a firmware update or a power outage.

If your goal is to stop using the soundbar remote altogether, enable HDMI-CEC on both the TV and the bar. That lets the TV remote handle power and volume for the bar, which is usually enough for everyday viewing. Keep the original remote nearby for input switching and sound mode changes that the TV remote cannot reach.

• Point the remote directly at the bar's sensor from within a few feet when testing.
• Re-pair Bluetooth remotes after any firmware update before assuming the remote is faulty.

Are soundbar accessories worth buying at all?

Buy accessories to solve a specific problem you can name, not to complete a set. A mount is worth it if the bar is in the way or too low. A cable is worth it if the supplied one is too short or cannot carry the format you use. A remote or control accessory is worth it if the current remote is genuinely inconvenient.

The one accessory category that is easy to overspend on is decorative trim and cable covers. They improve how the setup looks, which is a real benefit, but they do not change sound quality. Decide how much appearance matters to you before adding them to the cart.

• Write down the problem the accessory solves before buying it.
• Skip accessories that only duplicate a function the TV remote already handles.

Can I use accessories from a different brand?

Universal mounts and standard cables usually work across brands because they follow common standards like VESA and HDMI. Brand-specific stands, plinths, and mounting systems are a different story: they are shaped for particular speaker or bar dimensions, and a generic substitute may not fit or may not hold the weight safely.

When you are matching a stand or mounting system to a specific speaker, use the manufacturer's own accessory if one exists. The KEF S2 Floor Stand and S3 Floor Stand are examples of stands designed to partner specific speaker models, with integrated cable management and, on the S3, the option to add inert filler for stability. A generic stand will not offer that fit or those features.

• Confirm VESA pattern and weight rating before buying any universal mount.
• For brand-specific stands, check the manufacturer's compatibility list rather than guessing from photos.

Soundbar accessory quick checks

Mount fit

Confirm the mount's weight rating and VESA pattern match your bar and TV before drilling or ordering. If you cannot find the weight rating, do not buy the mount.

Cable format

Use HDMI eARC when both devices support it; fall back to optical only when they do not. Match the cable to the format you actually use, not the most expensive option.

Remote control

Enable HDMI-CEC to let the TV remote handle power and volume, and keep the soundbar remote for input and sound mode changes. Re-pair Bluetooth remotes after firmware updates before replacing them.

Accessory facts worth knowing

• S2 Floor Stand: Designed to partner LS50 Meta, LS50 Wireless II, and other KEF standmount speakers, with a mounting system that includes integrated cable management and spike discs to protect wooden floors. If you own one of those speakers, this stand hides the cable run and protects hard floors without extra parts.
• S3 Floor Stand: Designed to partner the R3 Meta bookshelf speakers, with integrated speaker cable management and the ability to be loaded with inert filler to improve stability. The filler option lets you add mass for a more stable platform, which matters in rooms with foot traffic or uneven floors.

Soundbar accessories are simple once you separate the three jobs they do: hold the bar, carry the signal, and control the volume. Solve the problem you actually have, confirm compatibility before buying, and skip anything that only duplicates what your TV remote already does.
