A Guide to Bluetooth Ceiling Speakers

Understanding Bluetooth Ceiling Speakers

All Bluetooth speakers or amplifiers rely on wireless audio transmission to play music from a paired device, usually a smartphone or tablet, that provides playback from websites such as YouTube, or music apps such as Apple Music or Spotify.

Modern systems typically use Bluetooth 5.0 or later, offering:

• Improved range (up to 40 metres in ideal conditions).
• Lower latency for better synchronisation with the audio from video.
• Higher data transfer rates for improved sound quality.
• Some advanced models support aptX codecs, which further enhance audio quality by reducing compression loss.

The thing to understand about Bluetooth is it uses UHF radio waves in the 2.4 GHz range for transmission and reception. The range is dictated by the size of its transmitter, and the power it’s allowed to consume. With mobile devices such as phones, it's a small bit of circuitry and is limited to milliwatts of power, both to limit battery usage and to stop unwanted heat production. These factors give you an average of 10 metres of usable range, or up to a possible 40 metres with the low-energy Bluetooth version 4.0 and above, though this is reduced significantly by the environment (walls, doors etc).

This is why Bluetooth is not used for longer-range communication and data transmission, with WiFi usually stepping in to take its place once distance becomes involved.

For most home users though, 10m (32ft) is more than enough, as the average living room or kitchen is simply not that large, and with Bluetooth’s ease of use and availability in most modern devices, it offers the simplest method of listening to music wirelessly without requiring any sort of network connection.

Additional Features of Bluetooth Speakers to Consider

Speaker Size & Features

You will find that most ceiling speakers start at a 5.25-inch diameter (133mm), with the next size up being 6.5-inch (165mm), going up to 8-inch (203mm) as the largest. You can also go smaller, with 3-inch (76mm), and even 2.5-inch (63mm) units designed to fit the space left by a standard downlight.

• 2.5-inch to 3-inch - The smallest size of ceiling speakers available. These are primarily designed for low-volume background sound. Their physical size limits their capability to produce bass frequencies.
• 5.25-inch - Ideal for most users. This is the industry standard size for ceiling speakers, giving a great mix of clear sound and plenty of volume capability.
• 6.5-inch - For the more discerning music listener, the larger 6.5” driver size is commonly found on HiFi bookshelf speakers. It provides a better bass response and an increase in performance while remaining unobtrusive.
• 8-inch - The largest size available for most ceiling speakers. An 8” woofer provides a fairly significant increase in bass response that can be ideal for larger rooms and higher ceilings that may sound a bit lacking with smaller speakers.

As always, it's a personal choice. Most portable Bluetooth speakers use a 2.5-inch or 3-inch driver so there is nothing wrong with using that size, but it’s important to understand that a ceiling speaker creates its low-end frequencies by using the ceiling cavity as an enclosure, so the bass and midrange it produces is directly linked to its drivers surface area.

For most users, the difference in sound quality and performance makes it a no-brainer to fit either a 5.25” or 6.5” speaker set, as they offer a far superior frequency range and higher volume capability. You can go further by fitting 8” drivers, though you may find that the relatively low power output of most compact Bluetooth amplifiers will struggle to provide the extra push they require to sound much different to a good 6.5” unit.

Coaxial Tweeters

Standard ceiling speakers use full-range drivers, meaning that their woofer is producing all the frequencies, from bass to treble. While this is perfectly fine, and the sound produced is good enough for most tastes, they can sound lacking in the finer detail, and will struggle to produce a wide soundstage.

A ‘coaxial speaker’ remedies this with the addition of a smaller tweeter driver, usually mounted on a central post or frame above the woofer. Running via a built-in crossover, this 2-way design separates the high frequencies away from the mids and bass, producing a much more detailed sound.

Coaxial designs provide far superior frequency separation, which makes your music really come alive, and you will find that the majority of good quality ceiling speakers aimed at home installation will use this format.

Multi-Room Audio Compatibility

Some Bluetooth ceiling speaker systems support multi-room audio, allowing you to sync music across different areas of your home. This requires them to support a WiFi connection.

Bluetooth is basically a line-of-sight transmission between transmitter and receiver and is not capable of multiple, simultaneous connections. This is where WiFi comes into play, along with specialist audio system apps such as 4stream or Legacy.

These apps allow you to find any WiFi-enabled amplifier or active speaker on the network and group them together in any manner you choose, allowing you to play the same audio throughout the home, or just to specific rooms.

WiFi grouping apps also allow you to play audio from a network-connected device, which could be a home PC, an audio storage drive (NAS or similar), an internet radio etc.

If you are looking at Bluetooth ceiling speaker systems for the home and you are thinking of multi-room playback, the inclusion of WiFi or a wired ethernet connection will be essential for that type of functionality, so keep that in mind.

Additional Connectivity Options

While the main event is their Bluetooth connection, most active ceiling speakers or wall-mount amplifiers will also include at least one other audio playback option to allow their use when no streaming device is available.

