The T5s is a slim active subwoofer from Edifier, launched around November 2025 at USD 199.99 in black or brown. It uses a front-firing 8-inch driver in a shallow vertical cabinet, so it can stand against a wall or beside furniture where a cube-shaped subwoofer would not fit, and it is designed to extend the bass of Edifier's powered speakers in living rooms and at desks.
Key specs that matter
A 220 mm (8-inch) long-throw driver faces forward and gets 70 W RMS from a closed-loop Class D amplifier fed by a high-efficiency switching supply. Frequency response is 35 Hz to 115 Hz and signal to noise ratio is 85 dB A-weighted or better. Inputs and outputs are RCA, with a signal input and a pass-through output, and input sensitivity is 150 mV plus or minus 20 mV. Volume, low-pass filter and phase can be adjusted with controls on the unit. The enclosure uses 18 mm MDF panels finished in wood-grain vinyl, with a low grille over the driver, and it is 399 mm wide, 400 mm high and 170 mm deep, weighing 10.38 kg.
Engineering and use context
A built-in DSP carries out the low-pass filtering and phase alignment digitally, which allows precise settings. Compared with the T5, the T5s reaches 3 Hz lower, but its upper limit is also lower, so it is intended to work below the range of the main speakers. Its slim vertical format trades depth for width and height, keeping enough internal volume for the 8-inch driver. It weighs 1.8 kg more than the T5. Auto standby switches it off after 15 minutes without signal, half the time of the T5. The higher input sensitivity of 150 mV means it expects a slightly stronger signal from the source than the T5. The front-firing driver sends bass directly into the room, even when the back of the cabinet is close to a wall. Its lower limit sits below those of the M60, QR65, R1700BTs and S880DB MKII, and it costs the same as the T5.
Pairing
The T5s connects to the subwoofer outputs of Edifier speakers such as the S880DB MKII, QR65 and R1700BTs, and the pass-through output allows it to sit between a source and powered speakers without a sub output. Its shallow depth suits placement beside a sofa, under a desk or against a wall in rooms of about 20 m2.
Alternatives
The Edifier T5 is the cube-shaped 8-inch model with the same amplifier rating, a 38 Hz to 160 Hz range and a 278 x 300 x 336 mm cabinet.
