Edifier T5s Powered Subwoofer, 70W RMS, 8-Inch Woofer, 35Hz Bass

For a living-room stereo or home theater that needs more low-end weight, the Edifier T5s adds a powered subwoofer without requiring a separate amplifier. Its 8-inch long-throw woofer is rated for 70W RMS, and the stated frequency response reaches 35Hz. RCA connections make the setup a fit for compatible speakers or audio gear with the right inputs.

It’s a more direct route to adding bass than replacing a full speaker system, but connection options matter: the T5s has no wireless communication and uses RCA.

Why it’s worth it

The T5s combines a built-in Class-D amplifier with a long-throw woofer, so there’s no external receiver needed to power the subwoofer. A low-pass filter adjustable from 30Hz to 160Hz and a 0°/180° phase selector provide ways to tune how it blends with a connected speaker setup. Those controls are useful when placement or the sound of the main speakers calls for a different crossover or phase setting.

Buyers commonly praise the bass output, sound quality, and straightforward setup, and some appreciate its compact footprint. Feedback is less consistent on connectivity, noise level, and volume control. In particular, reports about speaker compatibility vary, so the connection method and ports on the exact speakers or amplifier are more useful to confirm than relying on a general compatibility claim.

Highlights

The black cabinet measures 15.71 inches deep, 6.69 inches wide, and 16.14 inches high. Its front-firing driver and right-firing acoustic port are part of a slim MDF enclosure, while the stated 10.38 kg weight is worth factoring in when choosing a spot. An auto-standby feature is listed to activate after 15 minutes of inactivity.

There are two described wired setups. If the speakers or amplifier have a subwoofer output, connect that output to the T5s Signal In and connect the main speakers to the source as usual. Without a sub out, the listed series connection runs the source into the T5s Signal In, then from its Signal Out to the main speaker, that speaker needs a Line In. Bluetooth, USB, optical, or other non-wired connections are not supported for this second arrangement. The product information also lists RCA and 3.5mm-to-RCA cables as included.

Usage tips

Before choosing a location, identify the available RCA outputs and inputs in the whole audio chain. The T5s itself is not wireless, even if a connected source or speaker system uses Bluetooth for another part of its setup. Start with the low-pass filter and phase selector as adjustment tools for integrating the subwoofer, rather than assuming one setting will suit every room and speaker pair.

Questions before you buy

Does the T5s need an external amplifier? No separate receiver is needed to power it, the subwoofer has a built-in amplifier. It still needs a compatible wired audio connection.

Can it connect to any Bluetooth speaker? Not wirelessly. The T5s uses RCA, so a Bluetooth speaker setup needs a compatible wired input or subwoofer output for the connection method being used.

What controls are available? The product information lists a 30Hz–160Hz low-pass filter and a 0°/180° phase selector. It also lists auto-standby after 15 minutes of inactivity.

When it makes sense

It makes sense if you want to add a powered subwoofer to an indoor stereo or home theater and your system offers a supported RCA connection. Compared with buying a subwoofer that depends on a separate amplifier, the built-in amp keeps this setup more self-contained. Better avoided if your intended system has no compatible wired RCA path, or if you need a wireless subwoofer connection, the listed specifications don’t provide one.