AUX Input - The term AUX is generally reserved for a 3.5mm mini jack plug input, though it can also refer to RCA sockets or even bare-wire terminals. Whichever it has, the AUX connection is designed for a standard line-level audio signal, usually stereo.

This can come from all sorts of devices, from a CD player, Laptop or PC, to the audio output of a games console, Blu-Ray player, or TV. Obviously, this requires a physical cable to connect between the device and the amplifier, so that means up a wall and into the ceiling for most cases. This doesn't have to be direct though, and the sensible thing to do is run the cable from the amplifier or active speaker to a 3.5mm socket somewhere, either on a loose cable that can be tucked out of sight, or to a fixed wall plate, which you can connect to when needed.

Digital/Toslink - This can be a traditional Toslink optical connection or the newer 3.5mm optical jack. These are handy, as most modern TVs only have a digital audio output. If your TV is digital out only, and your Bluetooth amplifier is AUX or line-input only (which are both analog), you will need a converter box to be able to hook them up.

USB/SD - Wall-mount amplifiers tend to include a built-in MP3 player, allowing you to playback MP3 audio files stored on either a USB thumbstick or SD card. This can be convenient for background music that will play on a loop.

Radio - FM or even DAB radio reception may be included, especially on higher-end wall-mount systems. This is a big selling point for many still, and it adds great usability to a home audio system, with the latest DAB+ offering a huge amount of stations and content.

WiFi - The inclusion of a WiFi connection opens up your Bluetooth ceiling speaker system to multi-room capabilities. Modern wireless home networks are powerful and stable, with enough bandwidth to allow for a wireless audio system to function correctly. WiFi-enabled amplifiers and active speakers can be grouped via an app to allow easy music playback to the entire home or selected areas.

Ethernet - Provides the same functionality as WiFi, though via a wired connection. For an installation, especially during a refurb or building work, the use of network cable between multi-room audio devices offers bullet-proof stability, avoiding signal drop-out over WiFi, especially in a heavy-usage household with lots of devices on the wireless network.

Line Output - Some systems will include a line-level signal output, which can be in the form of RCA sockets, a 3.5mm stereo socket, or bare-wire terminals. This is a handy output for system expansion or larger areas as it allows you to link to an additional power amplifier.

Active Bluetooth ceiling speakers and wall-mount amplifiers are often around the 2x 25W mark, which is ample for a pair of speakers, but not enough to power several sets, along with the fact you will have issues wiring multiple low-impedance speakers together. The addition of an external power amplifier removes those issues and allows you to expand the system. You can even omit the units onboard amplifier entirely if you wish, running all speakers from the power amp.

Voice Control - Appearing on higher-end Bluetooth and WiFi amplifiers and speaker systems, the inclusion of direct voice command allows for services such as Amazon Alexa, Google Assistant, or Apple Homekit to control your audio playback. With a service subscription and internet connection, these speaker systems will work without a phone, tablet or external device, though they will still support a direct Bluetooth connection when required.

Where to Install Bluetooth Ceiling Speakers

It should go without saying that a ceiling speaker needs a ceiling, and one at a reasonable height. This rules out factories, warehouses, very high-ceiling homes, and outdoor areas. For those areas you would use wall speakers or pendant speakers

Even if you have a normal ceiling height, you must determine if there is enough cavity available to house the speaker's depth (which can be as much as 100mm on larger units). This depth is even larger if you are using fire hoods on the rear of your ceiling speakers.

Kitchen & Dining Areas - Perfect for background music while cooking or entertaining. The kitchen is often the hub of a home, and the ability to enjoy music or listen to a podcast without being tied to a phone or laptop makes these discreet, space-saving speaker systems a hugely enjoyable experience.

Living Rooms & Home Cinema - With line inputs and digital inputs, you can easily pair your ceiling speaker system with a TV for a more immersive sound experience, while keeping the living space free from the cumbersome boxes associated with a traditional stereo system. Line outputs allow the connection of an active subwoofer which will greatly enhance films and music.

Bedrooms - Taking the place of a desktop radio or small Hi-Fi system, a set of active Bluetooth ceiling speakers gives you wireless listening with the convenience of control from your mobile device. They offer ample volume and performance, whilst saving valuable space.

Bathrooms - This will depend on the system. For a moisture-heavy area such as a bathroom or shower room, the speakers must be of a suitable design, which means polypropylene woofers and aluminium or plastic grilles. Traditional speaker cones are made of paper and will absorb steam and condensation, which will rot the cone and cause the surface to tear.

If speakers have a moistureproof design they will clearly state this fact as a feature.

In-ceiling Bluetooth amplifiers will generally be fine, but wall-mount control panels must be able to withstand moisture and water splashes, ideally having some type of IP rating. Again, this should be clearly stated with any suitable unit as it’s a major selling point.

Commercial Spaces - Small offices and waiting rooms can benefit from unobtrusive audio. The simplicity of installation and operation means a Bluetooth ceiling speaker system or in-ceiling amplifier setup can provide some much-needed ambient noise to ward off those long silent times.

For larger premises though, we would suggest you look at a more suitable installation sound system, as both Bluetooth and WiFi will struggle in these situations.
