Our take on the Focal Sub Air

Focal's Sub Air powered subwoofer stands out from the pack in a couple of cool ways. For one, it's shallow enough to literally mount on the wall — no need to sacrifice an inch of floor space. Focal even includes the mounting hardware you need to install it.

Deep, punchy bass from a shallow, wall-mountable sub

Focal's Sub Air powered subwoofer stands out from the pack in a couple of cool ways. For one, it's shallow enough to literally mount on the wall — no need to sacrifice an inch of floor space. Focal even includes the mounting hardware you need to install it.

Second, it's wireless, which opens up even more placement possibilities. Hook up the included transmitter to your receiver's subwoofer output, and place the sub anywhere within a 49-foot range. (Just remember: you will need to connect the subwoofer and the transmitter to AC power.)

Crutchfield Customer Review (What's this?)

I hooked up this sub with new speakers to an existing system. I wanted to give them some break-in while the area they will reside is being remolded. Very pleased with the quality of sound and amount of bass from this compact form. It will eventually be wall mounted and wireless. Hopefully this will not alter what I'm hearing now. Would buy again.

Pros: Small enclosure, easy set up, attractive, available in white, wall mountable, wireless included, Focal reputation.

Cons: It's not going to do what a big box can.

Product Research


Wireless Connectivity: The Focal Sub Air is equipped with a built-in wireless receiver and comes with an external wireless transmitter, so you don't have to run a subwoofer cable between your AV receiver or integrated amplifier and the powered sub. The external wireless transmitter features LFE/RCA inputs which connect to your AV receiver or integrated amplifier's LFE output or stereo preouts. The low-frequency audio signals from your receiver or amplifier are then wirelessly transmitted to the Sub Air's built-in wireless receiver. The Focal Sub Air has a wireless range of approximately 49'.

Note: The Focal Sub Air and the included wireless transmitter come wirelessly connected from the factory. It is only possible to connect one Sub Air powered subwoofer to one wireless transmitter at a time, and vice-versa.

8" Cellulose Pulp Cone Woofer: The Focal Sub Air wireless powered subwoofer features a 8" cellulose pulp cone woofer that sounds great for movie and music soundtracks.

Note: The driver used in the Sub Air is made up of complex mechanical elements and requires a break-in period before it delivers the best of its performances. Focal recommends that you to let the subwoofer operate for about twenty hours at medium level, playing standard music programs, but with a large amount of bass.

110W BASH Amplifier: The Focal Sub Air wireless powered subwoofer employs a built-in 110W (RMS)/150W Peak) BASH amplifier for dynamic bass response.

Bass Reflex Enclosure: The Focal Sub Air wireless powered subwoofer utilizes a bass reflex enclosure with a side-firing bass port for added efficiency and bigger bass response. The bass port has been finely tuned to prevent port noise and distortion. The enclosure is available in a gloss black or gloss white lacquer finish.

Sub Controls: The Focal Sub Air provides Volume, Crossover, and Phase controls on the bottom-panel.

  • Volume Level: The volume level controls the overall output level of the powered subwoofer, relative to the volume of the other speakers in your home theater or stereo system.
  • Low Pass Crossover: The Focal Sub Air is equipped with a variable low-pass crossover which can be set between 50Hz and 200Hz. If your AV receiver is equipped with an LFE output, make sure the set the Sub Air's low-pass crossover to the "LFE" setting.
  • Phase Switch: The phase switch allows for the adjustment of the phase of the powered subwoofer in relation to the speakers used in your audio system - either 0 or 180 degrees. If the bass sounds muddy or unclear, adjusting the phase control can sometimes strengthen the bass performance.

LFE/RCA Input: If you prefer a wired connection, the Focal Sub Air is also equipped with an LFE/stereo RCA input on the bottom-panel. Use the RCA input jack labeled "Right/LFE" for an LFE connection to your AV receiver. You will need to run a subwoofer cable (sold separately) from your AV receiver or integrated amplifier's LFE/RCA output to the powered sub.

Auto On/Standby: The Focal Sub Air will automatically power on when it detects an audio signal and go into standby mode when there is not audio signal present. You can also choose to manually turn the power of the Sub Air on and off.

Mounting & Placement Options: The Focal Sub Air wireless powered subwoofer can be simply placed on the floor using the included rubber feet or even mounted to a wall using the included wall-mount kit. Focal recommends placing the Sub Air wireless powered subwoofer in a corner towards the front of the room for optimum bass performance and a +6dB boost in bass output.

AC Power Requirements: Both the wireless powered subwoofer and wireless transmitter will require AC power. The wireless powered sub includes an 8' detachable AC power cord. The wireless transmitter includes an AC power adapter with an attached 6' DC cord.
